We're dividing 219978 by 18 
Let's see how many times 18 fits into 219978.

On to step 1:
2 divided by 18 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 18

Let's proceed to step 2:
18 goes into 21 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 18 from 21 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 18

On to step 3:
18 can be fit into 39 2 times, resulting in a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 36 from 39, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 18

Advancing to step 4:
If we divide 39 by 18, we get 2 and a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 122.0
Subtract 36 from 39 to get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 18

Let's proceed to step 5:
If we divide 37 by 18, we get 2 and a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 1222.0
Deduct 36 from 37 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 18

Going ahead to step 6:
When dividing 18 by 18, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 12221.0
If we subtract 18 from 18, 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.

Advancing to step 7:
The number 18 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12221.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
0 divided by 18 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12221.0
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.

Our division results in 12221.0 with a remaining 0.0.
