Let's divide 80745817 by 965
The aim is to understand the frequency of 965 in 80745817.

Moving on to step 1:
The number 965 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 965

Advancing to step 2:
When dividing 80 by 965, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Bring next digit (7) of the dividend behind the 80 and repeat the process: 807 / 965

Advancing to step 3:
965 can be fit into 807 0 times, resulting in a remainder of 807.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 807, we get 807.
Fetch the next digit (4) from the dividend, attach it to 807 and continue: 8074 / 965

Advancing to step 4:
8074 divided by 965 is 8 with a remainder of 354.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 7720 from 8074 to get 354.
Take the next digit (5) from the dividend and append it to 354, then repeat: 3545 / 965

Moving on to step 5:
If we divide 3545 by 965, we get 3 and a remainder of 650.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
Subtracting 2895 from 3545 leaves us with 650.
Fetch the next digit (8) from the dividend, attach it to 650 and continue: 6508 / 965

Advancing to step 6:
If we divide 6508 by 965, we get 6 and a remainder of 718.
Use 6 as the next digit of our solution. 
Result so far: 836.0
The remainder is 718 after subtracting 5790 from 6508.
Grab the next digit (1) from the dividend, add it to 718, then carry on: 7181 / 965

Moving on to step 7:
The number 965 fits into 7181 7 times, leaving a remainder of 426.
Record the quotient 7 as the next digit in the result. 
Result so far: 8367.0
The remainder is 426 after subtracting 6755 from 7181.
Append the next digit (7) from the dividend to 426 and continue with: 4267 / 965

On to step 8:
965 goes into 4267 4 times with a remainder of 407.
Put 4 as the next digit of the answer. 
Result so far: 83674.0
Deduct 3860 from 4267 and we're left with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Step 9:
If we divide 4070 by 965, we get 4 and a remainder of 210.
The number 4 becomes the next digit in our result. 
Result so far: 83674.4
Subtracting 3860 from 4070 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 10:
2100 divided by 965 is 2 with a remainder of 170.
Put 2 as the next digit of the answer. 
Result so far: 83674.42
Subtracting 1930 from 2100 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 11:
965 can be fit into 1700 1 times, resulting in a remainder of 735.
Put 1 as the next digit of the answer. 
Result so far: 83674.421
Deduct 965 from 1700 and we're left with 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Going ahead to step 12:
The number 965 fits into 7350 7 times, leaving a remainder of 595.
Use 7 as the next digit of our solution. 
Result so far: 83674.4217
Subtract 6755 from 7350 to get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

On to step 13:
If we divide 5950 by 965, we get 6 and a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 83674.42176
Subtract 5790 from 5950 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 14:
The number 965 fits into 1600 1 times, leaving a remainder of 635.
The number 1 becomes the next digit in our result. 
Result so far: 83674.421761
The remainder is 635 after subtracting 965 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Step 15:
965 goes into 6350 6 times with a remainder of 560.
The next digit of our result is 6. 
Result so far: 83674.4217616
The remainder is 560 after subtracting 5790 from 6350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 16:
The number 965 fits into 5600 5 times, leaving a remainder of 775.
Write down 5 as next digit of the result. 
Result so far: 83674.42176165
Subtract 4825 from 5600 to get 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

The final result is 83674.42176165 with a remainder of 7.75e-07.
