90231095 ÷ 891 
We want to figure out the number of times 90231095 can be divided by 891.

On to step 1:
When dividing 9 by 891, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 891

Going ahead to step 2:
When dividing 90 by 891, we get 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Append the next digit (2) from the dividend to 90 and continue with: 902 / 891

Let's proceed to step 3:
891 can be fit into 902 1 times, resulting in a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 891 from 902 and we're left with 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 891

Going ahead to step 4:
When dividing 113 by 891, we get 0 with a remainder of 113.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 113 leaves us with 113.
Fetch the next digit (1) from the dividend, attach it to 113 and continue: 1131 / 891

Step 5:
When dividing 1131 by 891, we get 1 with a remainder of 240.
Put 1 as the next digit of the answer. 
Result so far: 101.0
If we subtract 891 from 1131, we get 240.
Take the next digit (0) from the dividend and append it to 240, then repeat: 2400 / 891

Going ahead to step 6:
891 goes into 2400 2 times with a remainder of 618.
The number 2 becomes the next digit in our result. 
Result so far: 1012.0
The remainder is 618 after subtracting 1782 from 2400.
Append the next digit (9) from the dividend to 618 and continue with: 6189 / 891

Advancing to step 7:
When dividing 6189 by 891, we get 6 with a remainder of 843.
Use 6 as the next digit of our solution. 
Result so far: 10126.0
If we subtract 5346 from 6189, we get 843.
Fetch the next digit (5) from the dividend, attach it to 843 and continue: 8435 / 891

Moving on to step 8:
891 goes into 8435 9 times with a remainder of 416.
The number 9 becomes the next digit in our result. 
Result so far: 101269.0
If we subtract 8019 from 8435, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 9:
4160 divided by 891 is 4 with a remainder of 596.
The number 4 becomes the next digit in our result. 
Result so far: 101269.4
Subtract 3564 from 4160 to get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

On to step 10:
5960 divided by 891 is 6 with a remainder of 614.
Put 6 as the next digit of the answer. 
Result so far: 101269.46
If we subtract 5346 from 5960, we get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Advancing to step 11:
When dividing 6140 by 891, we get 6 with a remainder of 794.
Put 6 as the next digit of the answer. 
Result so far: 101269.466
Deduct 5346 from 6140 and we're left with 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Our division results in 101269.466 with a remaining 0.0794.
