120358 divided by 90 
We want to divide 120358 by 90.

Let's proceed to step 1:
90 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 90

Let's proceed to step 2:
90 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 90

Step 3:
120 divided by 90 is 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 90 from 120 and we're left with 30.
Fetch the next digit (3) from the dividend, attach it to 30 and continue: 303 / 90

Advancing to step 4:
When dividing 303 by 90, we get 3 with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 270 from 303, we get 33.
Grab the next digit (5) from the dividend, add it to 33, then carry on: 335 / 90

Let's proceed to step 5:
When dividing 335 by 90, we get 3 with a remainder of 65.
Use 3 as the next digit of our solution. 
Result so far: 133.0
Deduct 270 from 335 and we're left with 65.
Fetch the next digit (8) from the dividend, attach it to 65 and continue: 658 / 90

Going ahead to step 6:
When dividing 658 by 90, we get 7 with a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 1337.0
Subtract 630 from 658 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 7:
90 can be fit into 280 3 times, resulting in a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 1337.3
If we take 270 away from 280, we end up 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.

Going ahead to step 8:
The number 90 fits into 100 1 times, leaving a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1337.31
If we take 90 away from 100, we end up 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 9:
If we divide 100 by 90, we get 1 and a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1337.311
Deduct 90 from 100 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.

The quotient of the division is 1337.311, and the remainder is 0.001.
