Let's divide 312630 by 76
Our goal is to divide 312630 by 76.

Going ahead to step 1:
The number 76 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.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 76

Going ahead to step 2:
76 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 (2) of the dividend behind the 31 and repeat the process: 312 / 76

On to step 3:
The number 76 fits into 312 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 304 away from 312, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 76

On to step 4:
If we divide 86 by 76, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 41.0
Subtracting 76 from 86 leaves us with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 76

Moving on to step 5:
The number 76 fits into 103 1 times, leaving a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 411.0
Subtracting 76 from 103 leaves us with 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 76

Moving on to step 6:
76 goes into 270 3 times with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 4113.0
Subtracting 228 from 270 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 7:
420 divided by 76 is 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 4113.5
If we subtract 380 from 420, we get 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 8:
400 divided by 76 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 4113.55
Deduct 380 from 400 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 4113.55, and the remainder is 0.02.
