Let's divide 136490 by 91
Our goal is to divide 136490 by 91.

Going ahead to step 1:
When dividing 1 by 91, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 91

Moving on to step 2:
13 divided by 91 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 91

Let's proceed to step 3:
If we divide 136 by 91, we get 1 and a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 91 from 136 and we're left with 45.
Take the next digit (4) from the dividend and append it to 45, then repeat: 454 / 91

Advancing to step 4:
91 can be fit into 454 4 times, resulting in a remainder of 90.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 364 from 454 leaves us with 90.
Append the next digit (9) from the dividend to 90 and continue with: 909 / 91

Moving on to step 5:
909 divided by 91 is 9 with a remainder of 90.
Put 9 as the next digit of the answer. 
Result so far: 149.0
The remainder is 90 after subtracting 819 from 909.
Include the next digit (0) from the dividend after 90, then repeat: 900 / 91

Advancing to step 6:
900 divided by 91 is 9 with a remainder of 81.
The number 9 becomes the next digit in our result. 
Result so far: 1499.0
If we take 819 away from 900, we end up 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.

Moving on to step 7:
91 can be fit into 810 8 times, resulting in a remainder of 82.
The next digit of our result is 8. 
Result so far: 1499.8
If we subtract 728 from 810, we 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.

On to step 8:
91 goes into 820 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 1499.89
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.

Let's proceed to step 9:
91 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1499.89
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.

Advancing to step 10:
100 divided by 91 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 1499.8901
If we subtract 91 from 100, we 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.

Step 11:
91 can be fit into 90 0 times, resulting in a remainder of 90.
The next digit of our result is 0. 
Result so far: 1499.8901
If we subtract 0 from 90, we 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.

Moving on 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: 1499.890109
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 13:
The number 91 fits into 810 8 times, leaving a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 1499.8901098
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.

Moving on to step 14:
91 can be fit into 820 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 1499.89010989
Deduct 819 from 820 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.

The final result is 1499.89010989 with a remainder of 1e-09.
