We're dividing 113712 by 31 
We want to divide 113712 by 31.

Let's proceed to step 1:
The number 31 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 31

Advancing to step 2:
The number 31 fits into 11 0 times, leaving a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 31

Let's proceed to step 3:
31 can be fit into 113 3 times, resulting in a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 93 away from 113, we end up with 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 31

Step 4:
The number 31 fits into 207 6 times, leaving a remainder of 21.
Put 6 as the next digit of the answer. 
Result so far: 36.0
The remainder is 21 after subtracting 186 from 207.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 31

Step 5:
31 goes into 211 6 times with a remainder of 25.
Use 6 as the next digit of our solution. 
Result so far: 366.0
The remainder is 25 after subtracting 186 from 211.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 31

On to step 6:
When dividing 252 by 31, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 3668.0
Subtract 248 from 252 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
40 divided by 31 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 3668.1
If we take 31 away from 40, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 8:
If we divide 90 by 31, we get 2 and a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 3668.12
If we take 62 away from 90, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
If we divide 280 by 31, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 3668.129
If we subtract 279 from 280, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
10 divided by 31 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 3668.129
Subtracting 0 from 10 leaves us 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.

Going ahead to step 11:
100 divided by 31 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 3668.12903
Subtract 93 from 100 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 12:
If we divide 70 by 31, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 3668.129032
Subtract 62 from 70 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
80 divided by 31 is 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 3668.1290322
If we take 62 away from 80, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 3668.1290322 and a remainder of 1.8e-07.
