We look at the division of 990381 by 6 
We want to figure out the number of times 990381 can be divided by 6.

On to step 1:
If we divide 9 by 6, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 3 after subtracting 6 from 9.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 6

Step 2:
6 goes into 39 6 times with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 36 from 39 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 6

Advancing to step 3:
30 divided by 6 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 165.0
The remainder is 0 after subtracting 30 from 30.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 6

Step 4:
6 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 1650.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 6

Advancing to step 5:
If we divide 38 by 6, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 16506.0
Subtract 36 from 38 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 6

Advancing to step 6:
21 divided by 6 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 165063.0
The remainder is 3 after subtracting 18 from 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
If we divide 30 by 6, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 165063.5
If we subtract 30 from 30, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
If we divide 0 by 6, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 165063.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 6, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 165063.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 165063.5 and a remainder of 0.0.
