We look at the division of 96093894 by 210 
The aim is to understand the frequency of 210 in 96093894.

Advancing to step 1:
210 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 210

Let's proceed to step 2:
When dividing 96 by 210, we get 0 with a remainder of 96.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 96 after subtracting 0 from 96.
Fetch the next digit (0) from the dividend, attach it to 96 and continue: 960 / 210

Advancing to step 3:
960 divided by 210 is 4 with a remainder of 120.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 840 from 960 leaves us with 120.
Take the next digit (9) from the dividend and append it to 120, then repeat: 1209 / 210

Moving on to step 4:
The number 210 fits into 1209 5 times, leaving a remainder of 159.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtract 1050 from 1209 to get 159.
Include the next digit (3) from the dividend after 159, then repeat: 1593 / 210

Going ahead to step 5:
1593 divided by 210 is 7 with a remainder of 123.
The number 7 becomes the next digit in our result. 
Result so far: 457.0
Deduct 1470 from 1593 and we're left with 123.
Include the next digit (8) from the dividend after 123, then repeat: 1238 / 210

Step 6:
210 can be fit into 1238 5 times, resulting in a remainder of 188.
Put 5 as the next digit of the answer. 
Result so far: 4575.0
If we subtract 1050 from 1238, we get 188.
Grab the next digit (9) from the dividend, add it to 188, then carry on: 1889 / 210

Going ahead to step 7:
1889 divided by 210 is 8 with a remainder of 209.
Put 8 as the next digit of the answer. 
Result so far: 45758.0
Subtract 1680 from 1889 to get 209.
Take the next digit (4) from the dividend and append it to 209, then repeat: 2094 / 210

Moving on to step 8:
The number 210 fits into 2094 9 times, leaving a remainder of 204.
Put 9 as the next digit of the answer. 
Result so far: 457589.0
If we subtract 1890 from 2094, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 9:
210 can be fit into 2040 9 times, resulting in a remainder of 150.
The next digit of our result is 9. 
Result so far: 457589.9
Deduct 1890 from 2040 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 10:
When dividing 1500 by 210, we get 7 with a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 457589.97
If we subtract 1470 from 1500, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
210 can be fit into 300 1 times, resulting in a remainder of 90.
Use 1 as the next digit of our solution. 
Result so far: 457589.971
The remainder is 90 after subtracting 210 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 12:
210 goes into 900 4 times with a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 457589.9714
The remainder is 60 after subtracting 840 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
When dividing 600 by 210, we get 2 with a remainder of 180.
Use 2 as the next digit of our solution. 
Result so far: 457589.97142
The remainder is 180 after subtracting 420 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 14:
The number 210 fits into 1800 8 times, leaving a remainder of 120.
Use 8 as the next digit of our solution. 
Result so far: 457589.971428
Subtracting 1680 from 1800 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 15:
The number 210 fits into 1200 5 times, leaving a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 457589.9714285
Subtracting 1050 from 1200 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 16:
210 goes into 1500 7 times with a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 457589.97142857
Subtract 1470 from 1500 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 457589.97142857 with a remainder of 3e-08.
