We divide 1942 by 90
Let's see how many times 90 fits into 1942.

On to step 1:
90 can be fit into 1 0 times, resulting in 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.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 90

Moving on to step 2:
When dividing 19 by 90, we get 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 90

Moving on to step 3:
90 can be fit into 194 2 times, resulting in a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 14 after subtracting 180 from 194.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 90

Step 4:
90 goes into 142 1 times with a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 52 after subtracting 90 from 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 5:
90 goes into 520 5 times with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 21.5
If we take 450 away from 520, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 6:
90 can be fit into 700 7 times, resulting in a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 21.57
If we take 630 away from 700, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
When dividing 700 by 90, we get 7 with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 21.577
If we subtract 630 from 700, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 21.577, and the remainder is 0.007.
