803742 ÷ 90 
We want to divide 803742 by 90.

Step 1:
8 divided by 90 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 90

On to step 2:
80 divided by 90 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Take the next digit (3) from the dividend and append it to 80, then repeat: 803 / 90

Let's proceed to step 3:
When dividing 803 by 90, we get 8 with a remainder of 83.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 720 away from 803, we end up with 83.
Take the next digit (7) from the dividend and append it to 83, then repeat: 837 / 90

Step 4:
837 divided by 90 is 9 with a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 89.0
The remainder is 27 after subtracting 810 from 837.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 90

Step 5:
90 goes into 274 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 893.0
The remainder is 4 after subtracting 270 from 274.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 90

Moving on to step 6:
42 divided by 90 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 8930.0
If we take 0 away from 42, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 7:
If we divide 420 by 90, we get 4 and a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 8930.4
Subtracting 360 from 420 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
If we divide 600 by 90, we get 6 and a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 8930.46
Deduct 540 from 600 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
The number 90 fits into 600 6 times, leaving a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 8930.466
If we subtract 540 from 600, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 8930.466, with a leftover of 0.006.
