Let's divide 730091 by 12
The aim is to understand the frequency of 12 in 730091.

Advancing to step 1:
7 divided by 12 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 12

Going ahead to step 2:
73 divided by 12 is 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 72 away from 73, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 12

Going ahead to step 3:
12 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
Subtract 0 from 10 to get 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 12

Moving on to step 4:
The number 12 fits into 100 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 608.0
Subtracting 96 from 100 leaves us with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 12

Advancing to step 5:
49 divided by 12 is 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 6084.0
Subtract 48 from 49 to get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 12

Advancing to step 6:
12 goes into 11 0 times with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 60840.0
Deduct 0 from 11 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
The number 12 fits into 110 9 times, leaving a remainder of 2.
The next digit of our result is 9. 
Result so far: 60840.9
Subtracting 108 from 110 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
If we divide 20 by 12, we get 1 and a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 60840.91
Deduct 12 from 20 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 60840.916
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 60840.9166
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 60840.9166 with a remaining 8e-05.
