We look at the division of 31920797 by 84 
We're looking to find how many times 84 goes into 31920797.

Advancing to step 1:
84 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 84

On to step 2:
84 can be fit into 31 0 times, resulting in a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Bring next digit (9) of the dividend behind the 31 and repeat the process: 319 / 84

Moving on to step 3:
If we divide 319 by 84, we get 3 and a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 67 after subtracting 252 from 319.
Grab the next digit (2) from the dividend, add it to 67, then carry on: 672 / 84

Step 4:
The number 84 fits into 672 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Subtracting 672 from 672 leaves us with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 84

Step 5:
84 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 380.0
The remainder is 0 after subtracting 0 from 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 84

On to step 6:
84 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 3800.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 84

Let's proceed to step 7:
When dividing 79 by 84, we get 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 38000.0
Deduct 0 from 79 and we're left with 79.
Take the next digit (7) from the dividend and append it to 79, then repeat: 797 / 84

Step 8:
84 goes into 797 9 times with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 380009.0
Subtracting 756 from 797 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 9:
84 goes into 410 4 times with a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 380009.4
Subtract 336 from 410 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 10:
If we divide 740 by 84, we get 8 and a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 380009.48
Subtract 672 from 740 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 11:
84 can be fit into 680 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 380009.488
The remainder is 8 after subtracting 672 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 380009.488 with a remaining 0.0008.
