We look at the division of 8449629 by 787 
The aim is to understand the frequency of 787 in 8449629.

Going ahead to step 1:
8 divided by 787 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 787

Step 2:
When dividing 84 by 787, we get 0 with a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Append the next digit (4) from the dividend to 84 and continue with: 844 / 787

Moving on to step 3:
The number 787 fits into 844 1 times, leaving a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 787 from 844 to get 57.
Fetch the next digit (9) from the dividend, attach it to 57 and continue: 579 / 787

Going ahead to step 4:
787 goes into 579 0 times with a remainder of 579.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 579 leaves us with 579.
Append the next digit (6) from the dividend to 579 and continue with: 5796 / 787

Advancing to step 5:
787 goes into 5796 7 times with a remainder of 287.
Write down 7 as next digit of the result. 
Result so far: 107.0
If we subtract 5509 from 5796, we get 287.
Take the next digit (2) from the dividend and append it to 287, then repeat: 2872 / 787

Moving on to step 6:
When dividing 2872 by 787, we get 3 with a remainder of 511.
Write down 3 as next digit of the result. 
Result so far: 1073.0
If we subtract 2361 from 2872, we get 511.
Include the next digit (9) from the dividend after 511, then repeat: 5119 / 787

Moving on to step 7:
The number 787 fits into 5119 6 times, leaving a remainder of 397.
The number 6 becomes the next digit in our result. 
Result so far: 10736.0
Subtracting 4722 from 5119 leaves us with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Going ahead to step 8:
3970 divided by 787 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 10736.5
If we take 3935 away from 3970, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
If we divide 350 by 787, we get 0 and a remainder of 350.
Record the quotient 0 as the next digit in the result. 
Result so far: 10736.5
The remainder is 350 after subtracting 0 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 10:
When dividing 3500 by 787, we get 4 with a remainder of 352.
The number 4 becomes the next digit in our result. 
Result so far: 10736.504
Subtracting 3148 from 3500 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 11:
The number 787 fits into 3520 4 times, leaving a remainder of 372.
Record the quotient 4 as the next digit in the result. 
Result so far: 10736.5044
The remainder is 372 after subtracting 3148 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Our division results in 10736.5044 with a remaining 0.00372.
