Let's divide 642469 by 17
The aim is to understand the frequency of 17 in 642469.

Step 1:
17 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 17

Moving on to step 2:
The number 17 fits into 64 3 times, leaving a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 51 from 64, we get 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 17

Going ahead to step 3:
If we divide 132 by 17, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 37.0
If we subtract 119 from 132, we get 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 17

Going ahead to step 4:
17 goes into 134 7 times with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 377.0
The remainder is 15 after subtracting 119 from 134.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 17

Advancing to step 5:
The number 17 fits into 156 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 3779.0
If we subtract 153 from 156, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 17

Step 6:
When dividing 39 by 17, we get 2 with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 37792.0
Subtracting 34 from 39 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.

On to step 7:
17 goes into 50 2 times with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 37792.2
The remainder is 16 after subtracting 34 from 50.
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 8:
160 divided by 17 is 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 37792.29
If we subtract 153 from 160, we get 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 9:
When dividing 70 by 17, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 37792.294
Subtract 68 from 70 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
The number 17 fits into 20 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 37792.2941
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.

Going ahead to step 11:
If we divide 30 by 17, we get 1 and a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 37792.29411
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.

The final outcome is 37792.29411, with a leftover of 1.3e-05.
