371339 ÷ 12 
We're looking to find how many times 12 goes into 371339.

Moving on to step 1:
If we divide 3 by 12, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
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

Step 2:
The number 12 fits into 37 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 36 from 37 to get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 12

Let's proceed to step 3:
When dividing 11 by 12, we get 0 with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtracting 0 from 11 leaves us with 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 12

On to step 4:
The number 12 fits into 113 9 times, leaving a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 309.0
Subtract 108 from 113 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 12

Advancing to step 5:
If we divide 53 by 12, we get 4 and a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 3094.0
Deduct 48 from 53 and we're left with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 12

Step 6:
The number 12 fits into 59 4 times, leaving a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 30944.0
Deduct 48 from 59 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
If we divide 110 by 12, we get 9 and a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 30944.9
Subtracting 108 from 110 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.

Advancing to step 8:
When dividing 20 by 12, we get 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 30944.91
Subtracting 12 from 20 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.

Step 9:
When dividing 80 by 12, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 30944.916
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.

Let's proceed to step 10:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 30944.9166
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.

Our division results in 30944.9166 with a remaining 8e-05.
