If we take 40 away from 46, we end up with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 8

Step 5:
8 can be fit into 68 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 5358.0
Subtract 64 from 68 to get 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 8

Subtract 40 from 46 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
If we divide 60 by 8, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 53585.7
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 8:
40 divided by 8 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 53585.75
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.

On to step 9:
8 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 53585.75
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 10:
0 divided by 8 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 53585.75
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.

In conclusion, the division gives 53585.75 with a balance of 0.0.
