We're dividing 57870616 by 725 
The aim is to understand the frequency of 725 in 57870616.

On to step 1:
When dividing 5 by 725, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 725

Step 2:
725 goes into 57 0 times with a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Include the next digit (8) from the dividend after 57, then repeat: 578 / 725

On to step 3:
If we divide 578 by 725, we get 0 and a remainder of 578.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 578 to get 578.
Take the next digit (7) from the dividend and append it to 578, then repeat: 5787 / 725

On to step 4:
725 can be fit into 5787 7 times, resulting in a remainder of 712.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 5075 from 5787 leaves us with 712.
Grab the next digit (0) from the dividend, add it to 712, then carry on: 7120 / 725

Going ahead to step 5:
When dividing 7120 by 725, we get 9 with a remainder of 595.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
The remainder is 595 after subtracting 6525 from 7120.
Fetch the next digit (6) from the dividend, attach it to 595 and continue: 5956 / 725

Moving on to step 6:
725 goes into 5956 8 times with a remainder of 156.
The next digit of our result is 8. 
Result so far: 798.0
Subtracting 5800 from 5956 leaves us with 156.
Fetch the next digit (1) from the dividend, attach it to 156 and continue: 1561 / 725

On to step 7:
725 goes into 1561 2 times with a remainder of 111.
The number 2 becomes the next digit in our result. 
Result so far: 7982.0
The remainder is 111 after subtracting 1450 from 1561.
Take the next digit (6) from the dividend and append it to 111, then repeat: 1116 / 725

Going ahead to step 8:
If we divide 1116 by 725, we get 1 and a remainder of 391.
Write down 1 as next digit of the result. 
Result so far: 79821.0
Subtract 725 from 1116 to get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Moving on to step 9:
The number 725 fits into 3910 5 times, leaving a remainder of 285.
Put 5 as the next digit of the answer. 
Result so far: 79821.5
If we subtract 3625 from 3910, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 10:
The number 725 fits into 2850 3 times, leaving a remainder of 675.
The number 3 becomes the next digit in our result. 
Result so far: 79821.53
If we subtract 2175 from 2850, we get 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Going ahead to step 11:
If we divide 6750 by 725, we get 9 and a remainder of 225.
Write down 9 as next digit of the result. 
Result so far: 79821.539
Subtracting 6525 from 6750 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 12:
2250 divided by 725 is 3 with a remainder of 75.
Use 3 as the next digit of our solution. 
Result so far: 79821.5393
If we subtract 2175 from 2250, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 13:
If we divide 750 by 725, we get 1 and a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 79821.53931
Deduct 725 from 750 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 14:
725 can be fit into 250 0 times, resulting in a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 79821.53931
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 15:
725 goes into 2500 3 times with a remainder of 325.
Put 3 as the next digit of the answer. 
Result so far: 79821.5393103
If we take 2175 away from 2500, we end up with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 16:
If we divide 3250 by 725, we get 4 and a remainder of 350.
Use 4 as the next digit of our solution. 
Result so far: 79821.53931034
Subtract 2900 from 3250 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

The final outcome is 79821.53931034, with a leftover of 3.5e-07.
