We divide 17390931 by 209
The aim is to understand the frequency of 209 in 17390931.

Advancing to step 1:
209 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 209

Let's proceed to step 2:
When dividing 17 by 209, we get 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 209

On to step 3:
When dividing 173 by 209, we get 0 with a remainder of 173.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 173, we get 173.
Include the next digit (9) from the dividend after 173, then repeat: 1739 / 209

Going ahead to step 4:
209 can be fit into 1739 8 times, resulting in a remainder of 67.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 1672 from 1739 leaves us with 67.
Fetch the next digit (0) from the dividend, attach it to 67 and continue: 670 / 209

Moving on to step 5:
If we divide 670 by 209, we get 3 and a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Subtracting 627 from 670 leaves us with 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 209

Let's proceed to step 6:
If we divide 439 by 209, we get 2 and a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 832.0
If we subtract 418 from 439, we get 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 209

Let's proceed to step 7:
209 goes into 213 1 times with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 8321.0
Subtracting 209 from 213 leaves us with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 209

On to step 8:
The number 209 fits into 41 0 times, leaving a remainder of 41.
The next digit of our result is 0. 
Result so far: 83210.0
If we subtract 0 from 41, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 9:
If we divide 410 by 209, we get 1 and a remainder of 201.
Record the quotient 1 as the next digit in the result. 
Result so far: 83210.1
If we take 209 away from 410, we end up with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Advancing to step 10:
When dividing 2010 by 209, we get 9 with a remainder of 129.
Use 9 as the next digit of our solution. 
Result so far: 83210.19
Subtract 1881 from 2010 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Advancing to step 11:
209 can be fit into 1290 6 times, resulting in a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 83210.196
If we subtract 1254 from 1290, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
If we divide 360 by 209, we get 1 and a remainder of 151.
Write down 1 as next digit of the result. 
Result so far: 83210.1961
If we subtract 209 from 360, we get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Step 13:
209 goes into 1510 7 times with a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 83210.19617
Subtract 1463 from 1510 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 14:
209 goes into 470 2 times with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 83210.196172
If we subtract 418 from 470, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 15:
209 goes into 520 2 times with a remainder of 102.
Use 2 as the next digit of our solution. 
Result so far: 83210.1961722
If we take 418 away from 520, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

After the division, we end up with 83210.1961722 and a remainder of 1.02e-06.
