75267647 divided by 725 
The aim is to understand the frequency of 725 in 75267647.

On to step 1:
7 divided by 725 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 725

Step 2:
725 goes into 75 0 times with a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Grab the next digit (2) from the dividend, add it to 75, then carry on: 752 / 725

Moving on to step 3:
If we divide 752 by 725, we get 1 and a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 725 from 752, we get 27.
Grab the next digit (6) from the dividend, add it to 27, then carry on: 276 / 725

Moving on to step 4:
725 goes into 276 0 times with a remainder of 276.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 276, we end up with 276.
Grab the next digit (7) from the dividend, add it to 276, then carry on: 2767 / 725

On to step 5:
When dividing 2767 by 725, we get 3 with a remainder of 592.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
If we take 2175 away from 2767, we end up with 592.
Include the next digit (6) from the dividend after 592, then repeat: 5926 / 725

On to step 6:
725 can be fit into 5926 8 times, resulting in a remainder of 126.
The next digit of our result is 8. 
Result so far: 1038.0
Deduct 5800 from 5926 and we're left with 126.
Grab the next digit (4) from the dividend, add it to 126, then carry on: 1264 / 725

Going ahead to step 7:
725 goes into 1264 1 times with a remainder of 539.
Record the quotient 1 as the next digit in the result. 
Result so far: 10381.0
If we subtract 725 from 1264, we get 539.
Fetch the next digit (7) from the dividend, attach it to 539 and continue: 5397 / 725

Advancing to step 8:
If we divide 5397 by 725, we get 7 and a remainder of 322.
The next digit of our result is 7. 
Result so far: 103817.0
Subtract 5075 from 5397 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 9:
3220 divided by 725 is 4 with a remainder of 320.
The number 4 becomes the next digit in our result. 
Result so far: 103817.4
Subtract 2900 from 3220 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 10:
When dividing 3200 by 725, we get 4 with a remainder of 300.
The number 4 becomes the next digit in our result. 
Result so far: 103817.44
The remainder is 300 after subtracting 2900 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Our division results in 103817.44 with a remaining 0.3.
