We look at the division of 645225 by 8 
We want to divide 645225 by 8.

Going ahead to step 1:
The number 8 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 8

Going ahead to step 2:
8 can be fit into 64 8 times, resulting in a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 64 from 64 leaves us with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 8

Moving on to step 3:
The number 8 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 8

Step 4:
8 can be fit into 52 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 806.0
The remainder is 4 after subtracting 48 from 52.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 8

Going ahead to step 5:
When dividing 42 by 8, we get 5 with a remainder of 2.
The next digit of our result is 5. 
Result so far: 8065.0
If we subtract 40 from 42, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 8

Going ahead to step 6:
The number 8 fits into 25 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 80653.0
Subtracting 24 from 25 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
8 can be fit into 10 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 80653.1
The remainder is 2 after subtracting 8 from 10.
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:
8 can be fit into 20 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 80653.12
If we take 16 away from 20, we end up 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.

On to step 9:
The number 8 fits into 40 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 80653.125
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.

Going ahead to step 10:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 80653.125
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.

Going ahead to step 11:
If we divide 0 by 8, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 80653.125
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 outcome is 80653.125, with a leftover of 0.0.
