Let's divide 286278 by 68
We want to figure out the number of times 286278 can be divided by 68.

On to step 1:
When dividing 2 by 68, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 68

On to step 2:
68 can be fit into 28 0 times, resulting in a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 68

Step 3:
68 goes into 286 4 times with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 272 from 286 and we're left with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 68

Going ahead to step 4:
If we divide 142 by 68, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Deduct 136 from 142 and we're left with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 68

Step 5:
67 divided by 68 is 0 with a remainder of 67.
The next digit of our result is 0. 
Result so far: 420.0
If we take 0 away from 67, we end up with 67.
Grab the next digit (8) from the dividend, add it to 67, then carry on: 678 / 68

Let's proceed to step 6:
68 can be fit into 678 9 times, resulting in a remainder of 66.
The next digit of our result is 9. 
Result so far: 4209.0
Subtract 612 from 678 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 7:
68 goes into 660 9 times with a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 4209.9
Subtracting 612 from 660 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 8:
When dividing 480 by 68, we get 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 4209.97
Subtract 476 from 480 to 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.

Advancing to step 9:
The number 68 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 4209.97
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
If we divide 400 by 68, we get 5 and a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 4209.9705
Subtract 340 from 400 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
68 can be fit into 600 8 times, resulting in a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 4209.97058
If we take 544 away from 600, we end up 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 12:
If we divide 560 by 68, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 4209.970588
Subtracting 544 from 560 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 4209.970588, with a leftover of 1.6e-06.
