21056657 divided by 865 
The aim is to understand the frequency of 865 in 21056657.

Advancing to step 1:
865 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 865

Let's proceed to step 2:
865 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 865

Going ahead to step 3:
865 goes into 210 0 times with a remainder of 210.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 210 to get 210.

Moving on to step 4:
The number 865 fits into 2105 2 times, leaving a remainder of 375.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1730 from 2105 leaves us with 375.
Fetch the next digit (6) from the dividend, attach it to 375 and continue: 3756 / 865

Moving on to step 5:
If we divide 3756 by 865, we get 4 and a remainder of 296.
The next digit of our result is 4. 
Result so far: 24.0
The remainder is 296 after subtracting 3460 from 3756.
Grab the next digit (6) from the dividend, add it to 296, then carry on: 2966 / 865

On to step 6:
865 goes into 2966 3 times with a remainder of 371.
Record the quotient 3 as the next digit in the result. 
Result so far: 243.0
Subtract 2595 from 2966 to get 371.
Fetch the next digit (5) from the dividend, attach it to 371 and continue: 3715 / 865

Moving on to step 7:
If we divide 3715 by 865, we get 4 and a remainder of 255.
The next digit of our result is 4. 
Result so far: 2434.0
If we take 3460 away from 3715, we end up with 255.
Fetch the next digit (7) from the dividend, attach it to 255 and continue: 2557 / 865

Step 8:
When dividing 2557 by 865, we get 2 with a remainder of 827.
Write down 2 as next digit of the result. 
Result so far: 24342.0
Deduct 1730 from 2557 and we're left with 827.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8270, and continue the process.

Let's proceed to step 9:
The number 865 fits into 8270 9 times, leaving a remainder of 485.
Write down 9 as next digit of the result. 
Result so far: 24342.9
If we take 7785 away from 8270, we end up with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Step 10:
If we divide 4850 by 865, we get 5 and a remainder of 525.
The number 5 becomes the next digit in our result. 
Result so far: 24342.95
Subtracting 4325 from 4850 leaves us with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Advancing to step 11:
If we divide 5250 by 865, we get 6 and a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 24342.956
Subtract 5190 from 5250 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
The number 865 fits into 600 0 times, leaving a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 24342.956
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 13:
When dividing 6000 by 865, we get 6 with a remainder of 810.
Write down 6 as next digit of the result. 
Result so far: 24342.95606
If we take 5190 away from 6000, we end up with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Moving on to step 14:
The number 865 fits into 8100 9 times, leaving a remainder of 315.
The next digit of our result is 9. 
Result so far: 24342.956069
If we take 7785 away from 8100, we end up with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

On to step 15:
The number 865 fits into 3150 3 times, leaving a remainder of 555.
Write down 3 as next digit of the result. 
Result so far: 24342.9560693
Subtracting 2595 from 3150 leaves us with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Step 16:
865 goes into 5550 6 times with a remainder of 360.
Record the quotient 6 as the next digit in the result. 
Result so far: 24342.95606936
The remainder is 360 after subtracting 5190 from 5550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The final result is 24342.95606936 with a remainder of 3.6e-07.
