We're dividing 63877069 by 877 
We want to figure out the number of times 63877069 can be divided by 877.

Moving on to step 1:
6 divided by 877 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 877

Let's proceed to step 2:
877 goes into 63 0 times with 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.
Append the next digit (8) from the dividend to 63 and continue with: 638 / 877

On to step 3:
638 divided by 877 is 0 with a remainder of 638.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 638, we get 638.
Append the next digit (7) from the dividend to 638 and continue with: 6387 / 877

Step 4:
877 can be fit into 6387 7 times, resulting in a remainder of 248.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 6139 from 6387 and we're left with 248.
Include the next digit (7) from the dividend after 248, then repeat: 2487 / 877

On to step 5:
The number 877 fits into 2487 2 times, leaving a remainder of 733.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Subtract 1754 from 2487 to get 733.
Grab the next digit (0) from the dividend, add it to 733, then carry on: 7330 / 877

Moving on to step 6:
If we divide 7330 by 877, we get 8 and a remainder of 314.
Write down 8 as next digit of the result. 
Result so far: 728.0
Subtract 7016 from 7330 to get 314.
Include the next digit (6) from the dividend after 314, then repeat: 3146 / 877

Moving on to step 7:
877 goes into 3146 3 times with a remainder of 515.
Record the quotient 3 as the next digit in the result. 
Result so far: 7283.0
If we take 2631 away from 3146, we end up with 515.
Include the next digit (9) from the dividend after 515, then repeat: 5159 / 877

Step 8:
When dividing 5159 by 877, we get 5 with a remainder of 774.
Use 5 as the next digit of our solution. 
Result so far: 72835.0
Subtracting 4385 from 5159 leaves us with 774.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

On to step 9:
When dividing 7740 by 877, we get 8 with a remainder of 724.
Put 8 as the next digit of the answer. 
Result so far: 72835.8
Deduct 7016 from 7740 and we're left with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

On to step 10:
877 goes into 7240 8 times with a remainder of 224.
Record the quotient 8 as the next digit in the result. 
Result so far: 72835.88
The remainder is 224 after subtracting 7016 from 7240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

The quotient of the division is 72835.88, and the remainder is 0.224.
