We're dividing 55550463 by 12 
The aim is to understand the frequency of 12 in 55550463.

Advancing to step 1:
When dividing 5 by 12, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 12

Moving on to step 2:
12 goes into 55 4 times with a remainder of 7.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 7 after subtracting 48 from 55.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 12

Advancing to step 3:
12 can be fit into 75 6 times, resulting in a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 46.0
The remainder is 3 after subtracting 72 from 75.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 12

On to step 4:
12 goes into 35 2 times with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 462.0
Deduct 24 from 35 and we're left with 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 12

Advancing to step 5:
110 divided by 12 is 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 4629.0
Deduct 108 from 110 and we're left with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 12

Going ahead to step 6:
The number 12 fits into 24 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 46292.0
The remainder is 0 after subtracting 24 from 24.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 12

Moving on to step 7:
When dividing 6 by 12, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 462920.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 12

Going ahead to step 8:
12 goes into 63 5 times with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 4629205.0
If we subtract 60 from 63, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
If we divide 30 by 12, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 4629205.2
If we take 24 away from 30, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
The number 12 fits into 60 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 4629205.25
If we take 60 away from 60, we end up 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 11:
12 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4629205.25
Subtract 0 from 0 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.

Moving on to step 12:
When dividing 0 by 12, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4629205.25
If we take 0 away from 0, we end up 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.

The quotient of the division is 4629205.25, and the remainder is 0.0.
