601455 divided by 12 
Let's see how many times 12 fits into 601455.

On to step 1:
12 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 12

On to step 2:
If we divide 60 by 12, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 60 away from 60, we end up with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 12

Step 3:
12 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Subtract 0 from 1 to get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 12

Step 4:
14 divided by 12 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 501.0
If we subtract 12 from 14, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 12

Let's proceed to step 5:
12 goes into 25 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 5012.0
If we take 24 away from 25, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 12

Going ahead to step 6:
15 divided by 12 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 50121.0
Subtracting 12 from 15 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
The number 12 fits into 30 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 50121.2
If we subtract 24 from 30, 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.

Moving on to step 8:
If we divide 60 by 12, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 50121.25
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.

Advancing to step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 50121.25
Subtracting 0 from 0 leaves us with 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.
Record the quotient 0 as the next digit in the result. 
Result so far: 50121.25
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.

The final result is 50121.25 with a remainder of 0.0.
