We divide 1201158 by 90
We want to divide 1201158 by 90.

Step 1:
1 divided by 90 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 90

On to step 2:
When dividing 12 by 90, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 90

Let's proceed to step 3:
90 can be fit into 120 1 times, resulting in a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 90 away from 120, we end up with 30.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 90

Let's proceed to step 4:
When dividing 301 by 90, we get 3 with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 31 after subtracting 270 from 301.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 90

Advancing to step 5:
If we divide 311 by 90, we get 3 and a remainder of 41.
The next digit of our result is 3. 
Result so far: 133.0
If we subtract 270 from 311, we get 41.
Bring next digit (5) of the dividend behind the 41 and repeat the process: 415 / 90

Moving on to step 6:
When dividing 415 by 90, we get 4 with a remainder of 55.
Use 4 as the next digit of our solution. 
Result so far: 1334.0
If we subtract 360 from 415, we get 55.
Fetch the next digit (8) from the dividend, attach it to 55 and continue: 558 / 90

Step 7:
The number 90 fits into 558 6 times, leaving a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 13346.0
The remainder is 18 after subtracting 540 from 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
90 goes into 180 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 13346.2
Deduct 180 from 180 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
The number 90 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13346.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
90 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 13346.2
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 13346.2, and the remainder is 0.0.
