We look at the division of 79906891 by 965 
The aim is to understand the frequency of 965 in 79906891.

Moving on to step 1:
7 divided by 965 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 965

Moving on to step 2:
965 goes into 79 0 times with a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Include the next digit (9) from the dividend after 79, then repeat: 799 / 965

Going ahead to step 3:
When dividing 799 by 965, we get 0 with a remainder of 799.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 799 and we're left with 799.
Bring next digit (0) of the dividend behind the 799 and repeat the process: 7990 / 965

Going ahead to step 4:
965 can be fit into 7990 8 times, resulting in a remainder of 270.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 7720 from 7990, we get 270.
Bring next digit (6) of the dividend behind the 270 and repeat the process: 2706 / 965

Let's proceed to step 5:
When dividing 2706 by 965, we get 2 with a remainder of 776.
Put 2 as the next digit of the answer. 
Result so far: 82.0
The remainder is 776 after subtracting 1930 from 2706.
Take the next digit (8) from the dividend and append it to 776, then repeat: 7768 / 965

Let's proceed to step 6:
965 can be fit into 7768 8 times, resulting in a remainder of 48.
The next digit of our result is 8. 
Result so far: 828.0
If we subtract 7720 from 7768, we get 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 965

On to step 7:
965 goes into 489 0 times with a remainder of 489.
Put 0 as the next digit of the answer. 
Result so far: 8280.0
If we take 0 away from 489, we end up with 489.
Bring next digit (1) of the dividend behind the 489 and repeat the process: 4891 / 965

Going ahead to step 8:
965 can be fit into 4891 5 times, resulting in a remainder of 66.
Put 5 as the next digit of the answer. 
Result so far: 82805.0
Deduct 4825 from 4891 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 9:
The number 965 fits into 660 0 times, leaving a remainder of 660.
The next digit of our result is 0. 
Result so far: 82805.0
If we subtract 0 from 660, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 10:
The number 965 fits into 6600 6 times, leaving a remainder of 810.
The number 6 becomes the next digit in our result. 
Result so far: 82805.06
Subtract 5790 from 6600 to get 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Step 11:
965 goes into 8100 8 times with a remainder of 380.
Use 8 as the next digit of our solution. 
Result so far: 82805.068
If we take 7720 away from 8100, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 12:
965 can be fit into 3800 3 times, resulting in a remainder of 905.
Put 3 as the next digit of the answer. 
Result so far: 82805.0683
Deduct 2895 from 3800 and we're left with 905.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9050, and continue the process.

Let's proceed to step 13:
9050 divided by 965 is 9 with a remainder of 365.
Write down 9 as next digit of the result. 
Result so far: 82805.06839
Subtract 8685 from 9050 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 14:
When dividing 3650 by 965, we get 3 with a remainder of 755.
Write down 3 as next digit of the result. 
Result so far: 82805.068393
If we subtract 2895 from 3650, we get 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Let's proceed to step 15:
965 can be fit into 7550 7 times, resulting in a remainder of 795.
Write down 7 as next digit of the result. 
Result so far: 82805.0683937
Subtract 6755 from 7550 to get 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

Step 16:
The number 965 fits into 7950 8 times, leaving a remainder of 230.
Record the quotient 8 as the next digit in the result. 
Result so far: 82805.06839378
The remainder is 230 after subtracting 7720 from 7950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

The final outcome is 82805.06839378, with a leftover of 2.3e-07.
