34516570 ÷ 12 
Our goal is to divide 34516570 by 12.

Moving on to step 1:
3 divided by 12 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 12

Step 2:
The number 12 fits into 34 2 times, leaving a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 24 from 34 to get 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 12

Moving on to step 3:
12 can be fit into 105 8 times, resulting in a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtract 96 from 105 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 12

Moving on to step 4:
The number 12 fits into 91 7 times, leaving a remainder of 7.
The next digit of our result is 7. 
Result so far: 287.0
Subtracting 84 from 91 leaves us with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 12

Moving on to step 5:
76 divided by 12 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 2876.0
Deduct 72 from 76 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 12

Let's proceed to step 6:
45 divided by 12 is 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 28763.0
If we subtract 36 from 45, we get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 12

Advancing to step 7:
The number 12 fits into 97 8 times, leaving a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 287638.0
Subtracting 96 from 97 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 12

Step 8:
The number 12 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 2876380.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 2876380.8
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.

Going ahead to step 10:
40 divided by 12 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 2876380.83
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.

Let's proceed to step 11:
40 divided by 12 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 2876380.833
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.

In conclusion, the division gives 2876380.833 with a balance of 0.0004.
