Let's divide 175243 by 12
Our goal is to divide 175243 by 12.

Step 1:
When dividing 1 by 12, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 12

Moving on to step 2:
17 divided by 12 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 12 from 17, we get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 12

Let's proceed to step 3:
The number 12 fits into 55 4 times, leaving a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 48 from 55 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 12

Advancing to step 4:
If we divide 72 by 12, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 146.0
If we take 72 away from 72, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 12

On to step 5:
If we divide 4 by 12, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 1460.0
Subtract 0 from 4 to get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 12

Step 6:
12 can be fit into 43 3 times, resulting in a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 14603.0
If we subtract 36 from 43, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
The number 12 fits into 70 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 14603.5
Deduct 60 from 70 and we're left 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.

Going ahead to step 8:
100 divided by 12 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 14603.58
If we take 96 away from 100, 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.

Moving on to step 9:
When dividing 40 by 12, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 14603.583
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.

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: 14603.5833
Subtract 36 from 40 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.

After the division, we end up with 14603.5833 and a remainder of 4e-05.
