21627 divided by 25 
The aim is to understand the frequency of 25 in 21627.

Going ahead to step 1:
The number 25 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 25

On to step 2:
When dividing 21 by 25, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 25

Advancing to step 3:
If we divide 216 by 25, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 200 from 216 and we're left with 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 25

Advancing to step 4:
If we divide 162 by 25, we get 6 and a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Subtracting 150 from 162 leaves us with 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 25

Going ahead to step 5:
If we divide 127 by 25, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 865.0
Deduct 125 from 127 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 6:
20 divided by 25 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 865.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
200 divided by 25 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 865.08
Subtracting 200 from 200 leaves us with 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 8:
0 divided by 25 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 865.08
Subtracting 0 from 0 leaves us with 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 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 865.08
If we take 0 away from 0, we end up with 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 865.08, and the remainder is 0.0.
