We divide 85035431 by 17
The aim is to understand the frequency of 17 in 85035431.

Advancing to step 1:
17 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 17

On to step 2:
The number 17 fits into 85 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 85 away from 85, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 17

Going ahead to step 3:
If we divide 0 by 17, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 50.0
The remainder is 0 after subtracting 0 from 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 17

Advancing to step 4:
17 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 500.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 17

On to step 5:
17 goes into 35 2 times with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 5002.0
Deduct 34 from 35 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 17

Advancing to step 6:
14 divided by 17 is 0 with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 50020.0
If we take 0 away from 14, we end up with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 17

Let's proceed to step 7:
17 goes into 143 8 times with a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 500208.0
Subtract 136 from 143 to get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 17

Going ahead to step 8:
17 goes into 71 4 times with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 5002084.0
Subtract 68 from 71 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
The number 17 fits into 30 1 times, leaving a remainder of 13.
The next digit of our result is 1. 
Result so far: 5002084.1
The remainder is 13 after subtracting 17 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
17 goes into 130 7 times with a remainder of 11.
The next digit of our result is 7. 
Result so far: 5002084.17
The remainder is 11 after subtracting 119 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 11:
The number 17 fits into 110 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 5002084.176
Subtracting 102 from 110 leaves us 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.

Moving on to step 12:
17 can be fit into 80 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 5002084.1764
Subtracting 68 from 80 leaves us 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.

Going ahead to step 13:
If we divide 120 by 17, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 5002084.17647
Subtracting 119 from 120 leaves us 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.

Advancing to step 14:
When dividing 10 by 17, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 5002084.17647
If we take 0 away from 10, we end up 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 15:
When dividing 100 by 17, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 5002084.1764705
If we subtract 85 from 100, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 16:
17 goes into 150 8 times with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 5002084.17647058
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.

After the division, we end up with 5002084.17647058 and a remainder of 1.4e-08.
