We look at the division of 907644 by 18 
We're looking to find how many times 18 goes into 907644.

Step 1:
The number 18 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 18

Going ahead to step 2:
90 divided by 18 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 90 from 90, we get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 18

Moving on to step 3:
The number 18 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 50.0
If we take 0 away from 7, we end up with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 18

Let's proceed to step 4:
18 goes into 76 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 504.0
If we take 72 away from 76, we end up with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 18

On to step 5:
If we divide 44 by 18, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 5042.0
If we subtract 36 from 44, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 18

Going ahead to step 6:
84 divided by 18 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 50424.0
If we subtract 72 from 84, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
The number 18 fits into 120 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 50424.6
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
18 goes into 120 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 50424.66
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 50424.66, with a leftover of 0.012.
