451708 ÷ 8 
We want to figure out the number of times 451708 can be divided by 8.

Let's proceed to step 1:
When dividing 4 by 8, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 8

Advancing to step 2:
8 goes into 45 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 40 from 45, we get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 8

Moving on to step 3:
When dividing 51 by 8, we get 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 56.0
Deduct 48 from 51 and we're left with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 8

Let's proceed to step 4:
If we divide 37 by 8, we get 4 and a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 564.0
If we take 32 away from 37, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 8

Going ahead to step 5:
50 divided by 8 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 5646.0
If we subtract 48 from 50, we get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 8

Step 6:
28 divided by 8 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 56463.0
Subtract 24 from 28 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
8 goes into 40 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 56463.5
Subtracting 40 from 40 leaves us 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 8:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 56463.5
If we take 0 away from 0, we end up 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.

Step 9:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 56463.5
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.

The final result is 56463.5 with a remainder of 0.0.
