654451 ÷ 12 
We want to divide 654451 by 12.

On to step 1:
6 divided by 12 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 12

Let's proceed to step 2:
If we divide 65 by 12, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 60 from 65 to get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 12

On to step 3:
54 divided by 12 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 54.0
If we take 48 away from 54, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 12

Step 4:
If we divide 64 by 12, we get 5 and a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 545.0
Subtract 60 from 64 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 12

Going ahead to step 5:
12 goes into 45 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 5453.0
Subtract 36 from 45 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 12

Moving on to step 6:
12 goes into 91 7 times with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 54537.0
Subtract 84 from 91 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
70 divided by 12 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 54537.5
Deduct 60 from 70 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
When dividing 100 by 12, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 54537.58
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
When dividing 40 by 12, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 54537.583
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.

Let's proceed to step 10:
When dividing 40 by 12, we get 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 54537.5833
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 result is 54537.5833 with a remainder of 4e-05.
