We divide 649646 by 12
The aim is to understand the frequency of 12 in 649646.

Going ahead to step 1:
The number 12 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 12

On to step 2:
The number 12 fits into 64 5 times, leaving a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 60 from 64 leaves us with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 12

Going ahead to step 3:
12 can be fit into 49 4 times, resulting in a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 54.0
Deduct 48 from 49 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 12

Step 4:
When dividing 16 by 12, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 541.0
Subtracting 12 from 16 leaves us with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 12

Going ahead to step 5:
When dividing 44 by 12, we get 3 with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 5413.0
Subtract 36 from 44 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 12

Advancing to step 6:
When dividing 86 by 12, we get 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 54137.0
Deduct 84 from 86 and we're left 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.

Let's proceed to step 7:
When dividing 20 by 12, we get 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 54137.1
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.

Moving on to step 8:
12 goes into 80 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 54137.16
Deduct 72 from 80 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:
80 divided by 12 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 54137.166
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.

The quotient of the division is 54137.166, and the remainder is 0.0008.
