We're dividing 577955 by 17 
The aim is to understand the frequency of 17 in 577955.

Advancing to step 1:
17 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 17

Advancing to step 2:
57 divided by 17 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 51 from 57 leaves us with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 17

Advancing to step 3:
67 divided by 17 is 3 with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Subtracting 51 from 67 leaves us with 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 17

Let's proceed to step 4:
When dividing 169 by 17, we get 9 with a remainder of 16.
The next digit of our result is 9. 
Result so far: 339.0
If we subtract 153 from 169, we get 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 17

Advancing to step 5:
165 divided by 17 is 9 with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 3399.0
Deduct 153 from 165 and we're left with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 17

On to step 6:
The number 17 fits into 125 7 times, leaving a remainder of 6.
The next digit of our result is 7. 
Result so far: 33997.0
The remainder is 6 after subtracting 119 from 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
60 divided by 17 is 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 33997.3
The remainder is 9 after subtracting 51 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 8:
If we divide 90 by 17, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 33997.35
Subtracting 85 from 90 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
If we divide 50 by 17, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 33997.352
Subtract 34 from 50 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
17 goes into 160 9 times with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 33997.3529
If we take 153 away from 160, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 11:
If we divide 70 by 17, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 33997.35294
Deduct 68 from 70 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
17 goes into 20 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 33997.352941
Subtract 17 from 20 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 13:
If we divide 30 by 17, we get 1 and a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 33997.3529411
Deduct 17 from 30 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 33997.3529411 with a remaining 1.3e-07.
