An animation of a frequency divider implemented with D flip-flops, counting from 0 to 7 in binary. For power-of-2 integer division, a simple binary counter can be used, clocked by the input signal. The least-significant output bit alternates at 1/2 the rate of the input clock, the next bit at 1/4 the rate, the third bit at 1/8 the rate, etc.
A prescaler is an electronic counting circuit used to reduce a high frequency electrical signal to a lower frequency by integer division.The prescaler takes the basic timer clock frequency (which may be the CPU clock frequency or may be some higher or lower frequency) and divides it by some value before feeding it to the timer, according to how the prescaler register(s) are configured.

The key to the ability of a frequency synthesizer to generate multiple frequencies is the divider placed between the output and the feedback input. This is usually in the form of a digital counter, with the output signal acting as a clock signal. The counter is preset to some initial count value, and counts down at each cycle of the clock signal.
Voltage changes on the five outputs of the binary counter counting from 00000, left to 11111 (or 31), right (vertically). In digital logic and computing, a counter is a device which stores (and sometimes displays) the number of times a particular event or process has occurred, often in relationship to a clock.

A pulse-swallowing counter is a component in an all-digital feedback system. The divider produces one output pulse for every N counts (N is usually a power of 2) when not swallowing, and per N+1 pulses when the 'swallow' signal is active. The overall pulse-swallowing system is used as part of a fractional-N frequency divider. [1]
Most frequency counters work by using a counter, which accumulates the number of events occurring within a specific period of time.After a preset period known as the gate time (1 second, for example), the value in the counter is transferred to a display, and the counter is reset to zero.
