We're dividing 561618 by 17 
The aim is to understand the frequency of 17 in 561618.

Moving on to step 1:
If we divide 5 by 17, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 17

Let's proceed to step 2:
If we divide 56 by 17, we get 3 and a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 51 from 56 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 17

Step 3:
17 can be fit into 51 3 times, resulting in a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we take 51 away from 51, we end up with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 17

Let's proceed to step 4:
17 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 330.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 17

Let's proceed to step 5:
17 can be fit into 61 3 times, resulting in a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3303.0
If we take 51 away from 61, we end up with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 17

Advancing to step 6:
When dividing 108 by 17, we get 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 33036.0
Deduct 102 from 108 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.

On to step 7:
17 can be fit into 60 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 33036.3
If we subtract 51 from 60, 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.

Advancing to step 8:
When dividing 90 by 17, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 33036.35
If we take 85 away from 90, we end up 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 9:
The number 17 fits into 50 2 times, leaving a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 33036.352
Deduct 34 from 50 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
160 divided by 17 is 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 33036.3529
The remainder is 7 after subtracting 153 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 11:
70 divided by 17 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 33036.35294
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.

Step 12:
If we divide 20 by 17, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 33036.352941
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.

Advancing to step 13:
17 can be fit into 30 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 33036.3529411
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.

After the division, we end up with 33036.3529411 and a remainder of 1.3e-07.
