Let's divide 31695720 by 210
The aim is to understand the frequency of 210 in 31695720.

Step 1:
210 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 210

On to step 2:
210 goes into 31 0 times with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 210

Moving on to step 3:
If we divide 316 by 210, we get 1 and a remainder of 106.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 210 from 316 to get 106.
Include the next digit (9) from the dividend after 106, then repeat: 1069 / 210

On to step 4:
210 goes into 1069 5 times with a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 1050 from 1069 leaves us with 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 210

On to step 5:
210 can be fit into 195 0 times, resulting in a remainder of 195.
Put 0 as the next digit of the answer. 
Result so far: 150.0
Subtract 0 from 195 to get 195.
Fetch the next digit (7) from the dividend, attach it to 195 and continue: 1957 / 210

Let's proceed to step 6:
If we divide 1957 by 210, we get 9 and a remainder of 67.
The next digit of our result is 9. 
Result so far: 1509.0
The remainder is 67 after subtracting 1890 from 1957.
Append the next digit (2) from the dividend to 67 and continue with: 672 / 210

On to step 7:
672 divided by 210 is 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 15093.0
The remainder is 42 after subtracting 630 from 672.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 210

Advancing to step 8:
The number 210 fits into 420 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 150932.0
The remainder is 0 after subtracting 420 from 420.
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:
0 divided by 210 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 150932.0
Deduct 0 from 0 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.

Advancing to step 10:
The number 210 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 150932.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 150932.0 with a remaining 0.0.
