Let's divide 31979768 by 431
We're looking to find how many times 431 goes into 31979768.

On to step 1:
The number 431 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 431

Going ahead 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
The remainder is 31 after subtracting 0 from 31.
Bring next digit (9) of the dividend behind the 31 and repeat the process: 319 / 431

On to step 3:
The number 431 fits into 319 0 times, leaving a remainder of 319.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 319 and we're left with 319.
Take the next digit (7) from the dividend and append it to 319, then repeat: 3197 / 431

On to step 4:
431 goes into 3197 7 times with a remainder of 180.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 3017 from 3197 and we're left with 180.
Bring next digit (9) of the dividend behind the 180 and repeat the process: 1809 / 431

Let's proceed to step 5:
431 goes into 1809 4 times with a remainder of 85.
Write down 4 as next digit of the result. 
Result so far: 74.0
If we take 1724 away from 1809, we end up with 85.
Grab the next digit (7) from the dividend, add it to 85, then carry on: 857 / 431

Going ahead to step 6:
When dividing 857 by 431, we get 1 with a remainder of 426.
Use 1 as the next digit of our solution. 
Result so far: 741.0
Deduct 431 from 857 and we're left with 426.
Append the next digit (6) from the dividend to 426 and continue with: 4266 / 431

Advancing to step 7:
4266 divided by 431 is 9 with a remainder of 387.
Put 9 as the next digit of the answer. 
Result so far: 7419.0
The remainder is 387 after subtracting 3879 from 4266.
Append the next digit (8) from the dividend to 387 and continue with: 3878 / 431

Step 8:
The number 431 fits into 3878 8 times, leaving a remainder of 430.
The next digit of our result is 8. 
Result so far: 74198.0
If we subtract 3448 from 3878, we get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 9:
The number 431 fits into 4300 9 times, leaving a remainder of 421.
The number 9 becomes the next digit in our result. 
Result so far: 74198.9
If we subtract 3879 from 4300, we get 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Step 10:
The number 431 fits into 4210 9 times, leaving a remainder of 331.
Write down 9 as next digit of the result. 
Result so far: 74198.99
Deduct 3879 from 4210 and we're left with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

After the division, we end up with 74198.99 and a remainder of 0.331.
