We look at the division of 57694339 by 17 
The aim is to understand the frequency of 17 in 57694339.

On to step 1:
17 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 17

Step 2:
When dividing 57 by 17, we get 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 51 from 57 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 17

Step 3:
66 divided by 17 is 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
If we take 51 away from 66, we end up with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 17

Advancing to step 4:
The number 17 fits into 159 9 times, leaving a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 339.0
If we take 153 away from 159, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 17

Let's proceed to step 5:
If we divide 64 by 17, we get 3 and a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 3393.0
If we subtract 51 from 64, we get 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 17

Moving on to step 6:
133 divided by 17 is 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 33937.0
Deduct 119 from 133 and we're left with 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 17

Moving on to step 7:
When dividing 143 by 17, we get 8 with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 339378.0
If we subtract 136 from 143, we get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 17

Step 8:
79 divided by 17 is 4 with a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 3393784.0
Subtract 68 from 79 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
If we divide 110 by 17, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 3393784.6
Deduct 102 from 110 and we're left 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.

Going ahead to step 10:
17 goes into 80 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 3393784.64
Deduct 68 from 80 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
17 goes into 120 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 3393784.647
Deduct 119 from 120 and we're left with 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 12:
10 divided by 17 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 3393784.647
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 13:
If we divide 100 by 17, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 3393784.64705
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.

On to step 14:
When dividing 150 by 17, we get 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 3393784.647058
If we take 136 away from 150, we end up 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 15:
The number 17 fits into 140 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 3393784.6470588
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.

The final outcome is 3393784.6470588, with a leftover of 4e-08.
