17099988 divided by 208 
The aim is to understand the frequency of 208 in 17099988.

On to step 1:
208 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 208

Step 2:
When dividing 17 by 208, we get 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 208

On to step 3:
The number 208 fits into 170 0 times, leaving a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 170 after subtracting 0 from 170.
Bring next digit (9) of the dividend behind the 170 and repeat the process: 1709 / 208

Let's proceed to step 4:
If we divide 1709 by 208, we get 8 and a remainder of 45.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 45 after subtracting 1664 from 1709.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 208

Let's proceed to step 5:
208 can be fit into 459 2 times, resulting in a remainder of 43.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
If we take 416 away from 459, we end up with 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 208

Going ahead to step 6:
208 can be fit into 439 2 times, resulting in a remainder of 23.
The next digit of our result is 2. 
Result so far: 822.0
If we take 416 away from 439, we end up with 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 208

Step 7:
208 goes into 238 1 times with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 8221.0
The remainder is 30 after subtracting 208 from 238.
Append the next digit (8) from the dividend to 30 and continue with: 308 / 208

Step 8:
If we divide 308 by 208, we get 1 and a remainder of 100.
Use 1 as the next digit of our solution. 
Result so far: 82211.0
If we subtract 208 from 308, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 9:
1000 divided by 208 is 4 with a remainder of 168.
Record the quotient 4 as the next digit in the result. 
Result so far: 82211.4
Subtract 832 from 1000 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 10:
1680 divided by 208 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 82211.48
Subtracting 1664 from 1680 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
160 divided by 208 is 0 with a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 82211.48
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 12:
The number 208 fits into 1600 7 times, leaving a remainder of 144.
The next digit of our result is 7. 
Result so far: 82211.4807
The remainder is 144 after subtracting 1456 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 13:
208 can be fit into 1440 6 times, resulting in a remainder of 192.
The number 6 becomes the next digit in our result. 
Result so far: 82211.48076
Subtracting 1248 from 1440 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 14:
208 can be fit into 1920 9 times, resulting in a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 82211.480769
The remainder is 48 after subtracting 1872 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 15:
If we divide 480 by 208, we get 2 and a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 82211.4807692
Subtract 416 from 480 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 16:
The number 208 fits into 640 3 times, leaving a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 82211.48076923
Subtracting 624 from 640 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 82211.48076923 and a remainder of 1.6e-08.
