Let's divide 990642 by 54
Let's see how many times 54 fits into 990642.

Advancing to step 1:
54 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 54

Advancing to step 2:
If we divide 99 by 54, we get 1 and a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 54 from 99 leaves us with 45.
Fetch the next digit (0) from the dividend, attach it to 45 and continue: 450 / 54

On to step 3:
When dividing 450 by 54, we get 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we take 432 away from 450, we end up with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 54

Advancing to step 4:
54 goes into 186 3 times with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 183.0
The remainder is 24 after subtracting 162 from 186.
Append the next digit (4) from the dividend to 24 and continue with: 244 / 54

Let's proceed to step 5:
If we divide 244 by 54, we get 4 and a remainder of 28.
The next digit of our result is 4. 
Result so far: 1834.0
The remainder is 28 after subtracting 216 from 244.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 54

On to step 6:
282 divided by 54 is 5 with a remainder of 12.
Record the quotient 5 as the next digit in the result. 
Result so far: 18345.0
Subtracting 270 from 282 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
The number 54 fits into 120 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 18345.2
If we subtract 108 from 120, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
If we divide 120 by 54, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 18345.22
If we take 108 away from 120, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 18345.22 with a remaining 0.012.
