We look at the division of 89033390 by 91 
We want to divide 89033390 by 91.

On to step 1:
91 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 91

Going ahead to step 2:
If we divide 89 by 91, we get 0 and a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 89 to get 89.
Grab the next digit (0) from the dividend, add it to 89, then carry on: 890 / 91

Going ahead to step 3:
The number 91 fits into 890 9 times, leaving a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 819 from 890 leaves us with 71.
Take the next digit (3) from the dividend and append it to 71, then repeat: 713 / 91

Advancing to step 4:
When dividing 713 by 91, we get 7 with a remainder of 76.
The next digit of our result is 7. 
Result so far: 97.0
Subtracting 637 from 713 leaves us with 76.
Include the next digit (3) from the dividend after 76, then repeat: 763 / 91

Let's proceed to step 5:
If we divide 763 by 91, we get 8 and a remainder of 35.
Put 8 as the next digit of the answer. 
Result so far: 978.0
Deduct 728 from 763 and we're left with 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 91

Step 6:
The number 91 fits into 353 3 times, leaving a remainder of 80.
Use 3 as the next digit of our solution. 
Result so far: 9783.0
Subtract 273 from 353 to get 80.
Include the next digit (9) from the dividend after 80, then repeat: 809 / 91

Step 7:
If we divide 809 by 91, we get 8 and a remainder of 81.
The number 8 becomes the next digit in our result. 
Result so far: 97838.0
Deduct 728 from 809 and we're left with 81.
Grab the next digit (0) from the dividend, add it to 81, then carry on: 810 / 91

On to step 8:
91 can be fit into 810 8 times, resulting in a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 978388.0
The remainder is 82 after subtracting 728 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 9:
91 can be fit into 820 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 978388.9
The remainder is 1 after subtracting 819 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
The number 91 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 978388.9
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
The number 91 fits into 100 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 978388.901
Subtract 91 from 100 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 12:
91 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 978388.901
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 13:
91 can be fit into 900 9 times, resulting in a remainder of 81.
Use 9 as the next digit of our solution. 
Result so far: 978388.90109
Deduct 819 from 900 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 14:
91 can be fit into 810 8 times, resulting in a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 978388.901098
If we take 728 away from 810, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 15:
820 divided by 91 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 978388.9010989
The remainder is 1 after subtracting 819 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 16:
91 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 978388.9010989
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 978388.9010989 with a balance of 1e-08.
