30520702 divided by 12 
We want to figure out the number of times 30520702 can be divided by 12.

Going ahead to step 1:
If we divide 3 by 12, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 12

Moving on to step 2:
When dividing 30 by 12, we get 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 24 from 30 leaves us with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 12

Moving on to step 3:
12 can be fit into 65 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 60 from 65 and we're left with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 12

On to step 4:
If we divide 52 by 12, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 254.0
Deduct 48 from 52 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 12

Step 5:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 2543.0
Subtract 36 from 40 to get 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 12

Going ahead to step 6:
12 can be fit into 47 3 times, resulting in a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 25433.0
If we take 36 away from 47, we end up with 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 12

Let's proceed to step 7:
12 goes into 110 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 254339.0
If we subtract 108 from 110, we get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 12

On to step 8:
22 divided by 12 is 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 2543391.0
The remainder is 10 after subtracting 12 from 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
When dividing 100 by 12, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 2543391.8
If we take 96 away from 100, 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.

Moving on to step 10:
12 goes into 40 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 2543391.83
Subtract 36 from 40 to 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.

Moving on to step 11:
40 divided by 12 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 2543391.833
Subtracting 36 from 40 leaves us 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 2543391.833, with a leftover of 0.0004.
