394591 divided by 17 
The aim is to understand the frequency of 17 in 394591.

On to step 1:
17 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 17

Advancing to step 2:
17 can be fit into 39 2 times, resulting in a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 34 from 39 and we're left with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 17

Step 3:
54 divided by 17 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we subtract 51 from 54, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 17

Going ahead to step 4:
If we divide 35 by 17, we get 2 and a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 232.0
Deduct 34 from 35 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 17

Step 5:
The number 17 fits into 19 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 2321.0
If we subtract 17 from 19, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 17

On to step 6:
17 goes into 21 1 times with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 23211.0
If we subtract 17 from 21, we 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.

Going ahead to step 7:
When dividing 40 by 17, we get 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 23211.2
Subtracting 34 from 40 leaves us 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 8:
If we divide 60 by 17, we get 3 and a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 23211.23
The remainder is 9 after subtracting 51 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
When dividing 90 by 17, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 23211.235
Subtract 85 from 90 to get 5.
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 10:
The number 17 fits into 50 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 23211.2352
The remainder is 16 after subtracting 34 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
17 can be fit into 160 9 times, resulting in a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 23211.23529
If we take 153 away from 160, we end up 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 12:
If we divide 70 by 17, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 23211.235294
The remainder is 2 after subtracting 68 from 70.
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 13:
20 divided by 17 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 23211.2352941
If we take 17 away from 20, we end up 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.

Going ahead to step 14:
17 goes into 30 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 23211.23529411
The remainder is 13 after subtracting 17 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 23211.23529411 with a remaining 1.3e-08.
