We divide 17186221 by 175
The aim is to understand the frequency of 175 in 17186221.

Step 1:
If we divide 1 by 175, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 175

Advancing to step 2:
175 goes into 17 0 times with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 175

Step 3:
If we divide 171 by 175, we get 0 and a remainder of 171.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 171, we end up with 171.
Include the next digit (8) from the dividend after 171, then repeat: 1718 / 175

On to step 4:
The number 175 fits into 1718 9 times, leaving a remainder of 143.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 1575 from 1718 and we're left with 143.
Append the next digit (6) from the dividend to 143 and continue with: 1436 / 175

Moving on to step 5:
If we divide 1436 by 175, we get 8 and a remainder of 36.
The next digit of our result is 8. 
Result so far: 98.0
If we subtract 1400 from 1436, we get 36.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 175

Step 6:
If we divide 362 by 175, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 982.0
If we take 350 away from 362, we end up with 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 175

On to step 7:
The number 175 fits into 122 0 times, leaving a remainder of 122.
Put 0 as the next digit of the answer. 
Result so far: 9820.0
If we take 0 away from 122, we end up with 122.
Include the next digit (1) from the dividend after 122, then repeat: 1221 / 175

Let's proceed to step 8:
175 can be fit into 1221 6 times, resulting in a remainder of 171.
The number 6 becomes the next digit in our result. 
Result so far: 98206.0
If we subtract 1050 from 1221, we get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Let's proceed to step 9:
The number 175 fits into 1710 9 times, leaving a remainder of 135.
Use 9 as the next digit of our solution. 
Result so far: 98206.9
Subtracting 1575 from 1710 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 10:
175 goes into 1350 7 times with a remainder of 125.
The next digit of our result is 7. 
Result so far: 98206.97
The remainder is 125 after subtracting 1225 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 11:
The number 175 fits into 1250 7 times, leaving a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 98206.977
The remainder is 25 after subtracting 1225 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 98206.977, and the remainder is 0.0025.
