Let's divide 320821 by 17
The aim is to understand the frequency of 17 in 320821.

Moving on to step 1:
3 divided by 17 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 17

Going ahead to step 2:
17 can be fit into 32 1 times, resulting in a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 17 from 32 and we're left with 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 17

Advancing to step 3:
The number 17 fits into 150 8 times, leaving a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 14 after subtracting 136 from 150.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 17

Going ahead to step 4:
148 divided by 17 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 188.0
Subtract 136 from 148 to get 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 17

Step 5:
17 goes into 122 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 1887.0
The remainder is 3 after subtracting 119 from 122.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 17

Going ahead to step 6:
17 can be fit into 31 1 times, resulting in a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 18871.0
If we take 17 away from 31, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
When dividing 140 by 17, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 18871.8
Subtract 136 from 140 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
The number 17 fits into 40 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 18871.82
Deduct 34 from 40 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
If we divide 60 by 17, we get 3 and a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 18871.823
Deduct 51 from 60 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
If we divide 90 by 17, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 18871.8235
Deduct 85 from 90 and we're left 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.

Step 11:
17 can be fit into 50 2 times, resulting in a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 18871.82352
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 12:
17 goes into 160 9 times with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 18871.823529
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.

On to step 13:
If we divide 70 by 17, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 18871.8235294
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 14:
17 goes into 20 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 18871.82352941
Subtracting 17 from 20 leaves us 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.

The final outcome is 18871.82352941, with a leftover of 3e-09.
