We divide 217101 by 18
Let's see how many times 18 fits into 217101.

Advancing to step 1:
The number 18 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 18

Step 2:
18 goes into 21 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 18 from 21, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 18

Let's proceed to step 3:
18 can be fit into 37 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 36 from 37, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 18

Going ahead to step 4:
18 goes into 11 0 times with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 120.0
Deduct 0 from 11 and we're left with 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 18

Let's proceed to step 5:
18 goes into 110 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 1206.0
If we take 108 away from 110, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 18

Let's proceed to step 6:
When dividing 21 by 18, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 12061.0
If we subtract 18 from 21, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
When dividing 30 by 18, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 12061.1
Subtract 18 from 30 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
120 divided by 18 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 12061.16
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
If we divide 120 by 18, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 12061.166
Subtracting 108 from 120 leaves us 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.

The final result is 12061.166 with a remainder of 0.0012.
