We're dividing 615408 by 17 
The aim is to understand the frequency of 17 in 615408.

Advancing to step 1:
17 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 17

Going ahead to step 2:
If we divide 61 by 17, we get 3 and a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 10 after subtracting 51 from 61.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 17

Advancing to step 3:
The number 17 fits into 105 6 times, leaving a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 36.0
If we subtract 102 from 105, we get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 17

On to step 4:
34 divided by 17 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 362.0
If we subtract 34 from 34, we get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 17

Moving on to step 5:
The number 17 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3620.0
Subtract 0 from 0 to get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 17

Let's proceed to step 6:
When dividing 8 by 17, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 36200.0
If we take 0 away from 8, we end up 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.

Advancing to step 7:
When dividing 80 by 17, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 36200.4
The remainder is 12 after subtracting 68 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
17 can be fit into 120 7 times, resulting in a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 36200.47
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.

On to step 9:
10 divided by 17 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 36200.47
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
The number 17 fits into 100 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 36200.4705
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 11:
If we divide 150 by 17, we get 8 and a remainder of 14.
The next digit of our result is 8. 
Result so far: 36200.47058
If we subtract 136 from 150, we 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 12:
The number 17 fits into 140 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 36200.470588
The remainder is 4 after subtracting 136 from 140.
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 36200.470588 and a remainder of 4e-07.
