We look at the division of 12613 by 90 
We want to divide 12613 by 90.

On to step 1:
1 divided by 90 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 90

Going ahead to step 2:
The number 90 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 90

Let's proceed to step 3:
If we divide 126 by 90, we get 1 and a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 36 after subtracting 90 from 126.
Include the next digit (1) from the dividend after 36, then repeat: 361 / 90

Let's proceed to step 4:
The number 90 fits into 361 4 times, leaving a remainder of 1.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 360 from 361 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 90

Going ahead to step 5:
The number 90 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 140.0
If we subtract 0 from 13, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 6:
If we divide 130 by 90, we get 1 and a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 140.1
If we subtract 90 from 130, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 7:
When dividing 400 by 90, we get 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 140.14
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
90 can be fit into 400 4 times, resulting in a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 140.144
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 140.144 with a balance of 0.004.
