We look at the division of 591601 by 91 
We're looking to find how many times 91 goes into 591601.

Step 1:
5 divided by 91 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 91

On to step 2:
If we divide 59 by 91, we get 0 and a remainder of 59.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 59 after subtracting 0 from 59.
Fetch the next digit (1) from the dividend, attach it to 59 and continue: 591 / 91

On to step 3:
When dividing 591 by 91, we get 6 with a remainder of 45.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 546 away from 591, we end up with 45.
Fetch the next digit (6) from the dividend, attach it to 45 and continue: 456 / 91

Let's proceed to step 4:
91 can be fit into 456 5 times, resulting in a remainder of 1.
The next digit of our result is 5. 
Result so far: 65.0
If we subtract 455 from 456, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 91

Step 5:
10 divided by 91 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 650.0
The remainder is 10 after subtracting 0 from 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 91

Let's proceed to step 6:
The number 91 fits into 101 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 6501.0
The remainder is 10 after subtracting 91 from 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
100 divided by 91 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 6501.1
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.

On to step 8:
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: 6501.1
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.

Advancing to step 9:
The number 91 fits into 900 9 times, leaving a remainder of 81.
The next digit of our result is 9. 
Result so far: 6501.109
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.

Advancing to step 10:
If we divide 810 by 91, we get 8 and a remainder of 82.
The next digit of our result is 8. 
Result so far: 6501.1098
Subtracting 728 from 810 leaves us 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 11:
91 can be fit into 820 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 6501.10989
Subtracting 819 from 820 leaves us 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.

Going ahead to step 12:
When dividing 10 by 91, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 6501.10989
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.

Let's proceed to step 13:
If we divide 100 by 91, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 6501.1098901
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.

Advancing to step 14:
91 goes into 90 0 times with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 6501.1098901
If we take 0 away from 90, we end up 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.

In conclusion, the division gives 6501.1098901 with a balance of 9e-08.
