We look at the division of 903439 by 91 
Our goal is to divide 903439 by 91.

On to step 1:
When dividing 9 by 91, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 91

On to step 2:
The number 91 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Fetch the next digit (3) from the dividend, attach it to 90 and continue: 903 / 91

On to step 3:
903 divided by 91 is 9 with a remainder of 84.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 819 from 903 leaves us with 84.
Grab the next digit (4) from the dividend, add it to 84, then carry on: 844 / 91

On to step 4:
The number 91 fits into 844 9 times, leaving a remainder of 25.
The next digit of our result is 9. 
Result so far: 99.0
Subtract 819 from 844 to get 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 91

Going ahead to step 5:
253 divided by 91 is 2 with a remainder of 71.
The next digit of our result is 2. 
Result so far: 992.0
If we take 182 away from 253, we end up with 71.
Include the next digit (9) from the dividend after 71, then repeat: 719 / 91

On to step 6:
If we divide 719 by 91, we get 7 and a remainder of 82.
Write down 7 as next digit of the result. 
Result so far: 9927.0
The remainder is 82 after subtracting 637 from 719.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 7:
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: 9927.9
Subtract 819 from 820 to 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.

Moving on to step 8:
91 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 9927.9
Subtracting 0 from 10 leaves us 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.

Let's proceed to step 9:
91 goes into 100 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 9927.901
Subtracting 91 from 100 leaves us 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.

Step 10:
90 divided by 91 is 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 9927.901
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 11:
900 divided by 91 is 9 with a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 9927.90109
The remainder is 81 after subtracting 819 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 12:
The number 91 fits into 810 8 times, leaving a remainder of 82.
Use 8 as the next digit of our solution. 
Result so far: 9927.901098
Subtract 728 from 810 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 13:
When dividing 820 by 91, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 9927.9010989
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.

Moving on to step 14:
91 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 9927.9010989
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 9927.9010989, and the remainder is 1e-08.
