We divide 63664008 by 77
We want to figure out the number of times 63664008 can be divided by 77.

On to step 1:
When dividing 6 by 77, we get 0 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.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 77

Advancing to step 2:
If we divide 63 by 77, we get 0 and a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Take the next digit (6) from the dividend and append it to 63, then repeat: 636 / 77

On to step 3:
When dividing 636 by 77, we get 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 616 away from 636, we end up with 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 77

Moving on to step 4:
The number 77 fits into 206 2 times, leaving a remainder of 52.
The next digit of our result is 2. 
Result so far: 82.0
The remainder is 52 after subtracting 154 from 206.
Include the next digit (4) from the dividend after 52, then repeat: 524 / 77

Step 5:
The number 77 fits into 524 6 times, leaving a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 826.0
Subtract 462 from 524 to get 62.
Grab the next digit (0) from the dividend, add it to 62, then carry on: 620 / 77

Advancing to step 6:
77 can be fit into 620 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 8268.0
If we subtract 616 from 620, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 77

Advancing to step 7:
77 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 82680.0
If we subtract 0 from 40, we get 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 77

On to step 8:
77 can be fit into 408 5 times, resulting in a remainder of 23.
Use 5 as the next digit of our solution. 
Result so far: 826805.0
The remainder is 23 after subtracting 385 from 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 9:
77 goes into 230 2 times with a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 826805.2
If we take 154 away from 230, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
The number 77 fits into 760 9 times, leaving a remainder of 67.
Use 9 as the next digit of our solution. 
Result so far: 826805.29
If we subtract 693 from 760, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 11:
77 can be fit into 670 8 times, resulting in a remainder of 54.
The next digit of our result is 8. 
Result so far: 826805.298
If we subtract 616 from 670, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 12:
77 goes into 540 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 826805.2987
Subtracting 539 from 540 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 13:
If we divide 10 by 77, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 826805.2987
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
77 can be fit into 100 1 times, resulting in a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 826805.298701
Subtracting 77 from 100 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 15:
77 can be fit into 230 2 times, resulting in a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 826805.2987012
Subtracting 154 from 230 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 16:
When dividing 760 by 77, we get 9 with a remainder of 67.
Use 9 as the next digit of our solution. 
Result so far: 826805.29870129
Subtracting 693 from 760 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Our division results in 826805.29870129 with a remaining 6.7e-08.
