903691 divided by 18 
Let's see how many times 18 fits into 903691.

On to step 1:
The number 18 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.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 18

Advancing to step 2:
18 can be fit into 90 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 90 from 90 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 18

On to step 3:
3 divided by 18 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 50.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 18

Advancing to step 4:
18 goes into 36 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 502.0
Subtracting 36 from 36 leaves us with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 18

Step 5:
The number 18 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 5020.0
If we subtract 0 from 9, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 18

Advancing to step 6:
18 goes into 91 5 times with a remainder of 1.
The next digit of our result is 5. 
Result so far: 50205.0
Subtract 90 from 91 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
18 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 50205.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
100 divided by 18 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 50205.05
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
If we divide 100 by 18, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 50205.055
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 50205.055, and the remainder is 0.001.
