We look at the division of 38283760 by 877 
The aim is to understand the frequency of 877 in 38283760.

On to step 1:
The number 877 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 877

Let's proceed to step 2:
877 goes into 38 0 times with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Take the next digit (2) from the dividend and append it to 38, then repeat: 382 / 877

On to step 3:
382 divided by 877 is 0 with a remainder of 382.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 382 after subtracting 0 from 382.
Append the next digit (8) from the dividend to 382 and continue with: 3828 / 877

Advancing to step 4:
877 goes into 3828 4 times with a remainder of 320.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 3508 from 3828 and we're left with 320.
Fetch the next digit (3) from the dividend, attach it to 320 and continue: 3203 / 877

Advancing to step 5:
The number 877 fits into 3203 3 times, leaving a remainder of 572.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtracting 2631 from 3203 leaves us with 572.
Take the next digit (7) from the dividend and append it to 572, then repeat: 5727 / 877

On to step 6:
5727 divided by 877 is 6 with a remainder of 465.
Use 6 as the next digit of our solution. 
Result so far: 436.0
The remainder is 465 after subtracting 5262 from 5727.
Take the next digit (6) from the dividend and append it to 465, then repeat: 4656 / 877

Step 7:
The number 877 fits into 4656 5 times, leaving a remainder of 271.
The number 5 becomes the next digit in our result. 
Result so far: 4365.0
The remainder is 271 after subtracting 4385 from 4656.
Take the next digit (0) from the dividend and append it to 271, then repeat: 2710 / 877

Let's proceed to step 8:
877 goes into 2710 3 times with a remainder of 79.
The next digit of our result is 3. 
Result so far: 43653.0
The remainder is 79 after subtracting 2631 from 2710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 9:
877 can be fit into 790 0 times, resulting in a remainder of 790.
Write down 0 as next digit of the result. 
Result so far: 43653.0
Subtract 0 from 790 to get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Let's proceed to step 10:
877 can be fit into 7900 9 times, resulting in a remainder of 7.
The next digit of our result is 9. 
Result so far: 43653.09
If we take 7893 away from 7900, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 11:
877 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 43653.09
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 12:
When dividing 700 by 877, we get 0 with a remainder of 700.
The number 0 becomes the next digit in our result. 
Result so far: 43653.09
Subtract 0 from 700 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The quotient of the division is 43653.09, and the remainder is 0.007.
