We look at the division of 98991517 by 878 
We're looking to find how many times 878 goes into 98991517.

Advancing to step 1:
9 divided by 878 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 878

On to step 2:
878 can be fit into 98 0 times, resulting in a remainder of 98.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 98, we end up with 98.
Take the next digit (9) from the dividend and append it to 98, then repeat: 989 / 878

Advancing to step 3:
878 goes into 989 1 times with a remainder of 111.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 878 from 989, we get 111.
Append the next digit (9) from the dividend to 111 and continue with: 1119 / 878

Moving on to step 4:
If we divide 1119 by 878, we get 1 and a remainder of 241.
The next digit of our result is 1. 
Result so far: 11.0
If we take 878 away from 1119, we end up with 241.
Fetch the next digit (1) from the dividend, attach it to 241 and continue: 2411 / 878

On to step 5:
The number 878 fits into 2411 2 times, leaving a remainder of 655.
Use 2 as the next digit of our solution. 
Result so far: 112.0
Subtract 1756 from 2411 to get 655.
Grab the next digit (5) from the dividend, add it to 655, then carry on: 6555 / 878

Let's proceed to step 6:
If we divide 6555 by 878, we get 7 and a remainder of 409.
Record the quotient 7 as the next digit in the result. 
Result so far: 1127.0
If we take 6146 away from 6555, we end up with 409.
Include the next digit (1) from the dividend after 409, then repeat: 4091 / 878

Advancing to step 7:
If we divide 4091 by 878, we get 4 and a remainder of 579.
Use 4 as the next digit of our solution. 
Result so far: 11274.0
Subtract 3512 from 4091 to get 579.
Include the next digit (7) from the dividend after 579, then repeat: 5797 / 878

Step 8:
The number 878 fits into 5797 6 times, leaving a remainder of 529.
Record the quotient 6 as the next digit in the result. 
Result so far: 112746.0
If we take 5268 away from 5797, we end up with 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Advancing to step 9:
878 goes into 5290 6 times with a remainder of 22.
The next digit of our result is 6. 
Result so far: 112746.6
The remainder is 22 after subtracting 5268 from 5290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
When dividing 220 by 878, we get 0 with a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 112746.6
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 11:
The number 878 fits into 2200 2 times, leaving a remainder of 444.
Write down 2 as next digit of the result. 
Result so far: 112746.602
If we take 1756 away from 2200, we end up with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Let's proceed to step 12:
878 goes into 4440 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 112746.6025
The remainder is 50 after subtracting 4390 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
The number 878 fits into 500 0 times, leaving a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 112746.6025
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 14:
878 goes into 5000 5 times with a remainder of 610.
The number 5 becomes the next digit in our result. 
Result so far: 112746.602505
Subtract 4390 from 5000 to get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

On to step 15:
878 can be fit into 6100 6 times, resulting in a remainder of 832.
Write down 6 as next digit of the result. 
Result so far: 112746.6025056
The remainder is 832 after subtracting 5268 from 6100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Moving on to step 16:
If we divide 8320 by 878, we get 9 and a remainder of 418.
The number 9 becomes the next digit in our result. 
Result so far: 112746.60250569
If we take 7902 away from 8320, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

The final outcome is 112746.60250569, with a leftover of 4.18e-07.
