We're dividing 37508930 by 12 
We want to divide 37508930 by 12.

Step 1:
12 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 12

Moving on to step 2:
If we divide 37 by 12, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 3.0
If we take 36 away from 37, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 12

Moving on to step 3:
When dividing 15 by 12, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we subtract 12 from 15, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 12

On to step 4:
If we divide 30 by 12, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 312.0
Deduct 24 from 30 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 12

Going ahead to step 5:
68 divided by 12 is 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 3125.0
Subtract 60 from 68 to get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 12

On to step 6:
If we divide 89 by 12, we get 7 and a remainder of 5.
The next digit of our result is 7. 
Result so far: 31257.0
If we subtract 84 from 89, we get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 12

Step 7:
If we divide 53 by 12, we get 4 and a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 312574.0
Subtracting 48 from 53 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 12

Advancing to step 8:
12 goes into 50 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 3125744.0
Deduct 48 from 50 and we're left 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.

On to step 9:
When dividing 20 by 12, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 3125744.1
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.

Going ahead to step 10:
12 goes into 80 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 3125744.16
If we take 72 away from 80, we end up 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.

Going ahead to step 11:
12 goes into 80 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 3125744.166
If we subtract 72 from 80, we get 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 result is 3125744.166 with a remainder of 0.0008.
