We're dividing 551802 by 17 
The aim is to understand the frequency of 17 in 551802.

On to step 1:
The number 17 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 17

Advancing to step 2:
17 can be fit into 55 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 51 from 55, we get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 17

Let's proceed to step 3:
41 divided by 17 is 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 32.0
If we subtract 34 from 41, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 17

Going ahead to step 4:
17 can be fit into 78 4 times, resulting in a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 324.0
If we take 68 away from 78, we end up with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 17

On to step 5:
If we divide 100 by 17, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 3245.0
If we subtract 85 from 100, we get 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 17

Moving on to step 6:
When dividing 152 by 17, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 32458.0
Subtracting 136 from 152 leaves us 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.

Going ahead to step 7:
The number 17 fits into 160 9 times, leaving a remainder of 7.
The next digit of our result is 9. 
Result so far: 32458.9
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 8:
17 can be fit into 70 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 32458.94
If we subtract 68 from 70, we 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.

On to step 9:
If we divide 20 by 17, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 32458.941
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.

Moving on to step 10:
17 can be fit into 30 1 times, resulting in a remainder of 13.
The next digit of our result is 1. 
Result so far: 32458.9411
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 quotient of the division is 32458.9411, and the remainder is 0.00013.
