We look at the division of 31911258 by 431 
We're looking to find how many times 431 goes into 31911258.

On to step 1:
431 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 431

Advancing to step 2:
The number 431 fits into 31 0 times, leaving a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 431

Step 3:
The number 431 fits into 319 0 times, leaving a remainder of 319.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 319, we get 319.
Bring next digit (1) of the dividend behind the 319 and repeat the process: 3191 / 431

Let's proceed to step 4:
If we divide 3191 by 431, we get 7 and a remainder of 174.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 3017 from 3191, we get 174.
Grab the next digit (1) from the dividend, add it to 174, then carry on: 1741 / 431

Step 5:
When dividing 1741 by 431, we get 4 with a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 74.0
The remainder is 17 after subtracting 1724 from 1741.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 431

Let's proceed to step 6:
When dividing 172 by 431, we get 0 with a remainder of 172.
Use 0 as the next digit of our solution. 
Result so far: 740.0
The remainder is 172 after subtracting 0 from 172.
Fetch the next digit (5) from the dividend, attach it to 172 and continue: 1725 / 431

Step 7:
431 goes into 1725 4 times with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 7404.0
Deduct 1724 from 1725 and we're left with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 431

Let's proceed to step 8:
The number 431 fits into 18 0 times, leaving a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 74040.0
The remainder is 18 after subtracting 0 from 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
431 goes into 180 0 times with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 74040.0
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 10:
When dividing 1800 by 431, we get 4 with a remainder of 76.
The next digit of our result is 4. 
Result so far: 74040.04
Subtract 1724 from 1800 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
The number 431 fits into 760 1 times, leaving a remainder of 329.
Put 1 as the next digit of the answer. 
Result so far: 74040.041
The remainder is 329 after subtracting 431 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Moving on to step 12:
If we divide 3290 by 431, we get 7 and a remainder of 273.
The next digit of our result is 7. 
Result so far: 74040.0417
Deduct 3017 from 3290 and we're left with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

On to step 13:
When dividing 2730 by 431, we get 6 with a remainder of 144.
Write down 6 as next digit of the result. 
Result so far: 74040.04176
If we take 2586 away from 2730, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 14:
431 can be fit into 1440 3 times, resulting in a remainder of 147.
Put 3 as the next digit of the answer. 
Result so far: 74040.041763
The remainder is 147 after subtracting 1293 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Step 15:
If we divide 1470 by 431, we get 3 and a remainder of 177.
Put 3 as the next digit of the answer. 
Result so far: 74040.0417633
Subtract 1293 from 1470 to get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

The quotient of the division is 74040.0417633, and the remainder is 1.77e-06.
