We look at the division of 81523665 by 976 
The aim is to understand the frequency of 976 in 81523665.

Moving on to step 1:
If we divide 8 by 976, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 976

Advancing to step 2:
The number 976 fits into 81 0 times, leaving a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Include the next digit (5) from the dividend after 81, then repeat: 815 / 976

Step 3:
976 goes into 815 0 times with a remainder of 815.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 815 to get 815.
Take the next digit (2) from the dividend and append it to 815, then repeat: 8152 / 976

Step 4:
When dividing 8152 by 976, we get 8 with a remainder of 344.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 7808 from 8152 leaves us with 344.
Grab the next digit (3) from the dividend, add it to 344, then carry on: 3443 / 976

Going ahead to step 5:
3443 divided by 976 is 3 with a remainder of 515.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
Deduct 2928 from 3443 and we're left with 515.
Include the next digit (6) from the dividend after 515, then repeat: 5156 / 976

On to step 6:
If we divide 5156 by 976, we get 5 and a remainder of 276.
The number 5 becomes the next digit in our result. 
Result so far: 835.0
The remainder is 276 after subtracting 4880 from 5156.
Include the next digit (6) from the dividend after 276, then repeat: 2766 / 976

Moving on to step 7:
976 goes into 2766 2 times with a remainder of 814.
The number 2 becomes the next digit in our result. 
Result so far: 8352.0
Subtract 1952 from 2766 to get 814.
Append the next digit (5) from the dividend to 814 and continue with: 8145 / 976

Moving on to step 8:
The number 976 fits into 8145 8 times, leaving a remainder of 337.
The next digit of our result is 8. 
Result so far: 83528.0
Subtracting 7808 from 8145 leaves us with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Moving on to step 9:
3370 divided by 976 is 3 with a remainder of 442.
The number 3 becomes the next digit in our result. 
Result so far: 83528.3
Deduct 2928 from 3370 and we're left with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

On to step 10:
976 goes into 4420 4 times with a remainder of 516.
The next digit of our result is 4. 
Result so far: 83528.34
Subtract 3904 from 4420 to get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Advancing to step 11:
When dividing 5160 by 976, we get 5 with a remainder of 280.
Record the quotient 5 as the next digit in the result. 
Result so far: 83528.345
If we subtract 4880 from 5160, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 12:
When dividing 2800 by 976, we get 2 with a remainder of 848.
Record the quotient 2 as the next digit in the result. 
Result so far: 83528.3452
The remainder is 848 after subtracting 1952 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8480, and continue the process.

Let's proceed to step 13:
When dividing 8480 by 976, we get 8 with a remainder of 672.
The number 8 becomes the next digit in our result. 
Result so far: 83528.34528
The remainder is 672 after subtracting 7808 from 8480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

On to step 14:
976 goes into 6720 6 times with a remainder of 864.
The number 6 becomes the next digit in our result. 
Result so far: 83528.345286
Subtracting 5856 from 6720 leaves us with 864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8640, and continue the process.

Advancing to step 15:
976 can be fit into 8640 8 times, resulting in a remainder of 832.
The number 8 becomes the next digit in our result. 
Result so far: 83528.3452868
If we take 7808 away from 8640, we end up with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Going ahead to step 16:
When dividing 8320 by 976, we get 8 with a remainder of 512.
Write down 8 as next digit of the result. 
Result so far: 83528.34528688
Deduct 7808 from 8320 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

The final outcome is 83528.34528688, with a leftover of 5.12e-07.
