587263 ÷ 63 
The aim is to understand the frequency of 63 in 587263.

Step 1:
When dividing 5 by 63, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 63

On to step 2:
If we divide 58 by 63, we get 0 and a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 58 to get 58.
Take the next digit (7) from the dividend and append it to 58, then repeat: 587 / 63

Advancing to step 3:
When dividing 587 by 63, we get 9 with a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 567 from 587 leaves us with 20.
Fetch the next digit (2) from the dividend, attach it to 20 and continue: 202 / 63

Going ahead to step 4:
When dividing 202 by 63, we get 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 93.0
If we take 189 away from 202, we end up with 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 63

Going ahead to step 5:
63 goes into 136 2 times with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 932.0
Subtracting 126 from 136 leaves us with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 63

Step 6:
The number 63 fits into 103 1 times, leaving a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 9321.0
If we take 63 away from 103, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
When dividing 400 by 63, we get 6 with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 9321.6
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
The number 63 fits into 220 3 times, leaving a remainder of 31.
The next digit of our result is 3. 
Result so far: 9321.63
Subtracting 189 from 220 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 9:
If we divide 310 by 63, we get 4 and a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 9321.634
Subtracting 252 from 310 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 10:
The number 63 fits into 580 9 times, leaving a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 9321.6349
Deduct 567 from 580 and we're left with 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 11:
If we divide 130 by 63, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 9321.63492
Subtract 126 from 130 to 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.

Step 12:
If we divide 40 by 63, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 9321.63492
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
63 can be fit into 400 6 times, resulting in a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 9321.6349206
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
When dividing 220 by 63, we get 3 with a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 9321.63492063
If we subtract 189 from 220, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final outcome is 9321.63492063, with a leftover of 3.1e-08.
