We divide 23621 by 79
The aim is to understand the frequency of 79 in 23621.

Advancing to step 1:
When dividing 2 by 79, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 79

Step 2:
23 divided by 79 is 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Fetch the next digit (6) from the dividend, attach it to 23 and continue: 236 / 79

Advancing to step 3:
When dividing 236 by 79, we get 2 with a remainder of 78.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 158 from 236 leaves us with 78.
Grab the next digit (2) from the dividend, add it to 78, then carry on: 782 / 79

Advancing to step 4:
782 divided by 79 is 9 with a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Subtracting 711 from 782 leaves us with 71.
Bring next digit (1) of the dividend behind the 71 and repeat the process: 711 / 79

Going ahead to step 5:
If we divide 711 by 79, we get 9 and a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 299.0
If we subtract 711 from 711, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 6:
If we divide 0 by 79, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 299.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
If we divide 0 by 79, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 299.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 299.0, and the remainder is 0.0.
