We look at the division of 90578455 by 175 
The aim is to understand the frequency of 175 in 90578455.

Step 1:
The number 175 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 175

Moving on to step 2:
If we divide 90 by 175, we get 0 and a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Bring next digit (5) of the dividend behind the 90 and repeat the process: 905 / 175

Advancing to step 3:
The number 175 fits into 905 5 times, leaving a remainder of 30.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 875 from 905 and we're left with 30.
Take the next digit (7) from the dividend and append it to 30, then repeat: 307 / 175

Moving on to step 4:
175 can be fit into 307 1 times, resulting in a remainder of 132.
Put 1 as the next digit of the answer. 
Result so far: 51.0
If we take 175 away from 307, we end up with 132.
Grab the next digit (8) from the dividend, add it to 132, then carry on: 1328 / 175

Advancing to step 5:
175 can be fit into 1328 7 times, resulting in a remainder of 103.
Put 7 as the next digit of the answer. 
Result so far: 517.0
Subtracting 1225 from 1328 leaves us with 103.
Grab the next digit (4) from the dividend, add it to 103, then carry on: 1034 / 175

Step 6:
175 can be fit into 1034 5 times, resulting in a remainder of 159.
Put 5 as the next digit of the answer. 
Result so far: 5175.0
If we take 875 away from 1034, we end up with 159.
Append the next digit (5) from the dividend to 159 and continue with: 1595 / 175

Let's proceed to step 7:
175 can be fit into 1595 9 times, resulting in a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 51759.0
Deduct 1575 from 1595 and we're left with 20.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 175

Step 8:
175 can be fit into 205 1 times, resulting in a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 517591.0
If we take 175 away from 205, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
175 can be fit into 300 1 times, resulting in a remainder of 125.
Record the quotient 1 as the next digit in the result. 
Result so far: 517591.1
Deduct 175 from 300 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.

Step 10:
1250 divided by 175 is 7 with a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 517591.17
If we subtract 1225 from 1250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 11:
If we divide 250 by 175, we get 1 and a remainder of 75.
The next digit of our result is 1. 
Result so far: 517591.171
If we subtract 175 from 250, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 12:
If we divide 750 by 175, we get 4 and a remainder of 50.
Put 4 as the next digit of the answer. 
Result so far: 517591.1714
Subtracting 700 from 750 leaves us 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.

Advancing to step 13:
175 goes into 500 2 times with a remainder of 150.
Record the quotient 2 as the next digit in the result. 
Result so far: 517591.17142
Subtracting 350 from 500 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 14:
175 goes into 1500 8 times with a remainder of 100.
Put 8 as the next digit of the answer. 
Result so far: 517591.171428
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.

Moving on to step 15:
When dividing 1000 by 175, we get 5 with a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 517591.1714285
If we take 875 away from 1000, we end up 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.

Going ahead to step 16:
1250 divided by 175 is 7 with a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 517591.17142857
If we subtract 1225 from 1250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 517591.17142857 with a remaining 2.5e-08.
