Let's divide 15528 by 63
The aim is to understand the frequency of 63 in 15528.

On to step 1:
63 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 63

Step 2:
If we divide 15 by 63, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 63

Step 3:
The number 63 fits into 155 2 times, leaving a remainder of 29.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 126 from 155 and we're left with 29.
Grab the next digit (2) from the dividend, add it to 29, then carry on: 292 / 63

On to step 4:
If we divide 292 by 63, we get 4 and a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we subtract 252 from 292, we get 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 63

Moving on to step 5:
63 can be fit into 408 6 times, resulting in a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 246.0
Subtract 378 from 408 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 6:
If we divide 300 by 63, we get 4 and a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 246.4
The remainder is 48 after subtracting 252 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 7:
When dividing 480 by 63, we get 7 with a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 246.47
Deduct 441 from 480 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 8:
63 goes into 390 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 246.476
Subtracting 378 from 390 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 9:
120 divided by 63 is 1 with a remainder of 57.
The next digit of our result is 1. 
Result so far: 246.4761
If we subtract 63 from 120, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 10:
The number 63 fits into 570 9 times, leaving a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 246.47619
Subtract 567 from 570 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.

Let's proceed to step 11:
63 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 246.47619
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
300 divided by 63 is 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 246.4761904
Deduct 252 from 300 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
63 goes into 480 7 times with a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 246.47619047
Subtracting 441 from 480 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Our division results in 246.47619047 with a remaining 3.9e-08.
