We divide 545815 by 8
We want to divide 545815 by 8.

Step 1:
When dividing 5 by 8, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 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.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 48 from 54 to get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 8

Let's proceed to step 3:
The number 8 fits into 65 8 times, leaving a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
If we subtract 64 from 65, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 8

Advancing to step 4:
The number 8 fits into 18 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 682.0
Subtract 16 from 18 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 8

Going ahead to step 5:
The number 8 fits into 21 2 times, leaving a remainder of 5.
The next digit of our result is 2. 
Result so far: 6822.0
Subtract 16 from 21 to get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 8

Advancing to step 6:
55 divided by 8 is 6 with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 68226.0
Deduct 48 from 55 and we're left 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.

Moving on to step 7:
When dividing 70 by 8, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 68226.8
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.

Step 8:
8 can be fit into 60 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 68226.87
If we subtract 56 from 60, 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.

Let's proceed to step 9:
When dividing 40 by 8, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 68226.875
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.

Advancing to step 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 68226.875
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.

On to step 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 68226.875
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.

The final outcome is 68226.875, with a leftover of 0.0.
