543321 ÷ 8 
We want to divide 543321 by 8.

Going ahead to step 1:
8 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 8

Step 2:
8 can be fit into 54 6 times, resulting in a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 48 from 54, we get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 8

Going ahead to step 3:
63 divided by 8 is 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
The remainder is 7 after subtracting 56 from 63.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 8

On to step 4:
The number 8 fits into 73 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 679.0
If we take 72 away from 73, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 8

On to step 5:
12 divided by 8 is 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 6791.0
Deduct 8 from 12 and we're left with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 8

On to step 6:
41 divided by 8 is 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 67915.0
If we subtract 40 from 41, we get 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 goes into 10 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 67915.1
Subtracting 8 from 10 leaves us 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.

Moving on to step 8:
When dividing 20 by 8, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 67915.12
Subtract 16 from 20 to get 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:
8 can be fit into 40 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 67915.125
Subtracting 40 from 40 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.

Step 10:
0 divided by 8 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 67915.125
Deduct 0 from 0 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.

Advancing to step 11:
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: 67915.125
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.

The quotient of the division is 67915.125, and the remainder is 0.0.
