We divide 81093745 by 891
Let's see how many times 891 fits into 81093745.

Going ahead to step 1:
If we divide 8 by 891, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 891

Moving on to step 2:
891 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Append the next digit (0) from the dividend to 81 and continue with: 810 / 891

Advancing to step 3:
The number 891 fits into 810 0 times, leaving a remainder of 810.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 810 to get 810.
Grab the next digit (9) from the dividend, add it to 810, then carry on: 8109 / 891

On to step 4:
8109 divided by 891 is 9 with a remainder of 90.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 8019 from 8109 to get 90.
Grab the next digit (3) from the dividend, add it to 90, then carry on: 903 / 891

Advancing to step 5:
903 divided by 891 is 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 91.0
If we take 891 away from 903, we end up with 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 891

On to step 6:
When dividing 127 by 891, we get 0 with a remainder of 127.
The number 0 becomes the next digit in our result. 
Result so far: 910.0
Subtract 0 from 127 to get 127.
Grab the next digit (4) from the dividend, add it to 127, then carry on: 1274 / 891

Step 7:
891 can be fit into 1274 1 times, resulting in a remainder of 383.
The next digit of our result is 1. 
Result so far: 9101.0
If we take 891 away from 1274, we end up with 383.
Bring next digit (5) of the dividend behind the 383 and repeat the process: 3835 / 891

Moving on to step 8:
When dividing 3835 by 891, we get 4 with a remainder of 271.
The next digit of our result is 4. 
Result so far: 91014.0
If we subtract 3564 from 3835, we get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Step 9:
The number 891 fits into 2710 3 times, leaving a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 91014.3
If we take 2673 away from 2710, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 10:
891 can be fit into 370 0 times, resulting in a remainder of 370.
The number 0 becomes the next digit in our result. 
Result so far: 91014.3
Subtract 0 from 370 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 11:
If we divide 3700 by 891, we get 4 and a remainder of 136.
Use 4 as the next digit of our solution. 
Result so far: 91014.304
If we take 3564 away from 3700, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 12:
The number 891 fits into 1360 1 times, leaving a remainder of 469.
Write down 1 as next digit of the result. 
Result so far: 91014.3041
Subtracting 891 from 1360 leaves us with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Going ahead to step 13:
891 can be fit into 4690 5 times, resulting in a remainder of 235.
Record the quotient 5 as the next digit in the result. 
Result so far: 91014.30415
Subtract 4455 from 4690 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

On to step 14:
The number 891 fits into 2350 2 times, leaving a remainder of 568.
Record the quotient 2 as the next digit in the result. 
Result so far: 91014.304152
Deduct 1782 from 2350 and we're left with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Let's proceed to step 15:
When dividing 5680 by 891, we get 6 with a remainder of 334.
Put 6 as the next digit of the answer. 
Result so far: 91014.3041526
Subtracting 5346 from 5680 leaves us with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Advancing to step 16:
3340 divided by 891 is 3 with a remainder of 667.
The next digit of our result is 3. 
Result so far: 91014.30415263
Subtract 2673 from 3340 to get 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

The final outcome is 91014.30415263, with a leftover of 6.67e-07.
