We look at the division of 31612480 by 42 
Our goal is to divide 31612480 by 42.

Going ahead to step 1:
The number 42 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 42

Step 2:
31 divided by 42 is 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Grab the next digit (6) from the dividend, add it to 31, then carry on: 316 / 42

Going ahead to step 3:
42 goes into 316 7 times with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 294 away from 316, we end up with 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 42

Step 4:
When dividing 221 by 42, we get 5 with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
Subtracting 210 from 221 leaves us with 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 42

Step 5:
42 can be fit into 112 2 times, resulting in a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 752.0
Subtract 84 from 112 to get 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 42

On to step 6:
42 goes into 284 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 7526.0
If we subtract 252 from 284, we get 32.
Include the next digit (8) from the dividend after 32, then repeat: 328 / 42

Going ahead to step 7:
42 can be fit into 328 7 times, resulting in a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 75267.0
Deduct 294 from 328 and we're left with 34.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 42

Let's proceed to step 8:
340 divided by 42 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 752678.0
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
42 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 752678.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 752678.09
The remainder is 22 after subtracting 378 from 400.
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 11:
If we divide 220 by 42, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 752678.095
Subtracting 210 from 220 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
If we divide 100 by 42, we get 2 and a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 752678.0952
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
If we divide 160 by 42, we get 3 and a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 752678.09523
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 14:
42 can be fit into 340 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 752678.095238
Deduct 336 from 340 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 15:
When dividing 40 by 42, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 752678.095238
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 16:
400 divided by 42 is 9 with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 752678.09523809
If we subtract 378 from 400, we 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.

Our division results in 752678.09523809 with a remaining 2.2e-08.
