Let's divide 839382 by 45
Our goal is to divide 839382 by 45.

Moving on to step 1:
When dividing 8 by 45, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 45

On to step 2:
The number 45 fits into 83 1 times, leaving a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 45 from 83 leaves us with 38.
Include the next digit (9) from the dividend after 38, then repeat: 389 / 45

Going ahead to step 3:
45 can be fit into 389 8 times, resulting in a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we take 360 away from 389, we end up with 29.
Take the next digit (3) from the dividend and append it to 29, then repeat: 293 / 45

On to step 4:
If we divide 293 by 45, we get 6 and a remainder of 23.
The next digit of our result is 6. 
Result so far: 186.0
If we subtract 270 from 293, we get 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 45

On to step 5:
When dividing 238 by 45, we get 5 with a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 1865.0
The remainder is 13 after subtracting 225 from 238.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 45

Advancing to step 6:
If we divide 132 by 45, we get 2 and a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 18652.0
Subtract 90 from 132 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 7:
When dividing 420 by 45, we get 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 18652.9
Deduct 405 from 420 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
45 goes into 150 3 times with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 18652.93
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
45 goes into 150 3 times with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 18652.933
Subtracting 135 from 150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 18652.933 with a remainder of 0.0015.
