We're dividing 39576651 by 815 
We're looking to find how many times 815 goes into 39576651.

Let's proceed to step 1:
815 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 815

Let's proceed to step 2:
815 can be fit into 39 0 times, resulting in a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Append the next digit (5) from the dividend to 39 and continue with: 395 / 815

Going ahead to step 3:
The number 815 fits into 395 0 times, leaving a remainder of 395.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 395, we get 395.
Append the next digit (7) from the dividend to 395 and continue with: 3957 / 815

Advancing to step 4:
3957 divided by 815 is 4 with a remainder of 697.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 697 after subtracting 3260 from 3957.
Take the next digit (6) from the dividend and append it to 697, then repeat: 6976 / 815

Moving on to step 5:
815 goes into 6976 8 times with a remainder of 456.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Deduct 6520 from 6976 and we're left with 456.
Grab the next digit (6) from the dividend, add it to 456, then carry on: 4566 / 815

Advancing to step 6:
815 can be fit into 4566 5 times, resulting in a remainder of 491.
The number 5 becomes the next digit in our result. 
Result so far: 485.0
If we take 4075 away from 4566, we end up with 491.
Include the next digit (5) from the dividend after 491, then repeat: 4915 / 815

Advancing to step 7:
If we divide 4915 by 815, we get 6 and a remainder of 25.
The number 6 becomes the next digit in our result. 
Result so far: 4856.0
Subtracting 4890 from 4915 leaves us with 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 815

Going ahead to step 8:
251 divided by 815 is 0 with a remainder of 251.
The next digit of our result is 0. 
Result so far: 48560.0
The remainder is 251 after subtracting 0 from 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Moving on to step 9:
2510 divided by 815 is 3 with a remainder of 65.
Use 3 as the next digit of our solution. 
Result so far: 48560.3
The remainder is 65 after subtracting 2445 from 2510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 10:
815 can be fit into 650 0 times, resulting in a remainder of 650.
The number 0 becomes the next digit in our result. 
Result so far: 48560.3
Subtract 0 from 650 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.

On to step 11:
When dividing 6500 by 815, we get 7 with a remainder of 795.
Record the quotient 7 as the next digit in the result. 
Result so far: 48560.307
If we take 5705 away from 6500, we end up with 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

Moving on to step 12:
When dividing 7950 by 815, we get 9 with a remainder of 615.
Put 9 as the next digit of the answer. 
Result so far: 48560.3079
Deduct 7335 from 7950 and we're left with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Moving on to step 13:
If we divide 6150 by 815, we get 7 and a remainder of 445.
Use 7 as the next digit of our solution. 
Result so far: 48560.30797
If we take 5705 away from 6150, we end up with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Going ahead to step 14:
815 can be fit into 4450 5 times, resulting in a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 48560.307975
If we subtract 4075 from 4450, 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.

On to step 15:
3750 divided by 815 is 4 with a remainder of 490.
The number 4 becomes the next digit in our result. 
Result so far: 48560.3079754
If we subtract 3260 from 3750, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 16:
815 goes into 4900 6 times with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 48560.30797546
If we take 4890 away from 4900, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 48560.30797546, with a leftover of 1e-08.
