91891122 divided by 878 
We're looking to find how many times 878 goes into 91891122.

Going ahead to step 1:
878 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 878

Moving on to step 2:
878 goes into 91 0 times with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Take the next digit (8) from the dividend and append it to 91, then repeat: 918 / 878

Moving on to step 3:
When dividing 918 by 878, we get 1 with a remainder of 40.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 878 from 918 and we're left with 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 878

Let's proceed to step 4:
The number 878 fits into 409 0 times, leaving a remainder of 409.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 409 after subtracting 0 from 409.
Grab the next digit (1) from the dividend, add it to 409, then carry on: 4091 / 878

Step 5:
878 can be fit into 4091 4 times, resulting in a remainder of 579.
Use 4 as the next digit of our solution. 
Result so far: 104.0
Deduct 3512 from 4091 and we're left with 579.
Grab the next digit (1) from the dividend, add it to 579, then carry on: 5791 / 878

Step 6:
When dividing 5791 by 878, we get 6 with a remainder of 523.
Record the quotient 6 as the next digit in the result. 
Result so far: 1046.0
If we subtract 5268 from 5791, we get 523.
Take the next digit (2) from the dividend and append it to 523, then repeat: 5232 / 878

Step 7:
If we divide 5232 by 878, we get 5 and a remainder of 842.
Put 5 as the next digit of the answer. 
Result so far: 10465.0
Deduct 4390 from 5232 and we're left with 842.
Fetch the next digit (2) from the dividend, attach it to 842 and continue: 8422 / 878

On to step 8:
8422 divided by 878 is 9 with a remainder of 520.
The number 9 becomes the next digit in our result. 
Result so far: 104659.0
If we subtract 7902 from 8422, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 9:
When dividing 5200 by 878, we get 5 with a remainder of 810.
Use 5 as the next digit of our solution. 
Result so far: 104659.5
The remainder is 810 after subtracting 4390 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

On to step 10:
When dividing 8100 by 878, we get 9 with a remainder of 198.
Use 9 as the next digit of our solution. 
Result so far: 104659.59
If we subtract 7902 from 8100, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 11:
878 can be fit into 1980 2 times, resulting in a remainder of 224.
Record the quotient 2 as the next digit in the result. 
Result so far: 104659.592
Subtract 1756 from 1980 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 12:
The number 878 fits into 2240 2 times, leaving a remainder of 484.
The number 2 becomes the next digit in our result. 
Result so far: 104659.5922
If we subtract 1756 from 2240, we get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

In conclusion, the division gives 104659.5922 with a balance of 0.00484.
