We look at the division of 31271190 by 215 
We want to divide 31271190 by 215.

Step 1:
If we divide 3 by 215, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 215

Step 2:
215 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Bring next digit (2) of the dividend behind the 31 and repeat the process: 312 / 215

Going ahead to step 3:
215 goes into 312 1 times with a remainder of 97.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 215 from 312 and we're left with 97.
Grab the next digit (7) from the dividend, add it to 97, then carry on: 977 / 215

Going ahead to step 4:
When dividing 977 by 215, we get 4 with a remainder of 117.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 860 from 977 to get 117.
Grab the next digit (1) from the dividend, add it to 117, then carry on: 1171 / 215

On to step 5:
When dividing 1171 by 215, we get 5 with a remainder of 96.
Use 5 as the next digit of our solution. 
Result so far: 145.0
Subtracting 1075 from 1171 leaves us with 96.
Append the next digit (1) from the dividend to 96 and continue with: 961 / 215

Moving on to step 6:
If we divide 961 by 215, we get 4 and a remainder of 101.
The next digit of our result is 4. 
Result so far: 1454.0
Subtract 860 from 961 to get 101.
Fetch the next digit (9) from the dividend, attach it to 101 and continue: 1019 / 215

Moving on to step 7:
When dividing 1019 by 215, we get 4 with a remainder of 159.
Record the quotient 4 as the next digit in the result. 
Result so far: 14544.0
Subtracting 860 from 1019 leaves us with 159.
Fetch the next digit (0) from the dividend, attach it to 159 and continue: 1590 / 215

Step 8:
215 can be fit into 1590 7 times, resulting in a remainder of 85.
Use 7 as the next digit of our solution. 
Result so far: 145447.0
The remainder is 85 after subtracting 1505 from 1590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 9:
215 goes into 850 3 times with a remainder of 205.
Put 3 as the next digit of the answer. 
Result so far: 145447.3
The remainder is 205 after subtracting 645 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 10:
When dividing 2050 by 215, we get 9 with a remainder of 115.
Write down 9 as next digit of the result. 
Result so far: 145447.39
Subtracting 1935 from 2050 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 11:
When dividing 1150 by 215, we get 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 145447.395
Subtract 1075 from 1150 to 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.

Let's proceed to step 12:
215 can be fit into 750 3 times, resulting in a remainder of 105.
Record the quotient 3 as the next digit in the result. 
Result so far: 145447.3953
Subtract 645 from 750 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 13:
215 goes into 1050 4 times with a remainder of 190.
Put 4 as the next digit of the answer. 
Result so far: 145447.39534
Subtracting 860 from 1050 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 14:
215 can be fit into 1900 8 times, resulting in a remainder of 180.
Use 8 as the next digit of our solution. 
Result so far: 145447.395348
If we subtract 1720 from 1900, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 15:
The number 215 fits into 1800 8 times, leaving a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 145447.3953488
Subtracting 1720 from 1800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 145447.3953488 with a remaining 8e-07.
