63621 ÷ 77 
We're looking to find how many times 77 goes into 63621.

Advancing to step 1:
6 divided by 77 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 77

Let's proceed to step 2:
The number 77 fits into 63 0 times, leaving a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Fetch the next digit (6) from the dividend, attach it to 63 and continue: 636 / 77

Advancing to step 3:
The number 77 fits into 636 8 times, leaving a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 616 away from 636, we end up with 20.
Fetch the next digit (2) from the dividend, attach it to 20 and continue: 202 / 77

Going ahead to step 4:
77 goes into 202 2 times with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 82.0
If we take 154 away from 202, we end up with 48.
Append the next digit (1) from the dividend to 48 and continue with: 481 / 77

Step 5:
When dividing 481 by 77, we get 6 with a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 826.0
Deduct 462 from 481 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 6:
The number 77 fits into 190 2 times, leaving a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 826.2
Subtracting 154 from 190 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
77 can be fit into 360 4 times, resulting in a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 826.24
The remainder is 52 after subtracting 308 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 8:
77 goes into 520 6 times with a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 826.246
If we subtract 462 from 520, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 9:
77 can be fit into 580 7 times, resulting in a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 826.2467
If we take 539 away from 580, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 10:
The number 77 fits into 410 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 826.24675
If we subtract 385 from 410, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
77 goes into 250 3 times with a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 826.246753
If we subtract 231 from 250, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 12:
The number 77 fits into 190 2 times, leaving a remainder of 36.
The next digit of our result is 2. 
Result so far: 826.2467532
If we subtract 154 from 190, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
The number 77 fits into 360 4 times, leaving a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 826.24675324
Subtracting 308 from 360 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 826.24675324, and the remainder is 5.2e-08.
