220519 ÷ 12 
We want to figure out the number of times 220519 can be divided by 12.

Going ahead to step 1:
If we divide 2 by 12, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 12

Let's proceed to step 2:
When dividing 22 by 12, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 12 from 22, we get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 12

Moving on to step 3:
When dividing 100 by 12, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 18.0
The remainder is 4 after subtracting 96 from 100.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 12

Step 4:
12 can be fit into 45 3 times, resulting in a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 183.0
If we take 36 away from 45, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 12

On to step 5:
12 goes into 91 7 times with a remainder of 7.
The next digit of our result is 7. 
Result so far: 1837.0
If we subtract 84 from 91, we get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 12

On to step 6:
12 goes into 79 6 times with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 18376.0
Deduct 72 from 79 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
If we divide 70 by 12, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 18376.5
If we take 60 away from 70, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 18376.58
Subtract 96 from 100 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
40 divided by 12 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 18376.583
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 18376.5833
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 18376.5833 with a balance of 4e-05.
