723037 ÷ 12 
The aim is to understand the frequency of 12 in 723037.

Moving on to step 1:
If we divide 7 by 12, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 12

Moving on to step 2:
If we divide 72 by 12, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 72 from 72 to get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 12

Step 3:
12 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 12

Going ahead to step 4:
12 goes into 30 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 602.0
Subtracting 24 from 30 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 12

Moving on to step 5:
If we divide 63 by 12, we get 5 and a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 6025.0
Subtracting 60 from 63 leaves us with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 12

Step 6:
If we divide 37 by 12, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 60253.0
The remainder is 1 after subtracting 36 from 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
12 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 60253.0
If we take 0 away from 10, we end up 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.

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: 60253.08
Subtract 96 from 100 to 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.

Going ahead to step 9:
12 goes into 40 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 60253.083
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.

Moving on to step 10:
If we divide 40 by 12, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 60253.0833
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.

The final result is 60253.0833 with a remainder of 4e-05.
