We're dividing 40839454 by 865 
The aim is to understand the frequency of 865 in 40839454.

Let's proceed to step 1:
If we divide 4 by 865, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 865

Going ahead to step 2:
The number 865 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 865

Moving on to step 3:
When dividing 408 by 865, we get 0 with a remainder of 408.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 408 after subtracting 0 from 408.
Append the next digit (3) from the dividend to 408 and continue with: 4083 / 865

Moving on to step 4:
865 goes into 4083 4 times with a remainder of 623.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 3460 away from 4083, we end up with 623.
Append the next digit (9) from the dividend to 623 and continue with: 6239 / 865

Moving on to step 5:
If we divide 6239 by 865, we get 7 and a remainder of 184.
Use 7 as the next digit of our solution. 
Result so far: 47.0
Deduct 6055 from 6239 and we're left with 184.
Include the next digit (4) from the dividend after 184, then repeat: 1844 / 865

On to step 6:
1844 divided by 865 is 2 with a remainder of 114.
Use 2 as the next digit of our solution. 
Result so far: 472.0
The remainder is 114 after subtracting 1730 from 1844.
Grab the next digit (5) from the dividend, add it to 114, then carry on: 1145 / 865

Going ahead to step 7:
When dividing 1145 by 865, we get 1 with a remainder of 280.
Record the quotient 1 as the next digit in the result. 
Result so far: 4721.0
The remainder is 280 after subtracting 865 from 1145.
Fetch the next digit (4) from the dividend, attach it to 280 and continue: 2804 / 865

Let's proceed to step 8:
When dividing 2804 by 865, we get 3 with a remainder of 209.
The number 3 becomes the next digit in our result. 
Result so far: 47213.0
If we take 2595 away from 2804, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Advancing to step 9:
When dividing 2090 by 865, we get 2 with a remainder of 360.
The next digit of our result is 2. 
Result so far: 47213.2
The remainder is 360 after subtracting 1730 from 2090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 10:
865 can be fit into 3600 4 times, resulting in a remainder of 140.
Write down 4 as next digit of the result. 
Result so far: 47213.24
Subtracting 3460 from 3600 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 11:
When dividing 1400 by 865, we get 1 with a remainder of 535.
Use 1 as the next digit of our solution. 
Result so far: 47213.241
Deduct 865 from 1400 and we're left with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

On to step 12:
If we divide 5350 by 865, we get 6 and a remainder of 160.
The number 6 becomes the next digit in our result. 
Result so far: 47213.2416
If we subtract 5190 from 5350, we 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.

Advancing to step 13:
When dividing 1600 by 865, we get 1 with a remainder of 735.
Put 1 as the next digit of the answer. 
Result so far: 47213.24161
If we take 865 away from 1600, we end up 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 14:
The number 865 fits into 7350 8 times, leaving a remainder of 430.
Write down 8 as next digit of the result. 
Result so far: 47213.241618
Subtract 6920 from 7350 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 15:
865 goes into 4300 4 times with a remainder of 840.
The number 4 becomes the next digit in our result. 
Result so far: 47213.2416184
Subtract 3460 from 4300 to get 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Advancing to step 16:
8400 divided by 865 is 9 with a remainder of 615.
Use 9 as the next digit of our solution. 
Result so far: 47213.24161849
The remainder is 615 after subtracting 7785 from 8400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

After the division, we end up with 47213.24161849 and a remainder of 6.15e-07.
