75866565 ÷ 961 
The aim is to understand the frequency of 961 in 75866565.

Let's proceed to step 1:
961 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 961

Advancing to step 2:
If we divide 75 by 961, we get 0 and a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Append the next digit (8) from the dividend to 75 and continue with: 758 / 961

Going ahead to step 3:
The number 961 fits into 758 0 times, leaving a remainder of 758.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 758 and we're left with 758.
Append the next digit (6) from the dividend to 758 and continue with: 7586 / 961

Advancing to step 4:
961 goes into 7586 7 times with a remainder of 859.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 6727 from 7586, we get 859.
Include the next digit (6) from the dividend after 859, then repeat: 8596 / 961

Moving on to step 5:
961 can be fit into 8596 8 times, resulting in a remainder of 908.
Write down 8 as next digit of the result. 
Result so far: 78.0
If we take 7688 away from 8596, we end up with 908.
Include the next digit (5) from the dividend after 908, then repeat: 9085 / 961

Let's proceed to step 6:
If we divide 9085 by 961, we get 9 and a remainder of 436.
Use 9 as the next digit of our solution. 
Result so far: 789.0
Deduct 8649 from 9085 and we're left with 436.
Bring next digit (6) of the dividend behind the 436 and repeat the process: 4366 / 961

Let's proceed to step 7:
When dividing 4366 by 961, we get 4 with a remainder of 522.
The next digit of our result is 4. 
Result so far: 7894.0
Subtract 3844 from 4366 to get 522.
Fetch the next digit (5) from the dividend, attach it to 522 and continue: 5225 / 961

Going ahead to step 8:
When dividing 5225 by 961, we get 5 with a remainder of 420.
The next digit of our result is 5. 
Result so far: 78945.0
The remainder is 420 after subtracting 4805 from 5225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 9:
4200 divided by 961 is 4 with a remainder of 356.
The number 4 becomes the next digit in our result. 
Result so far: 78945.4
If we take 3844 away from 4200, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 10:
When dividing 3560 by 961, we get 3 with a remainder of 677.
Record the quotient 3 as the next digit in the result. 
Result so far: 78945.43
Subtracting 2883 from 3560 leaves us with 677.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

Going ahead to step 11:
If we divide 6770 by 961, we get 7 and a remainder of 43.
The next digit of our result is 7. 
Result so far: 78945.437
Subtract 6727 from 6770 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 12:
The number 961 fits into 430 0 times, leaving a remainder of 430.
Write down 0 as next digit of the result. 
Result so far: 78945.437
The remainder is 430 after subtracting 0 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

On to step 13:
961 goes into 4300 4 times with a remainder of 456.
The number 4 becomes the next digit in our result. 
Result so far: 78945.43704
If we take 3844 away from 4300, we end up with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Moving on to step 14:
When dividing 4560 by 961, we get 4 with a remainder of 716.
Record the quotient 4 as the next digit in the result. 
Result so far: 78945.437044
The remainder is 716 after subtracting 3844 from 4560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

After the division, we end up with 78945.437044 and a remainder of 7.16e-05.
