Let's divide 912429 by 31
We're looking to find how many times 31 goes into 912429.

Going ahead to step 1:
9 divided by 31 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 31

Let's proceed to step 2:
If we divide 91 by 31, we get 2 and a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 62 from 91, we get 29.
Fetch the next digit (2) from the dividend, attach it to 29 and continue: 292 / 31

On to step 3:
When dividing 292 by 31, we get 9 with a remainder of 13.
The next digit of our result is 9. 
Result so far: 29.0
Subtract 279 from 292 to get 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 31

On to step 4:
When dividing 134 by 31, we get 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 294.0
If we subtract 124 from 134, we get 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 31

Let's proceed to step 5:
When dividing 102 by 31, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 2943.0
If we take 93 away from 102, we end up with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 31

Moving on to step 6:
If we divide 99 by 31, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 29433.0
Subtract 93 from 99 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
31 can be fit into 60 1 times, resulting in a remainder of 29.
The next digit of our result is 1. 
Result so far: 29433.1
Subtracting 31 from 60 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 8:
The number 31 fits into 290 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 29433.19
If we take 279 away from 290, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
When dividing 110 by 31, we get 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 29433.193
Subtract 93 from 110 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
If we divide 170 by 31, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 29433.1935
Subtracting 155 from 170 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
31 can be fit into 150 4 times, resulting in a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 29433.19354
The remainder is 26 after subtracting 124 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
31 can be fit into 260 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 29433.193548
If we subtract 248 from 260, 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.

Going ahead to step 13:
120 divided by 31 is 3 with a remainder of 27.
The next digit of our result is 3. 
Result so far: 29433.1935483
If we take 93 away from 120, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 14:
When dividing 270 by 31, we get 8 with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 29433.19354838
The remainder is 22 after subtracting 248 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 29433.19354838 with a remainder of 2.2e-08.
