We're dividing 217790 by 2 
Our goal is to divide 217790 by 2.

On to step 1:
If we divide 2 by 2, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 2 from 2, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 2

Advancing to step 2:
If we divide 1 by 2, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 2

Going ahead to step 3:
2 goes into 17 8 times with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 108.0
Subtract 16 from 17 to get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 2

Advancing to step 4:
When dividing 17 by 2, we get 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 1088.0
The remainder is 1 after subtracting 16 from 17.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 2

Step 5:
The number 2 fits into 19 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 10889.0
Subtracting 18 from 19 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

Going ahead to step 6:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 108895.0
Subtract 10 from 10 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 108895.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 108895.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 108895.0 with a balance of 0.0.
