7623294 divided by 210 
The aim is to understand the frequency of 210 in 7623294.

On to step 1:
If we divide 7 by 210, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 210

Let's proceed to step 2:
If we divide 76 by 210, we get 0 and a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Append the next digit (2) from the dividend to 76 and continue with: 762 / 210

Step 3:
The number 210 fits into 762 3 times, leaving a remainder of 132.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 630 from 762 and we're left with 132.
Take the next digit (3) from the dividend and append it to 132, then repeat: 1323 / 210

Going ahead to step 4:
210 can be fit into 1323 6 times, resulting in a remainder of 63.
The next digit of our result is 6. 
Result so far: 36.0
Subtract 1260 from 1323 to get 63.
Take the next digit (2) from the dividend and append it to 63, then repeat: 632 / 210

Advancing to step 5:
632 divided by 210 is 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 363.0
Subtracting 630 from 632 leaves us with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 210

Step 6:
29 divided by 210 is 0 with a remainder of 29.
The next digit of our result is 0. 
Result so far: 3630.0
The remainder is 29 after subtracting 0 from 29.
Bring next digit (4) of the dividend behind the 29 and repeat the process: 294 / 210

Let's proceed to step 7:
The number 210 fits into 294 1 times, leaving a remainder of 84.
Use 1 as the next digit of our solution. 
Result so far: 36301.0
Subtract 210 from 294 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 8:
When dividing 840 by 210, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 36301.4
Subtracting 840 from 840 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 9:
210 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 36301.4
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 10:
If we divide 0 by 210, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 36301.4
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.

In conclusion, the division gives 36301.4 with a balance of 0.0.
