We're dividing 69275472 by 210 
The aim is to understand the frequency of 210 in 69275472.

Let's proceed to step 1:
The number 210 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 210

On to step 2:
210 can be fit into 69 0 times, resulting in a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Append the next digit (2) from the dividend to 69 and continue with: 692 / 210

Let's proceed to step 3:
The number 210 fits into 692 3 times, leaving a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 630 from 692 leaves us with 62.
Include the next digit (7) from the dividend after 62, then repeat: 627 / 210

Going ahead to step 4:
When dividing 627 by 210, we get 2 with a remainder of 207.
Use 2 as the next digit of our solution. 
Result so far: 32.0
The remainder is 207 after subtracting 420 from 627.
Include the next digit (5) from the dividend after 207, then repeat: 2075 / 210

Moving on to step 5:
If we divide 2075 by 210, we get 9 and a remainder of 185.
Put 9 as the next digit of the answer. 
Result so far: 329.0
Deduct 1890 from 2075 and we're left with 185.
Take the next digit (4) from the dividend and append it to 185, then repeat: 1854 / 210

Going ahead to step 6:
210 can be fit into 1854 8 times, resulting in a remainder of 174.
The number 8 becomes the next digit in our result. 
Result so far: 3298.0
Subtracting 1680 from 1854 leaves us with 174.
Include the next digit (7) from the dividend after 174, then repeat: 1747 / 210

Advancing to step 7:
210 goes into 1747 8 times with a remainder of 67.
The next digit of our result is 8. 
Result so far: 32988.0
The remainder is 67 after subtracting 1680 from 1747.
Append the next digit (2) from the dividend to 67 and continue with: 672 / 210

Moving on to step 8:
When dividing 672 by 210, we get 3 with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 329883.0
If we take 630 away from 672, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
210 can be fit into 420 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 329883.2
Deduct 420 from 420 and we're left 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.

Going ahead to step 10:
When dividing 0 by 210, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 329883.2
Subtracting 0 from 0 leaves us 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.

Moving on to step 11:
If we divide 0 by 210, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 329883.2
The remainder is 0 after subtracting 0 from 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 final outcome is 329883.2, with a leftover of 0.0.
