64389317 ÷ 865 
The aim is to understand the frequency of 865 in 64389317.

Advancing to step 1:
If we divide 6 by 865, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 865

Moving on to step 2:
865 goes into 64 0 times with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Append the next digit (3) from the dividend to 64 and continue with: 643 / 865

On to step 3:
643 divided by 865 is 0 with a remainder of 643.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 643 after subtracting 0 from 643.
Take the next digit (8) from the dividend and append it to 643, then repeat: 6438 / 865

On to step 4:
6438 divided by 865 is 7 with a remainder of 383.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 6055 from 6438, we get 383.
Fetch the next digit (9) from the dividend, attach it to 383 and continue: 3839 / 865

Moving on to step 5:
When dividing 3839 by 865, we get 4 with a remainder of 379.
Use 4 as the next digit of our solution. 
Result so far: 74.0
Subtract 3460 from 3839 to get 379.
Append the next digit (3) from the dividend to 379 and continue with: 3793 / 865

On to step 6:
865 can be fit into 3793 4 times, resulting in a remainder of 333.
Put 4 as the next digit of the answer. 
Result so far: 744.0
The remainder is 333 after subtracting 3460 from 3793.
Take the next digit (1) from the dividend and append it to 333, then repeat: 3331 / 865

Step 7:
865 goes into 3331 3 times with a remainder of 736.
Write down 3 as next digit of the result. 
Result so far: 7443.0
Deduct 2595 from 3331 and we're left with 736.
Take the next digit (7) from the dividend and append it to 736, then repeat: 7367 / 865

Let's proceed to step 8:
When dividing 7367 by 865, we get 8 with a remainder of 447.
Record the quotient 8 as the next digit in the result. 
Result so far: 74438.0
The remainder is 447 after subtracting 6920 from 7367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Moving on to step 9:
865 can be fit into 4470 5 times, resulting in a remainder of 145.
The next digit of our result is 5. 
Result so far: 74438.5
Subtract 4325 from 4470 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 10:
The number 865 fits into 1450 1 times, leaving a remainder of 585.
Record the quotient 1 as the next digit in the result. 
Result so far: 74438.51
Subtract 865 from 1450 to get 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

On to step 11:
The number 865 fits into 5850 6 times, leaving a remainder of 660.
Write down 6 as next digit of the result. 
Result so far: 74438.516
The remainder is 660 after subtracting 5190 from 5850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Going ahead to step 12:
865 goes into 6600 7 times with a remainder of 545.
Put 7 as the next digit of the answer. 
Result so far: 74438.5167
Deduct 6055 from 6600 and we're left with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Step 13:
If we divide 5450 by 865, we get 6 and a remainder of 260.
Write down 6 as next digit of the result. 
Result so far: 74438.51676
Deduct 5190 from 5450 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 14:
The number 865 fits into 2600 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 74438.516763
Deduct 2595 from 2600 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 15:
865 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 74438.516763
The remainder is 50 after subtracting 0 from 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 16:
The number 865 fits into 500 0 times, leaving a remainder of 500.
The next digit of our result is 0. 
Result so far: 74438.516763
Subtracting 0 from 500 leaves us 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.

After the division, we end up with 74438.516763 and a remainder of 5e-07.
