734640 ÷ 8 
We're looking to find how many times 8 goes into 734640.

Advancing to step 1:
8 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 8

Advancing to step 2:
When dividing 73 by 8, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 72 from 73 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 8

Advancing to step 3:
8 can be fit into 14 1 times, resulting in a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 91.0
If we subtract 8 from 14, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 8

On to step 4:
When dividing 66 by 8, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 918.0
Subtract 64 from 66 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 8

Let's proceed to step 5:
8 goes into 24 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 9183.0
If we subtract 24 from 24, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 8

Step 6:
8 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 91830.0
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.

Going ahead to step 7:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 91830.0
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 8:
0 divided by 8 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 91830.0
The remainder is 0 after subtracting 0 from 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 outcome is 91830.0, with a leftover of 0.0.
