65099857 ÷ 725 
We want to figure out the number of times 65099857 can be divided by 725.

On to step 1:
6 divided by 725 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 725

On to step 2:
The number 725 fits into 65 0 times, leaving a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 65 after subtracting 0 from 65.
Bring next digit (0) of the dividend behind the 65 and repeat the process: 650 / 725

Advancing to step 3:
If we divide 650 by 725, we get 0 and a remainder of 650.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 650, we end up with 650.
Fetch the next digit (9) from the dividend, attach it to 650 and continue: 6509 / 725

Moving on to step 4:
The number 725 fits into 6509 8 times, leaving a remainder of 709.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 709 after subtracting 5800 from 6509.
Take the next digit (9) from the dividend and append it to 709, then repeat: 7099 / 725

Advancing to step 5:
725 goes into 7099 9 times with a remainder of 574.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
Subtract 6525 from 7099 to get 574.
Grab the next digit (8) from the dividend, add it to 574, then carry on: 5748 / 725

On to step 6:
725 can be fit into 5748 7 times, resulting in a remainder of 673.
Put 7 as the next digit of the answer. 
Result so far: 897.0
Subtract 5075 from 5748 to get 673.
Include the next digit (5) from the dividend after 673, then repeat: 6735 / 725

On to step 7:
If we divide 6735 by 725, we get 9 and a remainder of 210.
The next digit of our result is 9. 
Result so far: 8979.0
The remainder is 210 after subtracting 6525 from 6735.
Grab the next digit (7) from the dividend, add it to 210, then carry on: 2107 / 725

On to step 8:
If we divide 2107 by 725, we get 2 and a remainder of 657.
Write down 2 as next digit of the result. 
Result so far: 89792.0
Deduct 1450 from 2107 and we're left with 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Advancing to step 9:
If we divide 6570 by 725, we get 9 and a remainder of 45.
The number 9 becomes the next digit in our result. 
Result so far: 89792.9
Subtract 6525 from 6570 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 10:
725 goes into 450 0 times with a remainder of 450.
The next digit of our result is 0. 
Result so far: 89792.9
Subtract 0 from 450 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 11:
725 goes into 4500 6 times with a remainder of 150.
Put 6 as the next digit of the answer. 
Result so far: 89792.906
Subtract 4350 from 4500 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 12:
725 can be fit into 1500 2 times, resulting in a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 89792.9062
Subtracting 1450 from 1500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
If we divide 500 by 725, we get 0 and a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 89792.9062
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 14:
725 goes into 5000 6 times with a remainder of 650.
Write down 6 as next digit of the result. 
Result so far: 89792.906206
Subtract 4350 from 5000 to get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Let's proceed to step 15:
725 can be fit into 6500 8 times, resulting in a remainder of 700.
The next digit of our result is 8. 
Result so far: 89792.9062068
If we subtract 5800 from 6500, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Advancing to step 16:
When dividing 7000 by 725, we get 9 with a remainder of 475.
Write down 9 as next digit of the result. 
Result so far: 89792.90620689
Subtracting 6525 from 7000 leaves us with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

The final result is 89792.90620689 with a remainder of 4.75e-07.
