We look at the division of 990642 by 99 
We're looking to find how many times 99 goes into 990642.

Moving on to step 1:
99 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 99

Let's proceed to step 2:
99 goes into 99 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 99 from 99 leaves us with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 99

Advancing to step 3:
0 divided by 99 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 0 after subtracting 0 from 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 99

Step 4:
6 divided by 99 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 100.0
If we take 0 away from 6, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 99

Moving on to step 5:
99 can be fit into 64 0 times, resulting in a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 1000.0
The remainder is 64 after subtracting 0 from 64.
Fetch the next digit (2) from the dividend, attach it to 64 and continue: 642 / 99

Let's proceed to step 6:
99 goes into 642 6 times with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 10006.0
Subtract 594 from 642 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 7:
99 goes into 480 4 times with a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 10006.4
If we take 396 away from 480, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 8:
The number 99 fits into 840 8 times, leaving a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 10006.48
If we take 792 away from 840, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
480 divided by 99 is 4 with a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 10006.484
Subtracting 396 from 480 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 10:
If we divide 840 by 99, we get 8 and a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 10006.4848
If we subtract 792 from 840, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
If we divide 480 by 99, we get 4 and a remainder of 84.
Use 4 as the next digit of our solution. 
Result so far: 10006.48484
Subtracting 396 from 480 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 12:
If we divide 840 by 99, we get 8 and a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 10006.484848
If we subtract 792 from 840, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 13:
99 goes into 480 4 times with a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 10006.4848484
Subtract 396 from 480 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 14:
If we divide 840 by 99, we get 8 and a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 10006.48484848
The remainder is 48 after subtracting 792 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 10006.48484848, with a leftover of 4.8e-08.
