Let's divide 624385 by 17
The aim is to understand the frequency of 17 in 624385.

On to step 1:
17 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 17

Going ahead to step 2:
17 goes into 62 3 times with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 51 from 62, we get 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 17

Going ahead to step 3:
17 can be fit into 114 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Subtract 102 from 114 to get 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 17

Going ahead to step 4:
123 divided by 17 is 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 367.0
Deduct 119 from 123 and we're left with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 17

Step 5:
17 goes into 48 2 times with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 3672.0
Subtract 34 from 48 to get 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 17

Let's proceed to step 6:
17 can be fit into 145 8 times, resulting in a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 36728.0
If we subtract 136 from 145, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
The number 17 fits into 90 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 36728.5
The remainder is 5 after subtracting 85 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
When dividing 50 by 17, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 36728.52
If we subtract 34 from 50, we 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.

Moving on to step 9:
When dividing 160 by 17, we get 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 36728.529
Subtracting 153 from 160 leaves us 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.

Step 10:
17 can be fit into 70 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 36728.5294
Subtracting 68 from 70 leaves us 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.

On to step 11:
When dividing 20 by 17, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 36728.52941
If we subtract 17 from 20, we 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.

Going ahead to step 12:
When dividing 30 by 17, we get 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 36728.529411
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.

The final outcome is 36728.529411, with a leftover of 1.3e-06.
