Let's divide 88149921 by 877
Our goal is to divide 88149921 by 877.

Let's proceed to step 1:
8 divided by 877 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 877

On to step 2:
When dividing 88 by 877, we get 0 with a remainder of 88.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 88, we get 88.
Grab the next digit (1) from the dividend, add it to 88, then carry on: 881 / 877

Going ahead to step 3:
If we divide 881 by 877, we get 1 and a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 877 from 881 to get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 877

Moving on to step 4:
The number 877 fits into 44 0 times, leaving a remainder of 44.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 44, we get 44.
Grab the next digit (9) from the dividend, add it to 44, then carry on: 449 / 877

Step 5:
877 can be fit into 449 0 times, resulting in a remainder of 449.
Write down 0 as next digit of the result. 
Result so far: 100.0
Deduct 0 from 449 and we're left with 449.
Grab the next digit (9) from the dividend, add it to 449, then carry on: 4499 / 877

On to step 6:
877 can be fit into 4499 5 times, resulting in a remainder of 114.
Write down 5 as next digit of the result. 
Result so far: 1005.0
If we take 4385 away from 4499, we end up with 114.
Include the next digit (2) from the dividend after 114, then repeat: 1142 / 877

On to step 7:
If we divide 1142 by 877, we get 1 and a remainder of 265.
Record the quotient 1 as the next digit in the result. 
Result so far: 10051.0
Subtracting 877 from 1142 leaves us with 265.
Include the next digit (1) from the dividend after 265, then repeat: 2651 / 877

Let's proceed to step 8:
The number 877 fits into 2651 3 times, leaving a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 100513.0
Deduct 2631 from 2651 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
When dividing 200 by 877, we get 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 100513.0
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 10:
If we divide 2000 by 877, we get 2 and a remainder of 246.
The number 2 becomes the next digit in our result. 
Result so far: 100513.02
Subtracting 1754 from 2000 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 11:
2460 divided by 877 is 2 with a remainder of 706.
Record the quotient 2 as the next digit in the result. 
Result so far: 100513.022
If we subtract 1754 from 2460, we get 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

The final outcome is 100513.022, with a leftover of 0.0706.
