We're dividing 14024638 by 210 
The aim is to understand the frequency of 210 in 14024638.

Moving on to step 1:
210 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 210

On to step 2:
210 can be fit into 14 0 times, resulting in a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 210

On to step 3:
If we divide 140 by 210, we get 0 and a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 140 to get 140.
Grab the next digit (2) from the dividend, add it to 140, then carry on: 1402 / 210

Moving on to step 4:
1402 divided by 210 is 6 with a remainder of 142.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 1260 from 1402, we get 142.
Grab the next digit (4) from the dividend, add it to 142, then carry on: 1424 / 210

Advancing to step 5:
The number 210 fits into 1424 6 times, leaving a remainder of 164.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Subtracting 1260 from 1424 leaves us with 164.
Bring next digit (6) of the dividend behind the 164 and repeat the process: 1646 / 210

Let's proceed to step 6:
The number 210 fits into 1646 7 times, leaving a remainder of 176.
The number 7 becomes the next digit in our result. 
Result so far: 667.0
Deduct 1470 from 1646 and we're left with 176.
Take the next digit (3) from the dividend and append it to 176, then repeat: 1763 / 210

Let's proceed to step 7:
When dividing 1763 by 210, we get 8 with a remainder of 83.
Write down 8 as next digit of the result. 
Result so far: 6678.0
Subtracting 1680 from 1763 leaves us with 83.
Append the next digit (8) from the dividend to 83 and continue with: 838 / 210

On to step 8:
When dividing 838 by 210, we get 3 with a remainder of 208.
Use 3 as the next digit of our solution. 
Result so far: 66783.0
If we subtract 630 from 838, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 9:
When dividing 2080 by 210, we get 9 with a remainder of 190.
Put 9 as the next digit of the answer. 
Result so far: 66783.9
Subtracting 1890 from 2080 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 10:
210 can be fit into 1900 9 times, resulting in a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 66783.99
If we subtract 1890 from 1900, 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.

The final result is 66783.99 with a remainder of 0.01.
