We look at the division of 751807 by 12 
The aim is to understand the frequency of 12 in 751807.

Step 1:
The number 12 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 12

Let's proceed to step 2:
The number 12 fits into 75 6 times, leaving a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 72 from 75 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 12

Moving on to step 3:
31 divided by 12 is 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 62.0
Subtract 24 from 31 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 12

On to step 4:
78 divided by 12 is 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 626.0
Subtracting 72 from 78 leaves us with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 12

Moving on to step 5:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 6265.0
If we take 60 away from 60, we end up with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 12

Step 6:
12 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 62650.0
If we subtract 0 from 7, we 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.

Let's proceed to step 7:
If we divide 70 by 12, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 62650.5
The remainder is 10 after subtracting 60 from 70.
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:
If we divide 100 by 12, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 62650.58
If we take 96 away from 100, 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 9:
40 divided by 12 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 62650.583
Subtract 36 from 40 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.

On to step 10:
40 divided by 12 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 62650.5833
Deduct 36 from 40 and we're left 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 outcome is 62650.5833, with a leftover of 4e-05.
