We divide 68382923 by 210
The aim is to understand the frequency of 210 in 68382923.

Step 1:
If we divide 6 by 210, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 210

Moving on to step 2:
68 divided by 210 is 0 with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Fetch the next digit (3) from the dividend, attach it to 68 and continue: 683 / 210

Step 3:
The number 210 fits into 683 3 times, leaving a remainder of 53.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 630 from 683 and we're left with 53.
Include the next digit (8) from the dividend after 53, then repeat: 538 / 210

Step 4:
210 can be fit into 538 2 times, resulting in a remainder of 118.
The next digit of our result is 2. 
Result so far: 32.0
Subtracting 420 from 538 leaves us with 118.
Append the next digit (2) from the dividend to 118 and continue with: 1182 / 210

On to step 5:
1182 divided by 210 is 5 with a remainder of 132.
Write down 5 as next digit of the result. 
Result so far: 325.0
Subtract 1050 from 1182 to get 132.
Include the next digit (9) from the dividend after 132, then repeat: 1329 / 210

Let's proceed to step 6:
If we divide 1329 by 210, we get 6 and a remainder of 69.
Use 6 as the next digit of our solution. 
Result so far: 3256.0
The remainder is 69 after subtracting 1260 from 1329.
Include the next digit (2) from the dividend after 69, then repeat: 692 / 210

Moving on to step 7:
When dividing 692 by 210, we get 3 with a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 32563.0
If we take 630 away from 692, we end up with 62.
Grab the next digit (3) from the dividend, add it to 62, then carry on: 623 / 210

Going ahead to step 8:
210 goes into 623 2 times with a remainder of 203.
Record the quotient 2 as the next digit in the result. 
Result so far: 325632.0
Deduct 420 from 623 and we're left with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Moving on to step 9:
If we divide 2030 by 210, we get 9 and a remainder of 140.
Record the quotient 9 as the next digit in the result. 
Result so far: 325632.9
If we subtract 1890 from 2030, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 10:
210 goes into 1400 6 times with a remainder of 140.
Record the quotient 6 as the next digit in the result. 
Result so far: 325632.96
If we subtract 1260 from 1400, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 11:
1400 divided by 210 is 6 with a remainder of 140.
Use 6 as the next digit of our solution. 
Result so far: 325632.966
Subtract 1260 from 1400 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

After the division, we end up with 325632.966 and a remainder of 0.014.
