520243 ÷ 8 
We want to figure out the number of times 520243 can be divided by 8.

Going ahead to step 1:
The number 8 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 8

Let's proceed to step 2:
If we divide 52 by 8, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 48 from 52 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 8

Step 3:
The number 8 fits into 40 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
Subtract 40 from 40 to get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 8

Advancing to step 4:
2 divided by 8 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 650.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 8

On to step 5:
8 goes into 24 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 6503.0
Deduct 24 from 24 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 8

Step 6:
8 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 65030.0
If we subtract 0 from 3, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
When dividing 30 by 8, we get 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 65030.3
The remainder is 6 after subtracting 24 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
8 goes into 60 7 times with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 65030.37
Deduct 56 from 60 and we're left 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.

Step 9:
If we divide 40 by 8, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 65030.375
If we take 40 away from 40, 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.

Moving on to step 10:
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: 65030.375
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.

Step 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 65030.375
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.

The quotient of the division is 65030.375, and the remainder is 0.0.
