548611 ÷ 12 
The aim is to understand the frequency of 12 in 548611.

On to step 1:
12 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 12

Let's proceed to step 2:
If we divide 54 by 12, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 48 from 54, we get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 12

Going ahead to step 3:
If we divide 68 by 12, we get 5 and a remainder of 8.
The next digit of our result is 5. 
Result so far: 45.0
The remainder is 8 after subtracting 60 from 68.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 12

Going ahead to step 4:
12 can be fit into 86 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 457.0
The remainder is 2 after subtracting 84 from 86.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 12

Moving on to step 5:
21 divided by 12 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 4571.0
If we take 12 away from 21, we end up with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 12

Advancing to step 6:
The number 12 fits into 91 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 45717.0
Subtracting 84 from 91 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
12 can be fit into 70 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 45717.5
If we subtract 60 from 70, we get 10.
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:
12 goes into 100 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 45717.58
Deduct 96 from 100 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.

Moving on to step 9:
If we divide 40 by 12, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 45717.583
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.

Advancing to step 10:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 45717.5833
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.

After the division, we end up with 45717.5833 and a remainder of 4e-05.
