We divide 1343 by 90
We want to divide 1343 by 90.

Step 1:
90 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 90

Advancing to step 2:
If we divide 13 by 90, we get 0 and a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 90

On to step 3:
90 can be fit into 134 1 times, resulting in a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 90 from 134 leaves us with 44.
Append the next digit (3) from the dividend to 44 and continue with: 443 / 90

Advancing to step 4:
443 divided by 90 is 4 with a remainder of 83.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 360 from 443 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 5:
When dividing 830 by 90, we get 9 with a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 14.9
If we subtract 810 from 830, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 6:
90 can be fit into 200 2 times, resulting in a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 14.92
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
When dividing 200 by 90, we get 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 14.922
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 14.922, with a leftover of 0.002.
