We divide 621485 by 12
The aim is to understand the frequency of 12 in 621485.

Moving on to step 1:
The number 12 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 12

On to step 2:
62 divided by 12 is 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 2 after subtracting 60 from 62.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 12

On to step 3:
12 goes into 21 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
The remainder is 9 after subtracting 12 from 21.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 12

Step 4:
94 divided by 12 is 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 517.0
If we subtract 84 from 94, we get 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 12

Going ahead to step 5:
The number 12 fits into 108 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 5179.0
If we take 108 away from 108, we end up with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 12

Moving on to step 6:
When dividing 5 by 12, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 51790.0
The remainder is 5 after subtracting 0 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
50 divided by 12 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 51790.4
Deduct 48 from 50 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.

Advancing to step 8:
12 goes into 20 1 times with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 51790.41
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.

Advancing to step 9:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 51790.416
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:
When dividing 80 by 12, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 51790.4166
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.

In conclusion, the division gives 51790.4166 with a balance of 8e-05.
