We divide 217802 by 78
We're looking to find how many times 78 goes into 217802.

Step 1:
The number 78 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 78

Advancing to step 2:
The number 78 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 78

Let's proceed to step 3:
217 divided by 78 is 2 with a remainder of 61.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 156 from 217, we get 61.
Take the next digit (8) from the dividend and append it to 61, then repeat: 618 / 78

Going ahead to step 4:
When dividing 618 by 78, we get 7 with a remainder of 72.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Deduct 546 from 618 and we're left with 72.
Append the next digit (0) from the dividend to 72 and continue with: 720 / 78

Advancing to step 5:
When dividing 720 by 78, we get 9 with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 279.0
Deduct 702 from 720 and we're left with 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 78

Advancing to step 6:
The number 78 fits into 182 2 times, leaving a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 2792.0
The remainder is 26 after subtracting 156 from 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
78 goes into 260 3 times with a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 2792.3
The remainder is 26 after subtracting 234 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
If we divide 260 by 78, we get 3 and a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 2792.33
The remainder is 26 after subtracting 234 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 2792.33 with a remainder of 0.026.
