We look at the division of 3131599 by 612 
Our goal is to divide 3131599 by 612.

Going ahead to step 1:
When dividing 3 by 612, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 612

Step 2:
31 divided by 612 is 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 612

Step 3:
When dividing 313 by 612, we get 0 with a remainder of 313.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 313 to get 313.
Bring next digit (1) of the dividend behind the 313 and repeat the process: 3131 / 612

Let's proceed to step 4:
If we divide 3131 by 612, we get 5 and a remainder of 71.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 3060 from 3131, we get 71.
Grab the next digit (5) from the dividend, add it to 71, then carry on: 715 / 612

On to step 5:
715 divided by 612 is 1 with a remainder of 103.
Use 1 as the next digit of our solution. 
Result so far: 51.0
If we take 612 away from 715, we end up with 103.
Bring next digit (9) of the dividend behind the 103 and repeat the process: 1039 / 612

On to step 6:
612 goes into 1039 1 times with a remainder of 427.
Write down 1 as next digit of the result. 
Result so far: 511.0
If we subtract 612 from 1039, we get 427.
Append the next digit (9) from the dividend to 427 and continue with: 4279 / 612

Step 7:
4279 divided by 612 is 6 with a remainder of 607.
The number 6 becomes the next digit in our result. 
Result so far: 5116.0
If we take 3672 away from 4279, we end up with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Moving on to step 8:
612 can be fit into 6070 9 times, resulting in a remainder of 562.
Put 9 as the next digit of the answer. 
Result so far: 5116.9
Subtracting 5508 from 6070 leaves us with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Step 9:
The number 612 fits into 5620 9 times, leaving a remainder of 112.
Use 9 as the next digit of our solution. 
Result so far: 5116.99
Subtract 5508 from 5620 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The quotient of the division is 5116.99, and the remainder is 0.112.
