We divide 31237579 by 815
We're looking to find how many times 815 goes into 31237579.

On to step 1:
If we divide 3 by 815, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 815

Let's proceed to step 2:
If we divide 31 by 815, we get 0 and a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 815

Step 3:
When dividing 312 by 815, we get 0 with a remainder of 312.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 312 and we're left with 312.
Fetch the next digit (3) from the dividend, attach it to 312 and continue: 3123 / 815

Moving on to step 4:
815 can be fit into 3123 3 times, resulting in a remainder of 678.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 2445 from 3123, we get 678.
Include the next digit (7) from the dividend after 678, then repeat: 6787 / 815

Advancing to step 5:
815 goes into 6787 8 times with a remainder of 267.
Write down 8 as next digit of the result. 
Result so far: 38.0
The remainder is 267 after subtracting 6520 from 6787.
Bring next digit (5) of the dividend behind the 267 and repeat the process: 2675 / 815

Advancing to step 6:
If we divide 2675 by 815, we get 3 and a remainder of 230.
The number 3 becomes the next digit in our result. 
Result so far: 383.0
Deduct 2445 from 2675 and we're left with 230.
Fetch the next digit (7) from the dividend, attach it to 230 and continue: 2307 / 815

Step 7:
815 can be fit into 2307 2 times, resulting in a remainder of 677.
Record the quotient 2 as the next digit in the result. 
Result so far: 3832.0
If we take 1630 away from 2307, we end up with 677.
Bring next digit (9) of the dividend behind the 677 and repeat the process: 6779 / 815

Let's proceed to step 8:
When dividing 6779 by 815, we get 8 with a remainder of 259.
Put 8 as the next digit of the answer. 
Result so far: 38328.0
Subtracting 6520 from 6779 leaves us with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Let's proceed to step 9:
815 goes into 2590 3 times with a remainder of 145.
Record the quotient 3 as the next digit in the result. 
Result so far: 38328.3
If we subtract 2445 from 2590, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 10:
1450 divided by 815 is 1 with a remainder of 635.
The number 1 becomes the next digit in our result. 
Result so far: 38328.31
If we take 815 away from 1450, we end up with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Moving on to step 11:
If we divide 6350 by 815, we get 7 and a remainder of 645.
Record the quotient 7 as the next digit in the result. 
Result so far: 38328.317
The remainder is 645 after subtracting 5705 from 6350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Advancing to step 12:
815 goes into 6450 7 times with a remainder of 745.
The number 7 becomes the next digit in our result. 
Result so far: 38328.3177
If we subtract 5705 from 6450, we get 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

Our division results in 38328.3177 with a remaining 0.00745.
