We look at the division of 85071 by 63 
The aim is to understand the frequency of 63 in 85071.

Advancing to step 1:
63 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 63

Advancing to step 2:
When dividing 85 by 63, we get 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 63 from 85, we get 22.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 63

Advancing to step 3:
220 divided by 63 is 3 with a remainder of 31.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 189 from 220 leaves us with 31.
Take the next digit (7) from the dividend and append it to 31, then repeat: 317 / 63

Step 4:
63 can be fit into 317 5 times, resulting in a remainder of 2.
The next digit of our result is 5. 
Result so far: 135.0
Deduct 315 from 317 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 63

Advancing to step 5:
63 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 1350.0
Subtract 0 from 21 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 6:
63 can be fit into 210 3 times, resulting in a remainder of 21.
The next digit of our result is 3. 
Result so far: 1350.3
Deduct 189 from 210 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
63 can be fit into 210 3 times, resulting in a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 1350.33
Deduct 189 from 210 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 1350.33 with a remaining 0.021.
