374970 ÷ 12 
Let's see how many times 12 fits into 374970.

Moving on to step 1:
When dividing 3 by 12, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 12

On to step 2:
When dividing 37 by 12, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 36 from 37 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 12

Moving on to step 3:
12 can be fit into 14 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtract 12 from 14 to get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 12

Going ahead to step 4:
When dividing 29 by 12, we get 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 312.0
If we subtract 24 from 29, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 12

Advancing to step 5:
When dividing 57 by 12, we get 4 with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 3124.0
Subtracting 48 from 57 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 12

On to step 6:
12 can be fit into 90 7 times, resulting in a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 31247.0
Subtracting 84 from 90 leaves us 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 7:
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: 31247.5
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.

Moving on to step 8:
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: 31247.5
If we subtract 0 from 0, 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.

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: 31247.5
If we take 0 away from 0, 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.

The final outcome is 31247.5, with a leftover of 0.0.
