We divide 725583 by 12
The aim is to understand the frequency of 12 in 725583.

Step 1:
When dividing 7 by 12, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 12

Let's proceed to step 2:
When dividing 72 by 12, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 72 from 72 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 12

Advancing to step 3:
12 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
If we subtract 0 from 5, we get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 12

Let's proceed to step 4:
When dividing 55 by 12, we get 4 with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 604.0
Subtract 48 from 55 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 12

Let's proceed to step 5:
12 goes into 78 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 6046.0
Deduct 72 from 78 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 12

Advancing to step 6:
12 can be fit into 63 5 times, resulting in a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 60465.0
Subtracting 60 from 63 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.

Let's proceed to step 7:
30 divided by 12 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 60465.2
Subtract 24 from 30 to 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.

Advancing to step 8:
12 goes into 60 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 60465.25
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.

Let's proceed to step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 60465.25
Deduct 0 from 0 and we're left 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.

On to step 10:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 60465.25
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 60465.25, and the remainder is 0.0.
