We look at the division of 29686 by 31 
We want to divide 29686 by 31.

Let's proceed to step 1:
The number 31 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 31

Let's proceed to step 2:
If we divide 29 by 31, we get 0 and a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 31

Advancing to step 3:
31 can be fit into 296 9 times, resulting in a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 279 from 296, we get 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 31

Step 4:
31 goes into 178 5 times with a remainder of 23.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
Subtracting 155 from 178 leaves us with 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 31

Advancing to step 5:
When dividing 236 by 31, we get 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 957.0
If we take 217 away from 236, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 6:
31 can be fit into 190 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 957.6
Subtract 186 from 190 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.

Moving on to step 7:
When dividing 40 by 31, we get 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 957.61
If we subtract 31 from 40, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 8:
31 can be fit into 90 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 957.612
Subtracting 62 from 90 leaves us 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:
31 can be fit into 280 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 957.6129
If we take 279 away from 280, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 10:
The number 31 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 957.6129
Deduct 0 from 10 and we're left 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.

Advancing to step 11:
31 can be fit into 100 3 times, resulting in a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 957.612903
Deduct 93 from 100 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

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: 957.6129032
If we subtract 62 from 70, we 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.

Let's proceed to step 13:
31 goes into 80 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 957.61290322
If we subtract 62 from 80, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 957.61290322 with a balance of 1.8e-08.
