We look at the division of 37999 by 12 
Our goal is to divide 37999 by 12.

Going ahead 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
Subtract 0 from 3 to get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 12

Moving on to step 2:
When dividing 37 by 12, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 36 from 37 leaves us with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 12

Advancing to step 3:
If we divide 19 by 12, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we subtract 12 from 19, we get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 12

Going ahead to step 4:
When dividing 79 by 12, we get 6 with a remainder of 7.
The next digit of our result is 6. 
Result so far: 316.0
The remainder is 7 after subtracting 72 from 79.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 12

Let's proceed to step 5:
When dividing 79 by 12, we get 6 with a remainder of 7.
The next digit of our result is 6. 
Result so far: 3166.0
Subtract 72 from 79 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 6:
70 divided by 12 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 3166.5
If we take 60 away from 70, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
12 goes into 100 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 3166.58
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
If we divide 40 by 12, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 3166.583
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
12 goes into 40 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3166.5833
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 3166.5833, with a leftover of 4e-05.
