We're dividing 631213 by 77 
Our goal is to divide 631213 by 77.

Let's proceed to step 1:
77 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 77

Advancing to step 2:
When dividing 63 by 77, we get 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Bring next digit (1) of the dividend behind the 63 and repeat the process: 631 / 77

Let's proceed to step 3:
77 can be fit into 631 8 times, resulting in a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 616 from 631, we get 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 77

Moving on to step 4:
77 can be fit into 152 1 times, resulting in a remainder of 75.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Subtracting 77 from 152 leaves us with 75.
Append the next digit (1) from the dividend to 75 and continue with: 751 / 77

Advancing to step 5:
77 goes into 751 9 times with a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 819.0
Subtracting 693 from 751 leaves us with 58.
Fetch the next digit (3) from the dividend, attach it to 58 and continue: 583 / 77

Going ahead to step 6:
The number 77 fits into 583 7 times, leaving a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 8197.0
If we subtract 539 from 583, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
440 divided by 77 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 8197.5
Subtract 385 from 440 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 8:
77 goes into 550 7 times with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 8197.57
The remainder is 11 after subtracting 539 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
110 divided by 77 is 1 with a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 8197.571
Subtracting 77 from 110 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 10:
If we divide 330 by 77, we get 4 and a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 8197.5714
If we subtract 308 from 330, 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.

Going ahead to step 11:
If we divide 220 by 77, we get 2 and a remainder of 66.
The next digit of our result is 2. 
Result so far: 8197.57142
If we take 154 away from 220, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 12:
The number 77 fits into 660 8 times, leaving a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 8197.571428
If we take 616 away from 660, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
When dividing 440 by 77, we get 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 8197.5714285
The remainder is 55 after subtracting 385 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 14:
If we divide 550 by 77, we get 7 and a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 8197.57142857
The remainder is 11 after subtracting 539 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 8197.57142857 and a remainder of 1.1e-08.
