We divide 81799002 by 209
The aim is to understand the frequency of 209 in 81799002.

Step 1:
209 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 209

Going ahead to step 2:
When dividing 81 by 209, we get 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Bring next digit (7) of the dividend behind the 81 and repeat the process: 817 / 209

Step 3:
209 goes into 817 3 times with a remainder of 190.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 627 from 817 to get 190.
Take the next digit (9) from the dividend and append it to 190, then repeat: 1909 / 209

Moving on to step 4:
If we divide 1909 by 209, we get 9 and a remainder of 28.
The next digit of our result is 9. 
Result so far: 39.0
The remainder is 28 after subtracting 1881 from 1909.
Take the next digit (9) from the dividend and append it to 28, then repeat: 289 / 209

Going ahead to step 5:
209 goes into 289 1 times with a remainder of 80.
The next digit of our result is 1. 
Result so far: 391.0
Deduct 209 from 289 and we're left with 80.
Append the next digit (0) from the dividend to 80 and continue with: 800 / 209

Going ahead to step 6:
If we divide 800 by 209, we get 3 and a remainder of 173.
Use 3 as the next digit of our solution. 
Result so far: 3913.0
Subtracting 627 from 800 leaves us with 173.
Grab the next digit (0) from the dividend, add it to 173, then carry on: 1730 / 209

Moving on to step 7:
209 can be fit into 1730 8 times, resulting in a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 39138.0
If we subtract 1672 from 1730, we get 58.
Grab the next digit (2) from the dividend, add it to 58, then carry on: 582 / 209

Moving on to step 8:
209 goes into 582 2 times with a remainder of 164.
Write down 2 as next digit of the result. 
Result so far: 391382.0
Subtract 418 from 582 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 9:
209 goes into 1640 7 times with a remainder of 177.
Write down 7 as next digit of the result. 
Result so far: 391382.7
The remainder is 177 after subtracting 1463 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Going ahead to step 10:
1770 divided by 209 is 8 with a remainder of 98.
Record the quotient 8 as the next digit in the result. 
Result so far: 391382.78
If we take 1672 away from 1770, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 11:
When dividing 980 by 209, we get 4 with a remainder of 144.
Put 4 as the next digit of the answer. 
Result so far: 391382.784
The remainder is 144 after subtracting 836 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 12:
When dividing 1440 by 209, we get 6 with a remainder of 186.
Put 6 as the next digit of the answer. 
Result so far: 391382.7846
Subtracting 1254 from 1440 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 13:
The number 209 fits into 1860 8 times, leaving a remainder of 188.
The number 8 becomes the next digit in our result. 
Result so far: 391382.78468
The remainder is 188 after subtracting 1672 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 14:
If we divide 1880 by 209, we get 8 and a remainder of 208.
The next digit of our result is 8. 
Result so far: 391382.784688
The remainder is 208 after subtracting 1672 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

In conclusion, the division gives 391382.784688 with a balance of 2.08e-05.
