We're dividing 65938091 by 175 
The aim is to understand the frequency of 175 in 65938091.

Advancing to step 1:
175 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 175

On to step 2:
175 goes into 65 0 times with a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Include the next digit (9) from the dividend after 65, then repeat: 659 / 175

Step 3:
175 goes into 659 3 times with a remainder of 134.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 525 from 659 leaves us with 134.
Append the next digit (3) from the dividend to 134 and continue with: 1343 / 175

Step 4:
When dividing 1343 by 175, we get 7 with a remainder of 118.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Deduct 1225 from 1343 and we're left with 118.
Append the next digit (8) from the dividend to 118 and continue with: 1188 / 175

Step 5:
When dividing 1188 by 175, we get 6 with a remainder of 138.
The next digit of our result is 6. 
Result so far: 376.0
Deduct 1050 from 1188 and we're left with 138.
Append the next digit (0) from the dividend to 138 and continue with: 1380 / 175

On to step 6:
When dividing 1380 by 175, we get 7 with a remainder of 155.
Put 7 as the next digit of the answer. 
Result so far: 3767.0
Deduct 1225 from 1380 and we're left with 155.
Take the next digit (9) from the dividend and append it to 155, then repeat: 1559 / 175

Going ahead to step 7:
175 goes into 1559 8 times with a remainder of 159.
Use 8 as the next digit of our solution. 
Result so far: 37678.0
Subtracting 1400 from 1559 leaves us with 159.
Bring next digit (1) of the dividend behind the 159 and repeat the process: 1591 / 175

Advancing to step 8:
If we divide 1591 by 175, we get 9 and a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 376789.0
Subtracting 1575 from 1591 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.

Moving on to step 9:
When dividing 160 by 175, we get 0 with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 376789.0
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 10:
When dividing 1600 by 175, we get 9 with a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 376789.09
Deduct 1575 from 1600 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
When dividing 250 by 175, we get 1 with a remainder of 75.
Write down 1 as next digit of the result. 
Result so far: 376789.091
Deduct 175 from 250 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 12:
175 goes into 750 4 times with a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 376789.0914
Deduct 700 from 750 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
175 can be fit into 500 2 times, resulting in a remainder of 150.
Put 2 as the next digit of the answer. 
Result so far: 376789.09142
Subtract 350 from 500 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 14:
The number 175 fits into 1500 8 times, leaving a remainder of 100.
Use 8 as the next digit of our solution. 
Result so far: 376789.091428
If we subtract 1400 from 1500, 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.

Advancing to step 15:
175 goes into 1000 5 times with a remainder of 125.
The next digit of our result is 5. 
Result so far: 376789.0914285
Deduct 875 from 1000 and we're left with 125.
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 16:
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: 376789.09142857
Deduct 1225 from 1250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 376789.09142857 with a remainder of 2.5e-08.
