429893 ÷ 31 
We're looking to find how many times 31 goes into 429893.

Going ahead to step 1:
If we divide 4 by 31, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 31

Going ahead to step 2:
31 goes into 42 1 times with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 31 from 42, we get 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 31

On to step 3:
If we divide 119 by 31, we get 3 and a remainder of 26.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 93 from 119 to get 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 31

Step 4:
268 divided by 31 is 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
Subtracting 248 from 268 leaves us with 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 31

Moving on to step 5:
The number 31 fits into 209 6 times, leaving a remainder of 23.
The number 6 becomes the next digit in our result. 
Result so far: 1386.0
If we take 186 away from 209, we end up with 23.
Include the next digit (3) from the dividend after 23, then repeat: 233 / 31

On to step 6:
31 can be fit into 233 7 times, resulting in a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 13867.0
The remainder is 16 after subtracting 217 from 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
When dividing 160 by 31, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 13867.5
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.

Moving on to step 8:
50 divided by 31 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 13867.51
If we take 31 away from 50, 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.

Moving on to step 9:
190 divided by 31 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 13867.516
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.

On to step 10:
40 divided by 31 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 13867.5161
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.

Going ahead to step 11:
The number 31 fits into 90 2 times, leaving a remainder of 28.
The next digit of our result is 2. 
Result so far: 13867.51612
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.

Moving on to step 12:
280 divided by 31 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 13867.516129
Subtracting 279 from 280 leaves us 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.

Going ahead to step 13:
31 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 13867.516129
If we take 0 away from 10, we end up 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.

Let's proceed to step 14:
The number 31 fits into 100 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 13867.51612903
The remainder is 7 after subtracting 93 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 13867.51612903 and a remainder of 7e-09.
