We look at the division of 990661 by 48 
We want to divide 990661 by 48.

Going ahead to step 1:
The number 48 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 48

Step 2:
If we divide 99 by 48, we get 2 and a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 96 from 99 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 48

On to step 3:
48 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 30 to get 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 48

On to step 4:
The number 48 fits into 306 6 times, leaving a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 206.0
If we subtract 288 from 306, we get 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 48

Let's proceed to step 5:
When dividing 186 by 48, we get 3 with a remainder of 42.
The next digit of our result is 3. 
Result so far: 2063.0
If we subtract 144 from 186, we get 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 48

Advancing to step 6:
The number 48 fits into 421 8 times, leaving a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 20638.0
If we take 384 away from 421, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
48 goes into 370 7 times with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 20638.7
Deduct 336 from 370 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
The number 48 fits into 340 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 20638.77
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 20638.77 with a remaining 0.004.
