We look at the division of 63901556 by 777 
We want to figure out the number of times 63901556 can be divided by 777.

Advancing to step 1:
The number 777 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 777

On to step 2:
The number 777 fits into 63 0 times, leaving a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 777

Let's proceed to step 3:
When dividing 639 by 777, we get 0 with a remainder of 639.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 639 leaves us with 639.
Append the next digit (0) from the dividend to 639 and continue with: 6390 / 777

Going ahead to step 4:
777 goes into 6390 8 times with a remainder of 174.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 6216 from 6390 to get 174.
Take the next digit (1) from the dividend and append it to 174, then repeat: 1741 / 777

Step 5:
1741 divided by 777 is 2 with a remainder of 187.
Put 2 as the next digit of the answer. 
Result so far: 82.0
The remainder is 187 after subtracting 1554 from 1741.
Take the next digit (5) from the dividend and append it to 187, then repeat: 1875 / 777

On to step 6:
The number 777 fits into 1875 2 times, leaving a remainder of 321.
Use 2 as the next digit of our solution. 
Result so far: 822.0
The remainder is 321 after subtracting 1554 from 1875.
Fetch the next digit (5) from the dividend, attach it to 321 and continue: 3215 / 777

Let's proceed to step 7:
The number 777 fits into 3215 4 times, leaving a remainder of 107.
The number 4 becomes the next digit in our result. 
Result so far: 8224.0
Subtract 3108 from 3215 to get 107.
Fetch the next digit (6) from the dividend, attach it to 107 and continue: 1076 / 777

Going ahead to step 8:
777 can be fit into 1076 1 times, resulting in a remainder of 299.
Use 1 as the next digit of our solution. 
Result so far: 82241.0
Subtract 777 from 1076 to get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

On to step 9:
777 can be fit into 2990 3 times, resulting in a remainder of 659.
Record the quotient 3 as the next digit in the result. 
Result so far: 82241.3
If we take 2331 away from 2990, we end up with 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

Step 10:
If we divide 6590 by 777, we get 8 and a remainder of 374.
Record the quotient 8 as the next digit in the result. 
Result so far: 82241.38
Deduct 6216 from 6590 and we're left with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 11:
When dividing 3740 by 777, we get 4 with a remainder of 632.
The next digit of our result is 4. 
Result so far: 82241.384
The remainder is 632 after subtracting 3108 from 3740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Moving on to step 12:
When dividing 6320 by 777, we get 8 with a remainder of 104.
The number 8 becomes the next digit in our result. 
Result so far: 82241.3848
If we take 6216 away from 6320, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 13:
777 can be fit into 1040 1 times, resulting in a remainder of 263.
The number 1 becomes the next digit in our result. 
Result so far: 82241.38481
The remainder is 263 after subtracting 777 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Let's proceed to step 14:
If we divide 2630 by 777, we get 3 and a remainder of 299.
Write down 3 as next digit of the result. 
Result so far: 82241.384813
Subtracting 2331 from 2630 leaves us with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Moving on to step 15:
777 can be fit into 2990 3 times, resulting in a remainder of 659.
Record the quotient 3 as the next digit in the result. 
Result so far: 82241.3848133
The remainder is 659 after subtracting 2331 from 2990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

The final result is 82241.3848133 with a remainder of 6.59e-06.
