We divide 220406 by 12
Our goal is to divide 220406 by 12.

Moving on to step 1:
The number 12 fits into 2 0 times, leaving 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.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 12

Step 2:
When dividing 22 by 12, we get 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 12 from 22 leaves us with 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 12

Let's proceed to step 3:
12 goes into 100 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 96 from 100 and we're left with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 12

On to step 4:
12 can be fit into 44 3 times, resulting in a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 183.0
If we take 36 away from 44, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 12

Going ahead to step 5:
If we divide 80 by 12, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 1836.0
The remainder is 8 after subtracting 72 from 80.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 12

Advancing to step 6:
If we divide 86 by 12, we get 7 and a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 18367.0
Subtracting 84 from 86 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
12 goes into 20 1 times with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 18367.1
If we take 12 away from 20, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
If we divide 80 by 12, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 18367.16
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
80 divided by 12 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 18367.166
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 18367.166, with a leftover of 0.0008.
