We look at the division of 174870 by 12 
Let's see how many times 12 fits into 174870.

On to step 1:
12 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 12

Moving on to step 2:
12 can be fit into 17 1 times, resulting in a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 12 from 17, we get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 12

Let's proceed to step 3:
If we divide 54 by 12, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 48 from 54 and we're left with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 12

Moving on to step 4:
12 goes into 68 5 times with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 145.0
If we subtract 60 from 68, we get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 12

Advancing to step 5:
12 can be fit into 87 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 1457.0
If we subtract 84 from 87, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 12

Moving on to step 6:
The number 12 fits into 30 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 14572.0
Subtract 24 from 30 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 14572.5
If we take 60 away from 60, we end up 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 8:
If we divide 0 by 12, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14572.5
Deduct 0 from 0 and we're left 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.

On to step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 14572.5
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.

The final outcome is 14572.5, with a leftover of 0.0.
