371617 ÷ 17 
The aim is to understand the frequency of 17 in 371617.

On to step 1:
3 divided by 17 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 17

On to step 2:
17 goes into 37 2 times with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 3 after subtracting 34 from 37.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 17

Step 3:
17 can be fit into 31 1 times, resulting in a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 17 away from 31, we end up with 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 17

Moving on to step 4:
When dividing 146 by 17, we get 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 218.0
Subtract 136 from 146 to get 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 17

On to step 5:
17 can be fit into 101 5 times, resulting in a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 2185.0
The remainder is 16 after subtracting 85 from 101.
Grab the next digit (7) from the dividend, add it to 16, then carry on: 167 / 17

Going ahead to step 6:
When dividing 167 by 17, we get 9 with a remainder of 14.
The next digit of our result is 9. 
Result so far: 21859.0
Subtract 153 from 167 to 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 7:
The number 17 fits into 140 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 21859.8
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.

Let's proceed to step 8:
The number 17 fits into 40 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 21859.82
The remainder is 6 after subtracting 34 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
If we divide 60 by 17, we get 3 and a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 21859.823
If we take 51 away from 60, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
The number 17 fits into 90 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 21859.8235
The remainder is 5 after subtracting 85 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
The number 17 fits into 50 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 21859.82352
If we take 34 away from 50, we end up 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.

On to step 12:
If we divide 160 by 17, we get 9 and a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 21859.823529
Subtracting 153 from 160 leaves us 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.

Let's proceed to step 13:
When dividing 70 by 17, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 21859.8235294
The remainder is 2 after subtracting 68 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
When dividing 20 by 17, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 21859.82352941
Deduct 17 from 20 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 21859.82352941, with a leftover of 3e-09.
