We look at the division of 71472146 by 17 
The aim is to understand the frequency of 17 in 71472146.

Step 1:
If we divide 7 by 17, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 17

Step 2:
When dividing 71 by 17, we get 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 68 from 71 to get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 17

Step 3:
17 goes into 34 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 42.0
If we subtract 34 from 34, we get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 17

Going ahead to step 4:
17 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 420.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 17

On to step 5:
17 goes into 72 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 4204.0
The remainder is 4 after subtracting 68 from 72.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 17

Step 6:
41 divided by 17 is 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 42042.0
Deduct 34 from 41 and we're left with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 17

On to step 7:
17 can be fit into 74 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 420424.0
Subtracting 68 from 74 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 17

On to step 8:
If we divide 66 by 17, we get 3 and a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 4204243.0
The remainder is 15 after subtracting 51 from 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
If we divide 150 by 17, we get 8 and a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 4204243.8
Deduct 136 from 150 and we're left with 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 10:
If we divide 140 by 17, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 4204243.88
If we subtract 136 from 140, 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.

In conclusion, the division gives 4204243.88 with a balance of 0.004.
