Let's divide 543426 by 8
Our goal is to divide 543426 by 8.

Advancing to step 1:
5 divided by 8 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 8

On to step 2:
When dividing 54 by 8, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 48 from 54 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 8

Going ahead to step 3:
If we divide 63 by 8, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 67.0
Deduct 56 from 63 and we're left with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 8

Step 4:
When dividing 74 by 8, we get 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 679.0
The remainder is 2 after subtracting 72 from 74.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 8

Going ahead to step 5:
If we divide 22 by 8, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 6792.0
Subtracting 16 from 22 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 8

Advancing to step 6:
8 can be fit into 66 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 67928.0
Subtract 64 from 66 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
If we divide 20 by 8, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 67928.2
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.

On to step 8:
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: 67928.25
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.

Step 9:
0 divided by 8 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 67928.25
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.

On to step 10:
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: 67928.25
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.

The final outcome is 67928.25, with a leftover of 0.0.
