We divide 645224 by 8
We want to divide 645224 by 8.

Step 1:
8 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 8

Let's proceed to step 2:
If we divide 64 by 8, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 0 after subtracting 64 from 64.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 8

Going ahead to step 3:
When dividing 5 by 8, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
If we subtract 0 from 5, we get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 8

Let's proceed to step 4:
52 divided by 8 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 806.0
Deduct 48 from 52 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 8

Let's proceed to step 5:
8 can be fit into 42 5 times, resulting in a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 8065.0
Subtract 40 from 42 to get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 8

Step 6:
24 divided by 8 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 80653.0
Deduct 24 from 24 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.

On to step 7:
0 divided by 8 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 80653.0
Subtracting 0 from 0 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: 80653.0
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.

Our division results in 80653.0 with a remaining 0.0.
