We divide 87399903 by 976
The aim is to understand the frequency of 976 in 87399903.

Moving on to step 1:
The number 976 fits into 8 0 times, leaving 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 / 976

Step 2:
If we divide 87 by 976, we get 0 and a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Take the next digit (3) from the dividend and append it to 87, then repeat: 873 / 976

Step 3:
The number 976 fits into 873 0 times, leaving a remainder of 873.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 873 to get 873.
Take the next digit (9) from the dividend and append it to 873, then repeat: 8739 / 976

Moving on to step 4:
8739 divided by 976 is 8 with a remainder of 931.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 7808 from 8739 and we're left with 931.
Fetch the next digit (9) from the dividend, attach it to 931 and continue: 9319 / 976

Going ahead to step 5:
976 can be fit into 9319 9 times, resulting in a remainder of 535.
The next digit of our result is 9. 
Result so far: 89.0
If we subtract 8784 from 9319, we get 535.
Take the next digit (9) from the dividend and append it to 535, then repeat: 5359 / 976

Moving on to step 6:
If we divide 5359 by 976, we get 5 and a remainder of 479.
The next digit of our result is 5. 
Result so far: 895.0
The remainder is 479 after subtracting 4880 from 5359.
Take the next digit (0) from the dividend and append it to 479, then repeat: 4790 / 976

Let's proceed to step 7:
If we divide 4790 by 976, we get 4 and a remainder of 886.
Write down 4 as next digit of the result. 
Result so far: 8954.0
Subtracting 3904 from 4790 leaves us with 886.
Fetch the next digit (3) from the dividend, attach it to 886 and continue: 8863 / 976

Step 8:
976 goes into 8863 9 times with a remainder of 79.
The number 9 becomes the next digit in our result. 
Result so far: 89549.0
Subtract 8784 from 8863 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 9:
790 divided by 976 is 0 with a remainder of 790.
Put 0 as the next digit of the answer. 
Result so far: 89549.0
Deduct 0 from 790 and we're left with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

On to step 10:
If we divide 7900 by 976, we get 8 and a remainder of 92.
The next digit of our result is 8. 
Result so far: 89549.08
If we subtract 7808 from 7900, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 11:
976 goes into 920 0 times with a remainder of 920.
Put 0 as the next digit of the answer. 
Result so far: 89549.08
The remainder is 920 after subtracting 0 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9200, and continue the process.

Step 12:
The number 976 fits into 9200 9 times, leaving a remainder of 416.
Record the quotient 9 as the next digit in the result. 
Result so far: 89549.0809
If we take 8784 away from 9200, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 13:
976 can be fit into 4160 4 times, resulting in a remainder of 256.
The number 4 becomes the next digit in our result. 
Result so far: 89549.08094
If we subtract 3904 from 4160, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 14:
976 goes into 2560 2 times with a remainder of 608.
Write down 2 as next digit of the result. 
Result so far: 89549.080942
Deduct 1952 from 2560 and we're left with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Step 15:
If we divide 6080 by 976, we get 6 and a remainder of 224.
The next digit of our result is 6. 
Result so far: 89549.0809426
If we take 5856 away from 6080, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 16:
976 goes into 2240 2 times with a remainder of 288.
The next digit of our result is 2. 
Result so far: 89549.08094262
Subtracting 1952 from 2240 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final result is 89549.08094262 with a remainder of 2.88e-07.
