We look at the division of 434086 by 31 
Let's see how many times 31 fits into 434086.

Step 1:
When dividing 4 by 31, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 31

Going ahead to step 2:
When dividing 43 by 31, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 31 from 43, we get 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 31

Step 3:
When dividing 124 by 31, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 124 from 124 and we're left with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 31

Moving on to step 4:
31 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 140.0
Deduct 0 from 0 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 31

Step 5:
31 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 1400.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 31

Moving on to step 6:
The number 31 fits into 86 2 times, leaving a remainder of 24.
The next digit of our result is 2. 
Result so far: 14002.0
Subtracting 62 from 86 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
The number 31 fits into 240 7 times, leaving a remainder of 23.
The next digit of our result is 7. 
Result so far: 14002.7
Deduct 217 from 240 and we're left with 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 8:
If we divide 230 by 31, we get 7 and a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 14002.77
Subtracting 217 from 230 leaves us 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.

The final outcome is 14002.77, with a leftover of 0.013.
