428437 divided by 31 
We're looking to find how many times 31 goes into 428437.

Moving on to step 1:
If we divide 4 by 31, we get 0 and 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.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 31

Going ahead to step 2:
42 divided by 31 is 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 11 after subtracting 31 from 42.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 31

Going ahead to step 3:
When dividing 118 by 31, we get 3 with a remainder of 25.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 93 from 118 and we're left with 25.
Grab the next digit (4) from the dividend, add it to 25, then carry on: 254 / 31

Moving on to step 4:
31 goes into 254 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 138.0
Subtracting 248 from 254 leaves us with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 31

Advancing to step 5:
If we divide 63 by 31, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 1382.0
If we subtract 62 from 63, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 31

On to step 6:
If we divide 17 by 31, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 13820.0
Subtract 0 from 17 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.

Moving on to step 7:
31 can be fit into 170 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 13820.5
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.

On to step 8:
31 goes into 150 4 times with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 13820.54
Subtract 124 from 150 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
31 can be fit into 260 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 13820.548
If we take 248 away from 260, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
The number 31 fits into 120 3 times, leaving a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 13820.5483
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 11:
The number 31 fits into 270 8 times, leaving a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 13820.54838
Subtract 248 from 270 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
If we divide 220 by 31, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 13820.548387
Subtract 217 from 220 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 13:
31 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 13820.548387
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
The number 31 fits into 300 9 times, leaving a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 13820.54838709
Deduct 279 from 300 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The quotient of the division is 13820.54838709, and the remainder is 2.1e-08.
