We're dividing 631988 by 77 
We want to divide 631988 by 77.

Step 1:
77 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 77

Moving on to step 2:
77 goes into 63 0 times with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Include the next digit (1) from the dividend after 63, then repeat: 631 / 77

On to step 3:
When dividing 631 by 77, we get 8 with a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 616 from 631 and we're left with 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 77

On to step 4:
If we divide 159 by 77, we get 2 and a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 82.0
Subtract 154 from 159 to get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 77

On to step 5:
58 divided by 77 is 0 with a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 820.0
If we take 0 away from 58, we end up with 58.
Take the next digit (8) from the dividend and append it to 58, then repeat: 588 / 77

On to step 6:
The number 77 fits into 588 7 times, leaving a remainder of 49.
Write down 7 as next digit of the result. 
Result so far: 8207.0
If we take 539 away from 588, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
490 divided by 77 is 6 with a remainder of 28.
The next digit of our result is 6. 
Result so far: 8207.6
The remainder is 28 after subtracting 462 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
If we divide 280 by 77, we get 3 and a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 8207.63
Subtract 231 from 280 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 9:
The number 77 fits into 490 6 times, leaving a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 8207.636
Subtract 462 from 490 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
77 goes into 280 3 times with a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 8207.6363
If we take 231 away from 280, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 11:
When dividing 490 by 77, we get 6 with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 8207.63636
Subtracting 462 from 490 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 12:
77 can be fit into 280 3 times, resulting in a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 8207.636363
If we subtract 231 from 280, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 13:
490 divided by 77 is 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 8207.6363636
The remainder is 28 after subtracting 462 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 14:
77 can be fit into 280 3 times, resulting in a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 8207.63636363
If we subtract 231 from 280, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Our division results in 8207.63636363 with a remaining 4.9e-08.
