We're dividing 406124 by 63 
The aim is to understand the frequency of 63 in 406124.

Going ahead to step 1:
4 divided by 63 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 63

Going ahead to step 2:
The number 63 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Include the next digit (6) from the dividend after 40, then repeat: 406 / 63

Moving on to step 3:
When dividing 406 by 63, we get 6 with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 378 from 406 and we're left with 28.
Bring next digit (1) of the dividend behind the 28 and repeat the process: 281 / 63

Step 4:
281 divided by 63 is 4 with a remainder of 29.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Deduct 252 from 281 and we're left with 29.
Take the next digit (2) from the dividend and append it to 29, then repeat: 292 / 63

Moving on to step 5:
If we divide 292 by 63, we get 4 and a remainder of 40.
The next digit of our result is 4. 
Result so far: 644.0
Deduct 252 from 292 and we're left with 40.
Take the next digit (4) from the dividend and append it to 40, then repeat: 404 / 63

On to step 6:
404 divided by 63 is 6 with a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 6446.0
If we take 378 away from 404, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
If we divide 260 by 63, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 6446.4
If we take 252 away from 260, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
63 can be fit into 80 1 times, resulting in a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 6446.41
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
63 goes into 170 2 times with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 6446.412
Subtracting 126 from 170 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 10:
When dividing 440 by 63, we get 6 with a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 6446.4126
Subtract 378 from 440 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 11:
620 divided by 63 is 9 with a remainder of 53.
Write down 9 as next digit of the result. 
Result so far: 6446.41269
If we subtract 567 from 620, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 12:
63 goes into 530 8 times with a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 6446.412698
Subtracting 504 from 530 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 13:
63 can be fit into 260 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 6446.4126984
Subtracting 252 from 260 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
80 divided by 63 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 6446.41269841
Deduct 63 from 80 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 6446.41269841, with a leftover of 1.7e-08.
