691771 divided by 63 
The aim is to understand the frequency of 63 in 691771.

Let's proceed to step 1:
63 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 63

Step 2:
The number 63 fits into 69 1 times, leaving a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 63 from 69, we get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 63

Advancing to step 3:
61 divided by 63 is 0 with a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 61, we get 61.
Bring next digit (7) of the dividend behind the 61 and repeat the process: 617 / 63

Advancing to step 4:
When dividing 617 by 63, we get 9 with a remainder of 50.
Record the quotient 9 as the next digit in the result. 
Result so far: 109.0
The remainder is 50 after subtracting 567 from 617.
Include the next digit (7) from the dividend after 50, then repeat: 507 / 63

Advancing to step 5:
The number 63 fits into 507 8 times, leaving a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 1098.0
The remainder is 3 after subtracting 504 from 507.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 63

Going ahead to step 6:
63 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 10980.0
Subtracting 0 from 31 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.

Moving on to step 7:
The number 63 fits into 310 4 times, leaving a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 10980.4
Deduct 252 from 310 and we're left 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.

Advancing to step 8:
When dividing 580 by 63, we get 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 10980.49
If we take 567 away from 580, we end up 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.

Let's proceed to step 9:
63 can be fit into 130 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 10980.492
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.

Going ahead to step 10:
If we divide 40 by 63, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 10980.492
Subtracting 0 from 40 leaves us 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.

On to step 11:
The number 63 fits into 400 6 times, leaving a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 10980.49206
Deduct 378 from 400 and we're left 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.

Going ahead to step 12:
If we divide 220 by 63, we get 3 and a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 10980.492063
Subtract 189 from 220 to 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.

Step 13:
63 can be fit into 310 4 times, resulting in a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 10980.4920634
The remainder is 58 after subtracting 252 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 14:
63 can be fit into 580 9 times, resulting in a remainder of 13.
The next digit of our result is 9. 
Result so far: 10980.49206349
If we subtract 567 from 580, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 10980.49206349 with a remainder of 1.3e-08.
