We look at the division of 400103 by 18 
We want to figure out the number of times 400103 can be divided by 18.

Going ahead to step 1:
If we divide 4 by 18, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 18

On to step 2:
18 can be fit into 40 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 36 away from 40, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 18

Moving on to step 3:
40 divided by 18 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtract 36 from 40 to get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 18

Moving on to step 4:
If we divide 41 by 18, we get 2 and a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 222.0
The remainder is 5 after subtracting 36 from 41.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 18

Let's proceed to step 5:
When dividing 50 by 18, we get 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 2222.0
If we subtract 36 from 50, we get 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 18

Advancing to step 6:
143 divided by 18 is 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 22227.0
Subtracting 126 from 143 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
170 divided by 18 is 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 22227.9
If we subtract 162 from 170, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
When dividing 80 by 18, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 22227.94
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
18 can be fit into 80 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 22227.944
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 22227.944, and the remainder is 0.0008.
