We're dividing 543402 by 8 
We want to divide 543402 by 8.

Going ahead to step 1:
The number 8 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 8

Advancing to step 2:
The number 8 fits into 54 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 48 away from 54, we end up with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 8

Advancing to step 3:
If we divide 63 by 8, we get 7 and a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
Deduct 56 from 63 and we're left with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 8

Going ahead to step 4:
If we divide 74 by 8, we get 9 and a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 679.0
If we subtract 72 from 74, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 8

Let's proceed to step 5:
8 goes into 20 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 6792.0
Deduct 16 from 20 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 8

Moving on to step 6:
If we divide 42 by 8, we get 5 and a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 67925.0
Subtracting 40 from 42 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.

Advancing to step 7:
When dividing 20 by 8, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 67925.2
If we subtract 16 from 20, we 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 8:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 67925.25
Deduct 40 from 40 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.

Going ahead to step 9:
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: 67925.25
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 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 67925.25
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.

The quotient of the division is 67925.25, and the remainder is 0.0.
