42820093 divided by 976 
The aim is to understand the frequency of 976 in 42820093.

Let's proceed to step 1:
When dividing 4 by 976, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 976

On to step 2:
42 divided by 976 is 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 976

Step 3:
If we divide 428 by 976, we get 0 and a remainder of 428.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 428, we get 428.
Append the next digit (2) from the dividend to 428 and continue with: 4282 / 976

Moving on to step 4:
4282 divided by 976 is 4 with a remainder of 378.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 3904 from 4282 and we're left with 378.
Append the next digit (0) from the dividend to 378 and continue with: 3780 / 976

Going ahead to step 5:
If we divide 3780 by 976, we get 3 and a remainder of 852.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
If we subtract 2928 from 3780, we get 852.
Bring next digit (0) of the dividend behind the 852 and repeat the process: 8520 / 976

Let's proceed to step 6:
8520 divided by 976 is 8 with a remainder of 712.
Put 8 as the next digit of the answer. 
Result so far: 438.0
If we subtract 7808 from 8520, we get 712.
Fetch the next digit (9) from the dividend, attach it to 712 and continue: 7129 / 976

Going ahead to step 7:
The number 976 fits into 7129 7 times, leaving a remainder of 297.
Use 7 as the next digit of our solution. 
Result so far: 4387.0
The remainder is 297 after subtracting 6832 from 7129.
Grab the next digit (3) from the dividend, add it to 297, then carry on: 2973 / 976

Let's proceed to step 8:
2973 divided by 976 is 3 with a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 43873.0
Subtracting 2928 from 2973 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 9:
976 goes into 450 0 times with a remainder of 450.
Put 0 as the next digit of the answer. 
Result so far: 43873.0
If we take 0 away from 450, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 10:
976 can be fit into 4500 4 times, resulting in a remainder of 596.
Record the quotient 4 as the next digit in the result. 
Result so far: 43873.04
If we subtract 3904 from 4500, we get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Moving on to step 11:
976 goes into 5960 6 times with a remainder of 104.
Write down 6 as next digit of the result. 
Result so far: 43873.046
The remainder is 104 after subtracting 5856 from 5960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 12:
The number 976 fits into 1040 1 times, leaving a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 43873.0461
Subtract 976 from 1040 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 13:
When dividing 640 by 976, we get 0 with a remainder of 640.
The next digit of our result is 0. 
Result so far: 43873.0461
Subtract 0 from 640 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 14:
976 goes into 6400 6 times with a remainder of 544.
Record the quotient 6 as the next digit in the result. 
Result so far: 43873.046106
Subtract 5856 from 6400 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Moving on to step 15:
When dividing 5440 by 976, we get 5 with a remainder of 560.
The number 5 becomes the next digit in our result. 
Result so far: 43873.0461065
Deduct 4880 from 5440 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 16:
When dividing 5600 by 976, we get 5 with a remainder of 720.
The number 5 becomes the next digit in our result. 
Result so far: 43873.04610655
If we take 4880 away from 5600, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

The final result is 43873.04610655 with a remainder of 7.2e-07.
