653394 ÷ 12 
We want to figure out the number of times 653394 can be divided by 12.

Advancing to step 1:
12 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 12

On to step 2:
The number 12 fits into 65 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 60 from 65 to get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 12

Step 3:
12 goes into 53 4 times with a remainder of 5.
The next digit of our result is 4. 
Result so far: 54.0
Subtract 48 from 53 to get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 12

Going ahead to step 4:
12 goes into 53 4 times with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 544.0
Subtracting 48 from 53 leaves us with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 12

On to step 5:
12 goes into 59 4 times with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 5444.0
Subtract 48 from 59 to get 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 12

Moving on to step 6:
If we divide 114 by 12, we get 9 and a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 54449.0
Deduct 108 from 114 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
60 divided by 12 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 54449.5
Subtract 60 from 60 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.

Step 8:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 54449.5
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.

Step 9:
12 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 54449.5
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 final outcome is 54449.5, with a leftover of 0.0.
