Let's divide 36661 by 17
The aim is to understand the frequency of 17 in 36661.

Moving on to step 1:
17 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 17

Moving on to step 2:
If we divide 36 by 17, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 34 from 36 and we're left with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 17

Moving on to step 3:
When dividing 26 by 17, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtract 17 from 26 to get 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 17

On to step 4:
17 goes into 96 5 times with a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 215.0
If we take 85 away from 96, we end up with 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 17

Advancing to step 5:
17 goes into 111 6 times with a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 2156.0
If we subtract 102 from 111, 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.

Step 6:
If we divide 90 by 17, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 2156.5
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.

Moving on to step 7:
50 divided by 17 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 2156.52
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.

Going ahead to step 8:
17 goes into 160 9 times with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 2156.529
Deduct 153 from 160 and we're left 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.

Let's proceed to step 9:
17 can be fit into 70 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 2156.5294
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.

Let's proceed to step 10:
17 can be fit into 20 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 2156.52941
Deduct 17 from 20 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.

Moving on to step 11:
The number 17 fits into 30 1 times, leaving a remainder of 13.
The next digit of our result is 1. 
Result so far: 2156.529411
If we take 17 away from 30, we end up 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 2156.529411, with a leftover of 1.3e-06.
