We look at the division of 17903 by 1 
Our goal is to divide 17903 by 1.

Going ahead to step 1:
When dividing 1 by 1, we get 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 0 after subtracting 1 from 1.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

On to step 2:
1 goes into 7 7 times with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtracting 7 from 7 leaves us with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Step 3:
9 divided by 1 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 179.0
Subtract 9 from 9 to get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

On to step 4:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1790.0
If we subtract 0 from 0, we get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

On to step 5:
1 goes into 3 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 17903.0
If we subtract 3 from 3, 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.

Moving on to step 6:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17903.0
Deduct 0 from 0 and we're left 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.

Advancing to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17903.0
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 17903.0 and a remainder of 0.0.
