We're dividing 351480 by 17 
The aim is to understand the frequency of 17 in 351480.

On to step 1:
The number 17 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 17

Going ahead to step 2:
The number 17 fits into 35 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 34 from 35 leaves us with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 17

Moving on to step 3:
When dividing 11 by 17, we get 0 with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
The remainder is 11 after subtracting 0 from 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 17

Going ahead to step 4:
17 goes into 114 6 times with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 206.0
Deduct 102 from 114 and we're left with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 17

Let's proceed to step 5:
17 goes into 128 7 times with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 2067.0
Deduct 119 from 128 and we're left with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 17

Going ahead to step 6:
The number 17 fits into 90 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 20675.0
If we subtract 85 from 90, we 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.

Advancing to step 7:
When dividing 50 by 17, we get 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 20675.2
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.

Going ahead to step 8:
17 goes into 160 9 times with a remainder of 7.
The next digit of our result is 9. 
Result so far: 20675.29
Deduct 153 from 160 and we're left 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.

Moving on to step 9:
The number 17 fits into 70 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 20675.294
Subtract 68 from 70 to 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.

Let's proceed to step 10:
20 divided by 17 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 20675.2941
If we subtract 17 from 20, we 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 11:
17 can be fit into 30 1 times, resulting in a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 20675.29411
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.

In conclusion, the division gives 20675.29411 with a balance of 1.3e-05.
