Let's divide 450721 by 8
We want to figure out the number of times 450721 can be divided by 8.

Advancing to step 1:
If we divide 4 by 8, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 8

Advancing to step 2:
The number 8 fits into 45 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 40 from 45, we get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 8

Moving on to step 3:
If we divide 50 by 8, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
If we subtract 48 from 50, we get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 8

Let's proceed to step 4:
If we divide 27 by 8, we get 3 and a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 563.0
If we subtract 24 from 27, we get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 8

Let's proceed to step 5:
8 can be fit into 32 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 5634.0
The remainder is 0 after subtracting 32 from 32.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 8

Let's proceed to step 6:
8 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 56340.0
The remainder is 1 after subtracting 0 from 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
10 divided by 8 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 56340.1
Subtract 8 from 10 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
The number 8 fits into 20 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 56340.12
Subtracting 16 from 20 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.

Let's proceed to step 9:
8 goes into 40 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 56340.125
The remainder is 0 after subtracting 40 from 40.
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 10:
If we divide 0 by 8, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 56340.125
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.

Step 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 56340.125
Subtract 0 from 0 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.

The final result is 56340.125 with a remainder of 0.0.
