We're dividing 162615 by 90 
We want to divide 162615 by 90.

Going ahead to step 1:
If we divide 1 by 90, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 90

Advancing to step 2:
90 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 90

On to step 3:
90 goes into 162 1 times with a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 90 from 162 to get 72.
Fetch the next digit (6) from the dividend, attach it to 72 and continue: 726 / 90

On to step 4:
90 goes into 726 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 6 after subtracting 720 from 726.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 90

Moving on to step 5:
90 goes into 61 0 times with a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 180.0
Subtract 0 from 61 to get 61.
Take the next digit (5) from the dividend and append it to 61, then repeat: 615 / 90

On to step 6:
The number 90 fits into 615 6 times, leaving a remainder of 75.
Use 6 as the next digit of our solution. 
Result so far: 1806.0
If we subtract 540 from 615, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 7:
90 can be fit into 750 8 times, resulting in a remainder of 30.
The next digit of our result is 8. 
Result so far: 1806.8
Deduct 720 from 750 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
The number 90 fits into 300 3 times, leaving a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 1806.83
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
90 goes into 300 3 times with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 1806.833
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 1806.833 and a remainder of 0.003.
