We look at the division of 391301 by 17 
The aim is to understand the frequency of 17 in 391301.

Moving on to step 1:
When dividing 3 by 17, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 17

Moving on to step 2:
17 goes into 39 2 times with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 34 from 39 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 17

Step 3:
If we divide 51 by 17, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we subtract 51 from 51, we get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 17

Moving on to step 4:
3 divided by 17 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 230.0
If we take 0 away from 3, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 17

Let's proceed to step 5:
When dividing 30 by 17, we get 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 2301.0
If we take 17 away from 30, we end up with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 17

Step 6:
When dividing 131 by 17, we get 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 23017.0
If we subtract 119 from 131, 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 7:
120 divided by 17 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 23017.7
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 8:
If we divide 10 by 17, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 23017.7
Subtracting 0 from 10 leaves us 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.

Advancing to step 9:
When dividing 100 by 17, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 23017.705
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.

Going ahead to step 10:
The number 17 fits into 150 8 times, leaving a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 23017.7058
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.

Let's proceed to step 11:
When dividing 140 by 17, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 23017.70588
Subtract 136 from 140 to 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.

The quotient of the division is 23017.70588, and the remainder is 4e-06.
