903423 ÷ 8 
Let's see how many times 8 fits into 903423.

On to step 1:
The number 8 fits into 9 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 1 after subtracting 8 from 9.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 8

Step 2:
The number 8 fits into 10 1 times, leaving a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 8 from 10 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 8

Let's proceed to step 3:
The number 8 fits into 23 2 times, leaving a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 112.0
The remainder is 7 after subtracting 16 from 23.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 8

Advancing to step 4:
8 goes into 74 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 1129.0
If we take 72 away from 74, we end up with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 8

Let's proceed to step 5:
22 divided by 8 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 11292.0
Subtracting 16 from 22 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 8

Going ahead to step 6:
63 divided by 8 is 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 112927.0
If we take 56 away from 63, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
8 can be fit into 70 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 112927.8
If we subtract 64 from 70, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
8 goes into 60 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 112927.87
Subtracting 56 from 60 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 112927.875
Subtract 40 from 40 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.

Going ahead to step 10:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 112927.875
If we subtract 0 from 0, 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 11:
8 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 112927.875
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.

The final result is 112927.875 with a remainder of 0.0.
