We look at the division of 377645 by 12 
Our goal is to divide 377645 by 12.

Let's proceed to step 1:
If we divide 3 by 12, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 12

Going ahead to step 2:
12 can be fit into 37 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 36 from 37 to get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 12

On to step 3:
The number 12 fits into 17 1 times, leaving a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtracting 12 from 17 leaves us with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 12

Advancing to step 4:
56 divided by 12 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 314.0
Subtract 48 from 56 to get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 12

Going ahead to step 5:
12 goes into 84 7 times with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 3147.0
If we take 84 away from 84, we end up with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 12

Let's proceed to step 6:
12 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 31470.0
If we subtract 0 from 5, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
If we divide 50 by 12, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 31470.4
Subtracting 48 from 50 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
If we divide 20 by 12, we get 1 and a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 31470.41
The remainder is 8 after subtracting 12 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 31470.416
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 31470.4166
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 31470.4166, with a leftover of 8e-05.
