Let's divide 83940723 by 965
The aim is to understand the frequency of 965 in 83940723.

On to step 1:
965 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 965

On to step 2:
When dividing 83 by 965, we get 0 with a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Bring next digit (9) of the dividend behind the 83 and repeat the process: 839 / 965

Step 3:
965 can be fit into 839 0 times, resulting in a remainder of 839.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 839 after subtracting 0 from 839.
Include the next digit (4) from the dividend after 839, then repeat: 8394 / 965

Going ahead to step 4:
If we divide 8394 by 965, we get 8 and a remainder of 674.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 7720 from 8394 to get 674.
Take the next digit (0) from the dividend and append it to 674, then repeat: 6740 / 965

Step 5:
The number 965 fits into 6740 6 times, leaving a remainder of 950.
Use 6 as the next digit of our solution. 
Result so far: 86.0
Subtracting 5790 from 6740 leaves us with 950.
Include the next digit (7) from the dividend after 950, then repeat: 9507 / 965

Going ahead to step 6:
When dividing 9507 by 965, we get 9 with a remainder of 822.
Record the quotient 9 as the next digit in the result. 
Result so far: 869.0
If we take 8685 away from 9507, we end up with 822.
Fetch the next digit (2) from the dividend, attach it to 822 and continue: 8222 / 965

Going ahead to step 7:
8222 divided by 965 is 8 with a remainder of 502.
Put 8 as the next digit of the answer. 
Result so far: 8698.0
If we subtract 7720 from 8222, we get 502.
Fetch the next digit (3) from the dividend, attach it to 502 and continue: 5023 / 965

Going ahead to step 8:
The number 965 fits into 5023 5 times, leaving a remainder of 198.
Write down 5 as next digit of the result. 
Result so far: 86985.0
If we subtract 4825 from 5023, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 9:
The number 965 fits into 1980 2 times, leaving a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 86985.2
Subtracting 1930 from 1980 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
965 can be fit into 500 0 times, resulting in a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 86985.2
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 11:
If we divide 5000 by 965, we get 5 and a remainder of 175.
The next digit of our result is 5. 
Result so far: 86985.205
The remainder is 175 after subtracting 4825 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 12:
If we divide 1750 by 965, we get 1 and a remainder of 785.
Record the quotient 1 as the next digit in the result. 
Result so far: 86985.2051
Deduct 965 from 1750 and we're left with 785.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7850, and continue the process.

Going ahead to step 13:
The number 965 fits into 7850 8 times, leaving a remainder of 130.
The number 8 becomes the next digit in our result. 
Result so far: 86985.20518
If we take 7720 away from 7850, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 14:
The number 965 fits into 1300 1 times, leaving a remainder of 335.
Put 1 as the next digit of the answer. 
Result so far: 86985.205181
If we subtract 965 from 1300, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Moving on to step 15:
The number 965 fits into 3350 3 times, leaving a remainder of 455.
Write down 3 as next digit of the result. 
Result so far: 86985.2051813
If we subtract 2895 from 3350, we get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

On to step 16:
The number 965 fits into 4550 4 times, leaving a remainder of 690.
The next digit of our result is 4. 
Result so far: 86985.20518134
The remainder is 690 after subtracting 3860 from 4550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

The quotient of the division is 86985.20518134, and the remainder is 6.9e-07.
