We look at the division of 612543 by 8 
We're looking to find how many times 8 goes into 612543.

Step 1:
8 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 8

Let's proceed to step 2:
When dividing 61 by 8, we get 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 56 from 61 to get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 8

Moving on to step 3:
If we divide 52 by 8, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 76.0
If we take 48 away from 52, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 8

Moving on to step 4:
8 goes into 45 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 765.0
Subtracting 40 from 45 leaves us with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 8

Moving on to step 5:
8 can be fit into 54 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 7656.0
Subtracting 48 from 54 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 8

Step 6:
The number 8 fits into 63 7 times, leaving a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 76567.0
If we take 56 away from 63, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
When dividing 70 by 8, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 76567.8
The remainder is 6 after subtracting 64 from 70.
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:
If we divide 60 by 8, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 76567.87
If we take 56 away from 60, we end up 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.

Advancing to step 9:
If we divide 40 by 8, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 76567.875
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.

Step 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 76567.875
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.

Advancing to step 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 76567.875
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.

After the division, we end up with 76567.875 and a remainder of 0.0.
