We look at the division of 68315060 by 459 
We want to figure out the number of times 68315060 can be divided by 459.

Step 1:
459 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 459

Moving on to step 2:
When dividing 68 by 459, we get 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Include the next digit (3) from the dividend after 68, then repeat: 683 / 459

Going ahead to step 3:
683 divided by 459 is 1 with a remainder of 224.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 459 away from 683, we end up with 224.
Append the next digit (1) from the dividend to 224 and continue with: 2241 / 459

On to step 4:
When dividing 2241 by 459, we get 4 with a remainder of 405.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 1836 away from 2241, we end up with 405.
Append the next digit (5) from the dividend to 405 and continue with: 4055 / 459

Step 5:
459 goes into 4055 8 times with a remainder of 383.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
Subtracting 3672 from 4055 leaves us with 383.
Append the next digit (0) from the dividend to 383 and continue with: 3830 / 459

Going ahead to step 6:
459 can be fit into 3830 8 times, resulting in a remainder of 158.
The number 8 becomes the next digit in our result. 
Result so far: 1488.0
Subtracting 3672 from 3830 leaves us with 158.
Include the next digit (6) from the dividend after 158, then repeat: 1586 / 459

Let's proceed to step 7:
The number 459 fits into 1586 3 times, leaving a remainder of 209.
Put 3 as the next digit of the answer. 
Result so far: 14883.0
If we take 1377 away from 1586, we end up with 209.
Fetch the next digit (0) from the dividend, attach it to 209 and continue: 2090 / 459

Step 8:
2090 divided by 459 is 4 with a remainder of 254.
Write down 4 as next digit of the result. 
Result so far: 148834.0
If we subtract 1836 from 2090, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 9:
459 goes into 2540 5 times with a remainder of 245.
Record the quotient 5 as the next digit in the result. 
Result so far: 148834.5
If we take 2295 away from 2540, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 10:
2450 divided by 459 is 5 with a remainder of 155.
Write down 5 as next digit of the result. 
Result so far: 148834.55
Subtract 2295 from 2450 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Our division results in 148834.55 with a remaining 0.155.
