We divide 787664 by 63
The aim is to understand the frequency of 63 in 787664.

Let's proceed to step 1:
When dividing 7 by 63, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 63

Moving on to step 2:
63 can be fit into 78 1 times, resulting in a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 15 after subtracting 63 from 78.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 63

Step 3:
157 divided by 63 is 2 with a remainder of 31.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 126 from 157 and we're left with 31.
Bring next digit (6) of the dividend behind the 31 and repeat the process: 316 / 63

Advancing to step 4:
The number 63 fits into 316 5 times, leaving a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
If we take 315 away from 316, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 63

Let's proceed to step 5:
If we divide 16 by 63, we get 0 and a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 1250.0
Subtracting 0 from 16 leaves us with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 63

Let's proceed to step 6:
The number 63 fits into 164 2 times, leaving a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 12502.0
Deduct 126 from 164 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
63 goes into 380 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 12502.6
Deduct 378 from 380 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
When dividing 20 by 63, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 12502.6
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
The number 63 fits into 200 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 12502.603
Deduct 189 from 200 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 10:
63 can be fit into 110 1 times, resulting in a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 12502.6031
If we subtract 63 from 110, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 11:
63 goes into 470 7 times with a remainder of 29.
The next digit of our result is 7. 
Result so far: 12502.60317
Deduct 441 from 470 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 12:
When dividing 290 by 63, we get 4 with a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 12502.603174
Subtracting 252 from 290 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 13:
63 can be fit into 380 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 12502.6031746
Subtracting 378 from 380 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
20 divided by 63 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 12502.6031746
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 12502.6031746, with a leftover of 2e-08.
