68241457 ÷ 12 
We want to divide 68241457 by 12.

On to step 1:
6 divided by 12 is 0 with 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.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 12

Moving on to step 2:
68 divided by 12 is 5 with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 60 from 68 to get 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 12

On to step 3:
When dividing 82 by 12, we get 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 56.0
Deduct 72 from 82 and we're left with 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 12

Step 4:
When dividing 104 by 12, we get 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 568.0
If we take 96 away from 104, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 12

Step 5:
12 can be fit into 81 6 times, resulting in a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 5686.0
Deduct 72 from 81 and we're left with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 12

On to step 6:
The number 12 fits into 94 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 56867.0
Subtract 84 from 94 to get 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 12

Step 7:
12 can be fit into 105 8 times, resulting in a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 568678.0
If we subtract 96 from 105, we get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 12

Step 8:
97 divided by 12 is 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 5686788.0
If we subtract 96 from 97, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
If we divide 10 by 12, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 5686788.0
If we subtract 0 from 10, we get 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 10:
If we divide 100 by 12, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 5686788.08
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.

On to step 11:
12 can be fit into 40 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 5686788.083
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.

Moving on to step 12:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 5686788.0833
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 5686788.0833 with a balance of 4e-05.
