We look at the division of 77644250 by 877 
We're looking to find how many times 877 goes into 77644250.

Going ahead to step 1:
877 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 877

Let's proceed to step 2:
The number 877 fits into 77 0 times, leaving a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Fetch the next digit (6) from the dividend, attach it to 77 and continue: 776 / 877

Advancing to step 3:
If we divide 776 by 877, we get 0 and a remainder of 776.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 776, we get 776.
Take the next digit (4) from the dividend and append it to 776, then repeat: 7764 / 877

On to step 4:
If we divide 7764 by 877, we get 8 and a remainder of 748.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 748 after subtracting 7016 from 7764.
Append the next digit (4) from the dividend to 748 and continue with: 7484 / 877

Advancing to step 5:
877 can be fit into 7484 8 times, resulting in a remainder of 468.
Write down 8 as next digit of the result. 
Result so far: 88.0
Subtracting 7016 from 7484 leaves us with 468.
Include the next digit (2) from the dividend after 468, then repeat: 4682 / 877

Let's proceed to step 6:
The number 877 fits into 4682 5 times, leaving a remainder of 297.
The number 5 becomes the next digit in our result. 
Result so far: 885.0
The remainder is 297 after subtracting 4385 from 4682.
Include the next digit (5) from the dividend after 297, then repeat: 2975 / 877

Going ahead to step 7:
The number 877 fits into 2975 3 times, leaving a remainder of 344.
Record the quotient 3 as the next digit in the result. 
Result so far: 8853.0
If we subtract 2631 from 2975, we get 344.
Take the next digit (0) from the dividend and append it to 344, then repeat: 3440 / 877

Moving on to step 8:
If we divide 3440 by 877, we get 3 and a remainder of 809.
Use 3 as the next digit of our solution. 
Result so far: 88533.0
Subtract 2631 from 3440 to get 809.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8090, and continue the process.

Advancing to step 9:
The number 877 fits into 8090 9 times, leaving a remainder of 197.
Put 9 as the next digit of the answer. 
Result so far: 88533.9
Subtract 7893 from 8090 to get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Going ahead to step 10:
877 can be fit into 1970 2 times, resulting in a remainder of 216.
Record the quotient 2 as the next digit in the result. 
Result so far: 88533.92
Subtracting 1754 from 1970 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 11:
877 goes into 2160 2 times with a remainder of 406.
Put 2 as the next digit of the answer. 
Result so far: 88533.922
Subtracting 1754 from 2160 leaves us with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

The final outcome is 88533.922, with a leftover of 0.0406.
