We're dividing 79002856 by 725 
The aim is to understand the frequency of 725 in 79002856.

Step 1:
When dividing 7 by 725, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 725

On to step 2:
If we divide 79 by 725, we get 0 and a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Grab the next digit (0) from the dividend, add it to 79, then carry on: 790 / 725

Going ahead to step 3:
725 goes into 790 1 times with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 725 from 790, we get 65.
Bring next digit (0) of the dividend behind the 65 and repeat the process: 650 / 725

Moving on to step 4:
650 divided by 725 is 0 with a remainder of 650.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 650 after subtracting 0 from 650.
Bring next digit (2) of the dividend behind the 650 and repeat the process: 6502 / 725

Going ahead to step 5:
When dividing 6502 by 725, we get 8 with a remainder of 702.
Put 8 as the next digit of the answer. 
Result so far: 108.0
Subtract 5800 from 6502 to get 702.
Append the next digit (8) from the dividend to 702 and continue with: 7028 / 725

Advancing to step 6:
When dividing 7028 by 725, we get 9 with a remainder of 503.
The number 9 becomes the next digit in our result. 
Result so far: 1089.0
If we subtract 6525 from 7028, we get 503.
Take the next digit (5) from the dividend and append it to 503, then repeat: 5035 / 725

Let's proceed to step 7:
725 goes into 5035 6 times with a remainder of 685.
The next digit of our result is 6. 
Result so far: 10896.0
If we take 4350 away from 5035, we end up with 685.
Append the next digit (6) from the dividend to 685 and continue with: 6856 / 725

Going ahead to step 8:
725 goes into 6856 9 times with a remainder of 331.
The number 9 becomes the next digit in our result. 
Result so far: 108969.0
Subtracting 6525 from 6856 leaves us with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Advancing to step 9:
725 can be fit into 3310 4 times, resulting in a remainder of 410.
The number 4 becomes the next digit in our result. 
Result so far: 108969.4
Subtract 2900 from 3310 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 10:
725 goes into 4100 5 times with a remainder of 475.
Put 5 as the next digit of the answer. 
Result so far: 108969.45
The remainder is 475 after subtracting 3625 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Moving on to step 11:
4750 divided by 725 is 6 with a remainder of 400.
Record the quotient 6 as the next digit in the result. 
Result so far: 108969.456
If we subtract 4350 from 4750, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 12:
If we divide 4000 by 725, we get 5 and a remainder of 375.
The next digit of our result is 5. 
Result so far: 108969.4565
If we subtract 3625 from 4000, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 13:
725 goes into 3750 5 times with a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 108969.45655
Deduct 3625 from 3750 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

After the division, we end up with 108969.45655 and a remainder of 0.000125.
