Let's divide 625845 by 72
The aim is to understand the frequency of 72 in 625845.

Step 1:
If we divide 6 by 72, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 72

Advancing to step 2:
The number 72 fits into 62 0 times, leaving a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Grab the next digit (5) from the dividend, add it to 62, then carry on: 625 / 72

Going ahead to step 3:
72 goes into 625 8 times with a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 49 after subtracting 576 from 625.
Append the next digit (8) from the dividend to 49 and continue with: 498 / 72

Moving on to step 4:
72 can be fit into 498 6 times, resulting in a remainder of 66.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtract 432 from 498 to get 66.
Take the next digit (4) from the dividend and append it to 66, then repeat: 664 / 72

Step 5:
The number 72 fits into 664 9 times, leaving a remainder of 16.
The next digit of our result is 9. 
Result so far: 869.0
Subtracting 648 from 664 leaves us with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 72

Step 6:
165 divided by 72 is 2 with a remainder of 21.
The next digit of our result is 2. 
Result so far: 8692.0
Deduct 144 from 165 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
210 divided by 72 is 2 with a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 8692.2
Subtract 144 from 210 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 8:
72 can be fit into 660 9 times, resulting in a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 8692.29
Subtracting 648 from 660 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
If we divide 120 by 72, we get 1 and a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 8692.291
If we take 72 away from 120, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
The number 72 fits into 480 6 times, leaving a remainder of 48.
The next digit of our result is 6. 
Result so far: 8692.2916
Deduct 432 from 480 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
72 can be fit into 480 6 times, resulting in a remainder of 48.
The next digit of our result is 6. 
Result so far: 8692.29166
The remainder is 48 after subtracting 432 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 8692.29166 with a remainder of 4.8e-05.
