We look at the division of 17417724 by 202 
The aim is to understand the frequency of 202 in 17417724.

On to step 1:
When dividing 1 by 202, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 202

Going ahead to step 2:
The number 202 fits into 17 0 times, leaving a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 202

Going ahead to step 3:
202 can be fit into 174 0 times, resulting in a remainder of 174.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 174 and we're left with 174.
Grab the next digit (1) from the dividend, add it to 174, then carry on: 1741 / 202

Step 4:
1741 divided by 202 is 8 with a remainder of 125.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 1616 from 1741 to get 125.
Include the next digit (7) from the dividend after 125, then repeat: 1257 / 202

Step 5:
202 can be fit into 1257 6 times, resulting in a remainder of 45.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
The remainder is 45 after subtracting 1212 from 1257.
Append the next digit (7) from the dividend to 45 and continue with: 457 / 202

Step 6:
The number 202 fits into 457 2 times, leaving a remainder of 53.
Put 2 as the next digit of the answer. 
Result so far: 862.0
If we take 404 away from 457, we end up with 53.
Take the next digit (2) from the dividend and append it to 53, then repeat: 532 / 202

Let's proceed to step 7:
The number 202 fits into 532 2 times, leaving a remainder of 128.
Use 2 as the next digit of our solution. 
Result so far: 8622.0
Subtract 404 from 532 to get 128.
Fetch the next digit (4) from the dividend, attach it to 128 and continue: 1284 / 202

Step 8:
202 goes into 1284 6 times with a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 86226.0
Subtract 1212 from 1284 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 9:
The number 202 fits into 720 3 times, leaving a remainder of 114.
The number 3 becomes the next digit in our result. 
Result so far: 86226.3
If we take 606 away from 720, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 10:
If we divide 1140 by 202, we get 5 and a remainder of 130.
Record the quotient 5 as the next digit in the result. 
Result so far: 86226.35
Subtract 1010 from 1140 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 11:
1300 divided by 202 is 6 with a remainder of 88.
Put 6 as the next digit of the answer. 
Result so far: 86226.356
If we subtract 1212 from 1300, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 12:
202 goes into 880 4 times with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 86226.3564
If we subtract 808 from 880, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 13:
202 can be fit into 720 3 times, resulting in a remainder of 114.
Put 3 as the next digit of the answer. 
Result so far: 86226.35643
The remainder is 114 after subtracting 606 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 14:
1140 divided by 202 is 5 with a remainder of 130.
The next digit of our result is 5. 
Result so far: 86226.356435
Subtracting 1010 from 1140 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 15:
When dividing 1300 by 202, we get 6 with a remainder of 88.
Put 6 as the next digit of the answer. 
Result so far: 86226.3564356
If we subtract 1212 from 1300, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 16:
The number 202 fits into 880 4 times, leaving a remainder of 72.
The next digit of our result is 4. 
Result so far: 86226.35643564
Deduct 808 from 880 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 86226.35643564 with a remainder of 7.2e-08.
