We look at the division of 221785 by 12 
We want to figure out the number of times 221785 can be divided by 12.

Step 1:
When dividing 2 by 12, we get 0 with 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.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 12

Let's proceed to step 2:
22 divided by 12 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 12 from 22, we get 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 12

On to step 3:
101 divided by 12 is 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 18.0
Subtract 96 from 101 to get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 12

Advancing to step 4:
12 can be fit into 57 4 times, resulting in a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 184.0
If we take 48 away from 57, we end up with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 12

Moving on to step 5:
12 goes into 98 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 1848.0
If we subtract 96 from 98, we get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 12

Advancing to step 6:
When dividing 25 by 12, we get 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 18482.0
Subtracting 24 from 25 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
12 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 18482.0
If we take 0 away from 10, 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.

Moving on to step 8:
12 goes into 100 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 18482.08
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 18482.083
Deduct 36 from 40 and we're left 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.

Going ahead to step 10:
12 goes into 40 3 times with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 18482.0833
If we take 36 away from 40, we end up 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.

The quotient of the division is 18482.0833, and the remainder is 4e-05.
