We divide 243213 by 8
We want to figure out the number of times 243213 can be divided by 8.

Going ahead to step 1:
8 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 8

On to step 2:
8 goes into 24 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 24 from 24 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 8

Advancing to step 3:
The number 8 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtract 0 from 3 to get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 8

Let's proceed to step 4:
If we divide 32 by 8, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 304.0
Deduct 32 from 32 and we're left with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 8

Moving on to step 5:
1 divided by 8 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 3040.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 8

Step 6:
When dividing 13 by 8, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 30401.0
Subtract 8 from 13 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
50 divided by 8 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 30401.6
Deduct 48 from 50 and we're left with 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:
20 divided by 8 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 30401.62
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.

Step 9:
The number 8 fits into 40 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 30401.625
Subtract 40 from 40 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.

Let's proceed to step 10:
0 divided by 8 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30401.625
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.

Moving on to step 11:
8 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 30401.625
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.

Our division results in 30401.625 with a remaining 0.0.
