We're dividing 577911 by 63 
The aim is to understand the frequency of 63 in 577911.

Advancing to step 1:
When dividing 5 by 63, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 63

Going ahead to step 2:
63 can be fit into 57 0 times, resulting in a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Bring next digit (7) of the dividend behind the 57 and repeat the process: 577 / 63

On to step 3:
The number 63 fits into 577 9 times, leaving a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 567 from 577 to get 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 63

Advancing to step 4:
If we divide 109 by 63, we get 1 and a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 91.0
Deduct 63 from 109 and we're left with 46.
Append the next digit (1) from the dividend to 46 and continue with: 461 / 63

Advancing to step 5:
63 can be fit into 461 7 times, resulting in a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 917.0
Deduct 441 from 461 and we're left with 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 63

Step 6:
63 goes into 201 3 times with a remainder of 12.
The next digit of our result is 3. 
Result so far: 9173.0
If we subtract 189 from 201, we get 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 7:
63 can be fit into 120 1 times, resulting in a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 9173.1
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.

Advancing to step 8:
63 can be fit into 570 9 times, resulting in a remainder of 3.
The next digit of our result is 9. 
Result so far: 9173.19
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.

Advancing to step 9:
30 divided by 63 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 9173.19
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
63 can be fit into 300 4 times, resulting in a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 9173.1904
Subtract 252 from 300 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
If we divide 480 by 63, we get 7 and a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 9173.19047
Subtract 441 from 480 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 12:
When dividing 390 by 63, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 9173.190476
If we take 378 away from 390, we end up 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.

Let's proceed to step 13:
If we divide 120 by 63, we get 1 and a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 9173.1904761
Deduct 63 from 120 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 14:
63 can be fit into 570 9 times, resulting in a remainder of 3.
The next digit of our result is 9. 
Result so far: 9173.19047619
Deduct 567 from 570 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 9173.19047619 with a remaining 3e-09.
