We're dividing 216420 by 22 
We want to divide 216420 by 22.

Step 1:
2 divided by 22 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 22

On to step 2:
21 divided by 22 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 22

Going ahead to step 3:
22 can be fit into 216 9 times, resulting in a remainder of 18.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 198 from 216 and we're left with 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 22

Going ahead to step 4:
When dividing 184 by 22, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 98.0
If we subtract 176 from 184, we get 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 22

Going ahead to step 5:
22 goes into 82 3 times with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 983.0
Subtract 66 from 82 to get 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 22

Moving on to step 6:
22 goes into 160 7 times with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 9837.0
If we take 154 away from 160, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
22 can be fit into 60 2 times, resulting in a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 9837.2
The remainder is 16 after subtracting 44 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
The number 22 fits into 160 7 times, leaving a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 9837.27
The remainder is 6 after subtracting 154 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
The number 22 fits into 60 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 9837.272
Deduct 44 from 60 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
If we divide 160 by 22, we get 7 and a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 9837.2727
If we take 154 away from 160, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
22 goes into 60 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 9837.27272
If we take 44 away from 60, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
When dividing 160 by 22, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 9837.272727
The remainder is 6 after subtracting 154 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
If we divide 60 by 22, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 9837.2727272
Subtract 44 from 60 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
22 goes into 160 7 times with a remainder of 6.
The next digit of our result is 7. 
Result so far: 9837.27272727
Deduct 154 from 160 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 9837.27272727 with a remaining 6e-09.
