We divide 621886 by 77
We're looking to find how many times 77 goes into 621886.

Step 1:
77 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 77

Step 2:
If we divide 62 by 77, we get 0 and a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 62 after subtracting 0 from 62.
Grab the next digit (1) from the dividend, add it to 62, then carry on: 621 / 77

On to step 3:
If we divide 621 by 77, we get 8 and a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 616 from 621 to get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 77

Advancing to step 4:
If we divide 58 by 77, we get 0 and a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 80.0
If we subtract 0 from 58, we get 58.
Grab the next digit (8) from the dividend, add it to 58, then carry on: 588 / 77

On to step 5:
The number 77 fits into 588 7 times, leaving a remainder of 49.
The next digit of our result is 7. 
Result so far: 807.0
Subtracting 539 from 588 leaves us with 49.
Append the next digit (6) from the dividend to 49 and continue with: 496 / 77

Step 6:
77 goes into 496 6 times with a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 8076.0
If we take 462 away from 496, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
77 can be fit into 340 4 times, resulting in a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 8076.4
Subtracting 308 from 340 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 8:
320 divided by 77 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 8076.44
If we subtract 308 from 320, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 8076.44, and the remainder is 0.012.
