248970 divided by 12 
We want to divide 248970 by 12.

On to step 1:
12 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 12

Advancing to step 2:
When dividing 24 by 12, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 24 away from 24, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 12

On to step 3:
If we divide 8 by 12, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 12

Step 4:
If we divide 89 by 12, we get 7 and a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 207.0
Deduct 84 from 89 and we're left with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 12

Moving on to step 5:
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: 2074.0
Deduct 48 from 57 and we're left with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 12

Step 6:
90 divided by 12 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 20747.0
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.

Let's proceed to step 7:
60 divided by 12 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 20747.5
Subtract 60 from 60 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.

Advancing to step 8:
0 divided by 12 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 20747.5
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.

On to step 9:
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: 20747.5
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.

After the division, we end up with 20747.5 and a remainder of 0.0.
