We look at the division of 87612755 by 883 
The aim is to understand the frequency of 883 in 87612755.

Step 1:
883 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 883

Going ahead to step 2:
If we divide 87 by 883, we get 0 and a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Fetch the next digit (6) from the dividend, attach it to 87 and continue: 876 / 883

Advancing to step 3:
876 divided by 883 is 0 with a remainder of 876.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 876 leaves us with 876.
Take the next digit (1) from the dividend and append it to 876, then repeat: 8761 / 883

Let's proceed to step 4:
The number 883 fits into 8761 9 times, leaving a remainder of 814.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 7947 away from 8761, we end up with 814.
Grab the next digit (2) from the dividend, add it to 814, then carry on: 8142 / 883

Step 5:
When dividing 8142 by 883, we get 9 with a remainder of 195.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
Deduct 7947 from 8142 and we're left with 195.
Append the next digit (7) from the dividend to 195 and continue with: 1957 / 883

Step 6:
If we divide 1957 by 883, we get 2 and a remainder of 191.
The number 2 becomes the next digit in our result. 
Result so far: 992.0
Subtracting 1766 from 1957 leaves us with 191.
Fetch the next digit (5) from the dividend, attach it to 191 and continue: 1915 / 883

On to step 7:
1915 divided by 883 is 2 with a remainder of 149.
Record the quotient 2 as the next digit in the result. 
Result so far: 9922.0
Deduct 1766 from 1915 and we're left with 149.
Fetch the next digit (5) from the dividend, attach it to 149 and continue: 1495 / 883

Advancing to step 8:
883 goes into 1495 1 times with a remainder of 612.
Write down 1 as next digit of the result. 
Result so far: 99221.0
Deduct 883 from 1495 and we're left with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Going ahead to step 9:
883 can be fit into 6120 6 times, resulting in a remainder of 822.
The next digit of our result is 6. 
Result so far: 99221.6
Deduct 5298 from 6120 and we're left with 822.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

Moving on to step 10:
883 goes into 8220 9 times with a remainder of 273.
The next digit of our result is 9. 
Result so far: 99221.69
Subtracting 7947 from 8220 leaves us with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

On to step 11:
When dividing 2730 by 883, we get 3 with a remainder of 81.
Use 3 as the next digit of our solution. 
Result so far: 99221.693
If we take 2649 away from 2730, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 12:
When dividing 810 by 883, we get 0 with a remainder of 810.
The number 0 becomes the next digit in our result. 
Result so far: 99221.693
Subtracting 0 from 810 leaves us with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Moving on to step 13:
883 goes into 8100 9 times with a remainder of 153.
Write down 9 as next digit of the result. 
Result so far: 99221.69309
Subtracting 7947 from 8100 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Advancing to step 14:
If we divide 1530 by 883, we get 1 and a remainder of 647.
Record the quotient 1 as the next digit in the result. 
Result so far: 99221.693091
If we subtract 883 from 1530, we get 647.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

Going ahead to step 15:
6470 divided by 883 is 7 with a remainder of 289.
The number 7 becomes the next digit in our result. 
Result so far: 99221.6930917
If we subtract 6181 from 6470, we get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Moving on to step 16:
2890 divided by 883 is 3 with a remainder of 241.
Record the quotient 3 as the next digit in the result. 
Result so far: 99221.69309173
Subtracting 2649 from 2890 leaves us with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

After the division, we end up with 99221.69309173 and a remainder of 2.41e-07.
