85407043 ÷ 17 
The aim is to understand the frequency of 17 in 85407043.

Moving on to step 1:
When dividing 8 by 17, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 17

Step 2:
17 goes into 85 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 85 from 85 and we're left with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 17

Moving on to step 3:
If we divide 4 by 17, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 50.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 17

Step 4:
When dividing 40 by 17, we get 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 502.0
If we subtract 34 from 40, we get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 17

Going ahead to step 5:
The number 17 fits into 67 3 times, leaving a remainder of 16.
The next digit of our result is 3. 
Result so far: 5023.0
If we take 51 away from 67, we end up with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 17

Advancing to step 6:
If we divide 160 by 17, we get 9 and a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 50239.0
The remainder is 7 after subtracting 153 from 160.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 17

Moving on to step 7:
If we divide 74 by 17, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 502394.0
If we subtract 68 from 74, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 17

Advancing to step 8:
If we divide 63 by 17, we get 3 and a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 5023943.0
Subtract 51 from 63 to get 12.
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 9:
When dividing 120 by 17, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 5023943.7
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.

Advancing to step 10:
17 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 5023943.7
If we subtract 0 from 10, we 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.

On to step 11:
17 goes into 100 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 5023943.705
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.

Moving on to step 12:
If we divide 150 by 17, we get 8 and a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 5023943.7058
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.

On to step 13:
When dividing 140 by 17, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 5023943.70588
If we take 136 away from 140, we end up 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 result is 5023943.70588 with a remainder of 4e-06.
