68042370 divided by 12 
We're looking to find how many times 12 goes into 68042370.

Step 1:
12 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 12

Step 2:
12 can be fit into 68 5 times, resulting in a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 8 after subtracting 60 from 68.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 12

Step 3:
If we divide 80 by 12, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
If we take 72 away from 80, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 12

Moving on to step 4:
84 divided by 12 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 567.0
Deduct 84 from 84 and we're left with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 12

Going ahead to step 5:
2 divided by 12 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 5670.0
If we subtract 0 from 2, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 12

Moving on to step 6:
12 goes into 23 1 times with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 56701.0
Subtract 12 from 23 to get 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 12

Going ahead to step 7:
117 divided by 12 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 567019.0
Deduct 108 from 117 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 12

Step 8:
When dividing 90 by 12, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 5670197.0
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
When dividing 60 by 12, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5670197.5
If we subtract 60 from 60, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
When dividing 0 by 12, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5670197.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
If we divide 0 by 12, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5670197.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 5670197.5, and the remainder is 0.0.
