198273 divided by 12 
Let's see how many times 12 fits into 198273.

Step 1:
If we divide 1 by 12, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 12

Moving on to step 2:
If we divide 19 by 12, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 12 from 19, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 12

Advancing to step 3:
12 can be fit into 78 6 times, resulting in a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 6 after subtracting 72 from 78.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 12

On to step 4:
62 divided by 12 is 5 with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 165.0
If we take 60 away from 62, we end up with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 12

Going ahead to step 5:
12 goes into 27 2 times with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 1652.0
The remainder is 3 after subtracting 24 from 27.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 12

Going ahead to step 6:
12 goes into 33 2 times with a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 16522.0
If we take 24 away from 33, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
12 goes into 90 7 times with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 16522.7
Deduct 84 from 90 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.

Going ahead to step 8:
The number 12 fits into 60 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 16522.75
If we subtract 60 from 60, 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.

Let's proceed to step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16522.75
Subtracting 0 from 0 leaves us 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.

Advancing to step 10:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16522.75
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.

After the division, we end up with 16522.75 and a remainder of 0.0.
