20215 ÷ 68 
We're looking to find how many times 68 goes into 20215.

Going ahead to step 1:
2 divided by 68 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 68

Let's proceed to step 2:
The number 68 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Append the next digit (2) from the dividend to 20 and continue with: 202 / 68

Moving on to step 3:
68 can be fit into 202 2 times, resulting in a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 136 from 202 leaves us with 66.
Include the next digit (1) from the dividend after 66, then repeat: 661 / 68

Moving on to step 4:
661 divided by 68 is 9 with a remainder of 49.
The next digit of our result is 9. 
Result so far: 29.0
Subtract 612 from 661 to get 49.
Grab the next digit (5) from the dividend, add it to 49, then carry on: 495 / 68

Going ahead to step 5:
The number 68 fits into 495 7 times, leaving a remainder of 19.
The next digit of our result is 7. 
Result so far: 297.0
Deduct 476 from 495 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 6:
When dividing 190 by 68, we get 2 with a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 297.2
If we take 136 away from 190, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 7:
68 goes into 540 7 times with a remainder of 64.
The number 7 becomes the next digit in our result. 
Result so far: 297.27
Subtracting 476 from 540 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 8:
When dividing 640 by 68, we get 9 with a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 297.279
Subtract 612 from 640 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
When dividing 280 by 68, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 297.2794
Subtract 272 from 280 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
The number 68 fits into 80 1 times, leaving a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 297.27941
If we take 68 away from 80, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
When dividing 120 by 68, we get 1 with a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 297.279411
Deduct 68 from 120 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 297.279411, with a leftover of 5.2e-06.
