We're dividing 371206 by 31 
Let's see how many times 31 fits into 371206.

Going ahead to step 1:
If we divide 3 by 31, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 31

On to step 2:
If we divide 37 by 31, we get 1 and a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 6 after subtracting 31 from 37.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 31

Advancing to step 3:
61 divided by 31 is 1 with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 31 from 61 to get 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 31

Step 4:
302 divided by 31 is 9 with a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
Deduct 279 from 302 and we're left with 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 31

Step 5:
When dividing 230 by 31, we get 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 1197.0
If we subtract 217 from 230, we get 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 31

Moving on to step 6:
When dividing 136 by 31, we get 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 11974.0
If we subtract 124 from 136, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
If we divide 120 by 31, we get 3 and a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 11974.3
If we subtract 93 from 120, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 8:
When dividing 270 by 31, we get 8 with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 11974.38
If we subtract 248 from 270, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
220 divided by 31 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 11974.387
Deduct 217 from 220 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
31 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 11974.387
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
When dividing 300 by 31, we get 9 with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 11974.38709
If we subtract 279 from 300, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 12:
31 can be fit into 210 6 times, resulting in a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 11974.387096
If we subtract 186 from 210, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 13:
31 goes into 240 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 11974.3870967
If we subtract 217 from 240, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 14:
230 divided by 31 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 11974.38709677
If we take 217 away from 230, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 11974.38709677 with a balance of 1.3e-08.
