755406 ÷ 63 
The aim is to understand the frequency of 63 in 755406.

Step 1:
63 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 63

Moving on to step 2:
63 goes into 75 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 12 after subtracting 63 from 75.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 63

Advancing to step 3:
The number 63 fits into 125 1 times, leaving a remainder of 62.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 63 from 125, we get 62.
Include the next digit (4) from the dividend after 62, then repeat: 624 / 63

Let's proceed to step 4:
624 divided by 63 is 9 with a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
Deduct 567 from 624 and we're left with 57.
Include the next digit (0) from the dividend after 57, then repeat: 570 / 63

On to step 5:
If we divide 570 by 63, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 1199.0
Subtract 567 from 570 to get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 63

Step 6:
63 can be fit into 36 0 times, resulting in a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 11990.0
Subtract 0 from 36 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
63 can be fit into 360 5 times, resulting in a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 11990.5
Subtracting 315 from 360 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 8:
63 goes into 450 7 times with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 11990.57
Subtracting 441 from 450 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
63 goes into 90 1 times with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 11990.571
If we subtract 63 from 90, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 10:
63 can be fit into 270 4 times, resulting in a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 11990.5714
If we take 252 away from 270, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 11:
The number 63 fits into 180 2 times, leaving a remainder of 54.
The next digit of our result is 2. 
Result so far: 11990.57142
Subtract 126 from 180 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 12:
When dividing 540 by 63, we get 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 11990.571428
If we subtract 504 from 540, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
63 can be fit into 360 5 times, resulting in a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 11990.5714285
If we subtract 315 from 360, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 14:
The number 63 fits into 450 7 times, leaving a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 11990.57142857
If we take 441 away from 450, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 11990.57142857 with a remainder of 9e-09.
