We look at the division of 68400515 by 468 
We want to divide 68400515 by 468.

Let's proceed to step 1:
When dividing 6 by 468, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 468

Moving on to step 2:
468 goes into 68 0 times with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Grab the next digit (4) from the dividend, add it to 68, then carry on: 684 / 468

Advancing to step 3:
The number 468 fits into 684 1 times, leaving a remainder of 216.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 216 after subtracting 468 from 684.
Include the next digit (0) from the dividend after 216, then repeat: 2160 / 468

Step 4:
2160 divided by 468 is 4 with a remainder of 288.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtract 1872 from 2160 to get 288.
Bring next digit (0) of the dividend behind the 288 and repeat the process: 2880 / 468

Moving on to step 5:
If we divide 2880 by 468, we get 6 and a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 146.0
If we take 2808 away from 2880, we end up with 72.
Bring next digit (5) of the dividend behind the 72 and repeat the process: 725 / 468

Moving on to step 6:
468 can be fit into 725 1 times, resulting in a remainder of 257.
Put 1 as the next digit of the answer. 
Result so far: 1461.0
If we subtract 468 from 725, we get 257.
Include the next digit (1) from the dividend after 257, then repeat: 2571 / 468

On to step 7:
If we divide 2571 by 468, we get 5 and a remainder of 231.
Put 5 as the next digit of the answer. 
Result so far: 14615.0
Deduct 2340 from 2571 and we're left with 231.
Grab the next digit (5) from the dividend, add it to 231, then carry on: 2315 / 468

Going ahead to step 8:
If we divide 2315 by 468, we get 4 and a remainder of 443.
The next digit of our result is 4. 
Result so far: 146154.0
Subtracting 1872 from 2315 leaves us with 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Going ahead to step 9:
468 goes into 4430 9 times with a remainder of 218.
The next digit of our result is 9. 
Result so far: 146154.9
Deduct 4212 from 4430 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 10:
468 can be fit into 2180 4 times, resulting in a remainder of 308.
Record the quotient 4 as the next digit in the result. 
Result so far: 146154.94
Deduct 1872 from 2180 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 11:
468 goes into 3080 6 times with a remainder of 272.
Record the quotient 6 as the next digit in the result. 
Result so far: 146154.946
The remainder is 272 after subtracting 2808 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 12:
When dividing 2720 by 468, we get 5 with a remainder of 380.
Record the quotient 5 as the next digit in the result. 
Result so far: 146154.9465
The remainder is 380 after subtracting 2340 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 13:
3800 divided by 468 is 8 with a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 146154.94658
Subtracting 3744 from 3800 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 14:
If we divide 560 by 468, we get 1 and a remainder of 92.
Put 1 as the next digit of the answer. 
Result so far: 146154.946581
Subtract 468 from 560 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 15:
The number 468 fits into 920 1 times, leaving a remainder of 452.
Put 1 as the next digit of the answer. 
Result so far: 146154.9465811
Subtracting 468 from 920 leaves us with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

The final outcome is 146154.9465811, with a leftover of 4.52e-06.
