Let's divide 81095591 by 891
We want to figure out the number of times 81095591 can be divided by 891.

Let's proceed to step 1:
8 divided by 891 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 891

Advancing to step 2:
If we divide 81 by 891, we get 0 and a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Append the next digit (0) from the dividend to 81 and continue with: 810 / 891

Advancing to step 3:
891 goes into 810 0 times with a remainder of 810.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 810 leaves us with 810.
Include the next digit (9) from the dividend after 810, then repeat: 8109 / 891

Step 4:
When dividing 8109 by 891, we get 9 with a remainder of 90.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 8019 away from 8109, we end up with 90.
Take the next digit (5) from the dividend and append it to 90, then repeat: 905 / 891

Advancing to step 5:
When dividing 905 by 891, we get 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 91.0
If we subtract 891 from 905, we get 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 891

Let's proceed to step 6:
If we divide 145 by 891, we get 0 and a remainder of 145.
The number 0 becomes the next digit in our result. 
Result so far: 910.0
Subtracting 0 from 145 leaves us with 145.
Bring next digit (9) of the dividend behind the 145 and repeat the process: 1459 / 891

On to step 7:
The number 891 fits into 1459 1 times, leaving a remainder of 568.
Record the quotient 1 as the next digit in the result. 
Result so far: 9101.0
Subtracting 891 from 1459 leaves us with 568.
Bring next digit (1) of the dividend behind the 568 and repeat the process: 5681 / 891

On to step 8:
If we divide 5681 by 891, we get 6 and a remainder of 335.
The next digit of our result is 6. 
Result so far: 91016.0
The remainder is 335 after subtracting 5346 from 5681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

On to step 9:
3350 divided by 891 is 3 with a remainder of 677.
Record the quotient 3 as the next digit in the result. 
Result so far: 91016.3
Subtracting 2673 from 3350 leaves us with 677.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

Going ahead to step 10:
If we divide 6770 by 891, we get 7 and a remainder of 533.
Record the quotient 7 as the next digit in the result. 
Result so far: 91016.37
Deduct 6237 from 6770 and we're left with 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Moving on to step 11:
5330 divided by 891 is 5 with a remainder of 875.
Write down 5 as next digit of the result. 
Result so far: 91016.375
If we subtract 4455 from 5330, we get 875.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8750, and continue the process.

Step 12:
If we divide 8750 by 891, we get 9 and a remainder of 731.
Write down 9 as next digit of the result. 
Result so far: 91016.3759
The remainder is 731 after subtracting 8019 from 8750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

Advancing to step 13:
When dividing 7310 by 891, we get 8 with a remainder of 182.
Use 8 as the next digit of our solution. 
Result so far: 91016.37598
If we subtract 7128 from 7310, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Advancing to step 14:
1820 divided by 891 is 2 with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 91016.375982
If we subtract 1782 from 1820, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 15:
When dividing 380 by 891, we get 0 with a remainder of 380.
Write down 0 as next digit of the result. 
Result so far: 91016.375982
Subtracting 0 from 380 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 16:
3800 divided by 891 is 4 with a remainder of 236.
Record the quotient 4 as the next digit in the result. 
Result so far: 91016.37598204
Subtract 3564 from 3800 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Our division results in 91016.37598204 with a remaining 2.36e-07.
