90080628 ÷ 91 
We want to divide 90080628 by 91.

On to step 1:
91 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 91

Let's proceed to step 2:
91 goes into 90 0 times with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Grab the next digit (0) from the dividend, add it to 90, then carry on: 900 / 91

Moving on to step 3:
The number 91 fits into 900 9 times, leaving a remainder of 81.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 819 from 900 to get 81.
Append the next digit (8) from the dividend to 81 and continue with: 818 / 91

Let's proceed to step 4:
The number 91 fits into 818 8 times, leaving a remainder of 90.
Put 8 as the next digit of the answer. 
Result so far: 98.0
Deduct 728 from 818 and we're left with 90.
Include the next digit (0) from the dividend after 90, then repeat: 900 / 91

Advancing to step 5:
The number 91 fits into 900 9 times, leaving a remainder of 81.
Put 9 as the next digit of the answer. 
Result so far: 989.0
If we subtract 819 from 900, we get 81.
Take the next digit (6) from the dividend and append it to 81, then repeat: 816 / 91

Let's proceed to step 6:
91 goes into 816 8 times with a remainder of 88.
The next digit of our result is 8. 
Result so far: 9898.0
If we take 728 away from 816, we end up with 88.
Take the next digit (2) from the dividend and append it to 88, then repeat: 882 / 91

Going ahead to step 7:
91 can be fit into 882 9 times, resulting in a remainder of 63.
Write down 9 as next digit of the result. 
Result so far: 98989.0
Subtracting 819 from 882 leaves us with 63.
Take the next digit (8) from the dividend and append it to 63, then repeat: 638 / 91

Let's proceed to step 8:
If we divide 638 by 91, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 989897.0
Deduct 637 from 638 and we're left with 1.
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 9:
91 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 989897.0
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.

Advancing to step 10:
100 divided by 91 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 989897.01
If we take 91 away from 100, we end up with 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 11:
91 goes into 90 0 times with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 989897.01
The remainder is 90 after subtracting 0 from 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 12:
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: 989897.0109
Subtract 819 from 900 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 13:
If we divide 810 by 91, we get 8 and a remainder of 82.
Use 8 as the next digit of our solution. 
Result so far: 989897.01098
Deduct 728 from 810 and we're left 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.

On to step 14:
When dividing 820 by 91, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 989897.010989
If we subtract 819 from 820, we get 1.
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 15:
If we divide 10 by 91, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 989897.010989
If we take 0 away from 10, we end up 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.

Advancing to step 16:
91 goes into 100 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 989897.01098901
Deduct 91 from 100 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 989897.01098901 with a balance of 9e-09.
