Let's divide 558623 by 17
The aim is to understand the frequency of 17 in 558623.

Advancing to step 1:
The number 17 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 17

Let's proceed to step 2:
55 divided by 17 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 51 from 55 to get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 17

Going ahead to step 3:
If we divide 48 by 17, we get 2 and a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 32.0
Subtract 34 from 48 to get 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 17

Moving on to step 4:
17 can be fit into 146 8 times, resulting in a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 328.0
The remainder is 10 after subtracting 136 from 146.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 17

Moving on to step 5:
102 divided by 17 is 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 3286.0
If we subtract 102 from 102, we get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 17

Going ahead to step 6:
3 divided by 17 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 32860.0
Deduct 0 from 3 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
The number 17 fits into 30 1 times, leaving a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 32860.1
Subtract 17 from 30 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 8:
130 divided by 17 is 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 32860.17
Deduct 119 from 130 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
When dividing 110 by 17, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 32860.176
The remainder is 8 after subtracting 102 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
When dividing 80 by 17, we get 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 32860.1764
Deduct 68 from 80 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
17 can be fit into 120 7 times, resulting in a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 32860.17647
Subtracting 119 from 120 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
17 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 32860.17647
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
17 goes into 100 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 32860.1764705
If we take 85 away from 100, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 14:
When dividing 150 by 17, we get 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 32860.17647058
The remainder is 14 after subtracting 136 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 32860.17647058, with a leftover of 1.4e-08.
