178785 divided by 17 
The aim is to understand the frequency of 17 in 178785.

Moving on to step 1:
17 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 17

On to step 2:
17 can be fit into 17 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 0 after subtracting 17 from 17.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 17

Step 3:
When dividing 8 by 17, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 17

Let's proceed to step 4:
The number 17 fits into 87 5 times, leaving a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 105.0
Deduct 85 from 87 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 17

Moving on to step 5:
28 divided by 17 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1051.0
Subtract 17 from 28 to get 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 17

Advancing to step 6:
The number 17 fits into 115 6 times, leaving a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 10516.0
The remainder is 13 after subtracting 102 from 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
17 goes into 130 7 times with a remainder of 11.
The next digit of our result is 7. 
Result so far: 10516.7
Deduct 119 from 130 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 8:
17 goes into 110 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 10516.76
Subtracting 102 from 110 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
80 divided by 17 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 10516.764
If we subtract 68 from 80, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
The number 17 fits into 120 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 10516.7647
If we subtract 119 from 120, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
10 divided by 17 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 10516.7647
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
The number 17 fits into 100 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 10516.764705
Subtracting 85 from 100 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 13:
150 divided by 17 is 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 10516.7647058
Subtract 136 from 150 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 14:
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: 10516.76470588
Deduct 136 from 140 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 10516.76470588 and a remainder of 4e-09.
