381901 divided by 17 
The aim is to understand the frequency of 17 in 381901.

Let's proceed to step 1:
3 divided by 17 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 17

On to step 2:
38 divided by 17 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 34 from 38 leaves us with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 17

Let's proceed to step 3:
17 goes into 41 2 times with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 34 from 41, we get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 17

Let's proceed to step 4:
If we divide 79 by 17, we get 4 and a remainder of 11.
The next digit of our result is 4. 
Result so far: 224.0
The remainder is 11 after subtracting 68 from 79.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 17

Going ahead to step 5:
110 divided by 17 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 2246.0
If we subtract 102 from 110, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 17

Going ahead to step 6:
81 divided by 17 is 4 with a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 22464.0
If we subtract 68 from 81, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
The number 17 fits into 130 7 times, leaving a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 22464.7
If we take 119 away from 130, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 8:
110 divided by 17 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 22464.76
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.

Let's proceed to step 9:
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: 22464.764
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.

Step 10:
120 divided by 17 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 22464.7647
If we take 119 away from 120, we end up 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.

Step 11:
10 divided by 17 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 22464.7647
Deduct 0 from 10 and we're left 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.

Step 12:
100 divided by 17 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 22464.764705
Deduct 85 from 100 and we're left 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.

Moving on to step 13:
150 divided by 17 is 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 22464.7647058
Subtracting 136 from 150 leaves us 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.

Step 14:
The number 17 fits into 140 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 22464.76470588
Deduct 136 from 140 and we're left with 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 22464.76470588, with a leftover of 4e-09.
