We're dividing 429924 by 31 
We want to figure out the number of times 429924 can be divided by 31.

Advancing to step 1:
31 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 31

Advancing to step 2:
31 goes into 42 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 31 from 42 and we're left with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 31

Step 3:
31 goes into 119 3 times with a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 93 from 119 leaves us with 26.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 31

Moving on to step 4:
269 divided by 31 is 8 with a remainder of 21.
Use 8 as the next digit of our solution. 
Result so far: 138.0
Subtract 248 from 269 to get 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 31

Step 5:
The number 31 fits into 212 6 times, leaving a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 1386.0
Deduct 186 from 212 and we're left with 26.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 31

Let's proceed to step 6:
31 can be fit into 264 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 13868.0
Deduct 248 from 264 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
When dividing 160 by 31, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 13868.5
The remainder is 5 after subtracting 155 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
The number 31 fits into 50 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 13868.51
The remainder is 19 after subtracting 31 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 9:
190 divided by 31 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 13868.516
Subtracting 186 from 190 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
The number 31 fits into 40 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 13868.5161
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.

Let's proceed to step 11:
31 can be fit into 90 2 times, resulting in a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 13868.51612
Deduct 62 from 90 and we're left 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.

Moving on to step 12:
280 divided by 31 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 13868.516129
Subtract 279 from 280 to 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.

Going ahead to step 13:
When dividing 10 by 31, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 13868.516129
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
The number 31 fits into 100 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 13868.51612903
Subtracting 93 from 100 leaves us 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.

The final outcome is 13868.51612903, with a leftover of 7e-09.
