We look at the division of 43278830 by 805 
The aim is to understand the frequency of 805 in 43278830.

Advancing to step 1:
805 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 805

On to step 2:
When dividing 43 by 805, we get 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Include the next digit (2) from the dividend after 43, then repeat: 432 / 805

Moving on to step 3:
432 divided by 805 is 0 with a remainder of 432.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 432 leaves us with 432.
Include the next digit (7) from the dividend after 432, then repeat: 4327 / 805

Step 4:
805 goes into 4327 5 times with a remainder of 302.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 4025 away from 4327, we end up with 302.
Take the next digit (8) from the dividend and append it to 302, then repeat: 3028 / 805

Moving on to step 5:
3028 divided by 805 is 3 with a remainder of 613.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
The remainder is 613 after subtracting 2415 from 3028.
Take the next digit (8) from the dividend and append it to 613, then repeat: 6138 / 805

On to step 6:
If we divide 6138 by 805, we get 7 and a remainder of 503.
Use 7 as the next digit of our solution. 
Result so far: 537.0
Subtract 5635 from 6138 to get 503.
Grab the next digit (3) from the dividend, add it to 503, then carry on: 5033 / 805

Let's proceed to step 7:
5033 divided by 805 is 6 with a remainder of 203.
Use 6 as the next digit of our solution. 
Result so far: 5376.0
The remainder is 203 after subtracting 4830 from 5033.
Grab the next digit (0) from the dividend, add it to 203, then carry on: 2030 / 805

Advancing to step 8:
805 goes into 2030 2 times with a remainder of 420.
The number 2 becomes the next digit in our result. 
Result so far: 53762.0
Deduct 1610 from 2030 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 9:
4200 divided by 805 is 5 with a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 53762.5
Subtract 4025 from 4200 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 10:
805 can be fit into 1750 2 times, resulting in a remainder of 140.
The number 2 becomes the next digit in our result. 
Result so far: 53762.52
If we take 1610 away from 1750, we end up 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.

Let's proceed to step 11:
805 goes into 1400 1 times with a remainder of 595.
The next digit of our result is 1. 
Result so far: 53762.521
If we subtract 805 from 1400, we 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.

Going ahead to step 12:
If we divide 5950 by 805, we get 7 and a remainder of 315.
Write down 7 as next digit of the result. 
Result so far: 53762.5217
If we subtract 5635 from 5950, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Let's proceed to step 13:
805 goes into 3150 3 times with a remainder of 735.
The next digit of our result is 3. 
Result so far: 53762.52173
The remainder is 735 after subtracting 2415 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Step 14:
If we divide 7350 by 805, we get 9 and a remainder of 105.
Record the quotient 9 as the next digit in the result. 
Result so far: 53762.521739
The remainder is 105 after subtracting 7245 from 7350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 15:
805 can be fit into 1050 1 times, resulting in a remainder of 245.
The next digit of our result is 1. 
Result so far: 53762.5217391
Deduct 805 from 1050 and we're left with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 16:
When dividing 2450 by 805, we get 3 with a remainder of 35.
The next digit of our result is 3. 
Result so far: 53762.52173913
The remainder is 35 after subtracting 2415 from 2450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 53762.52173913, and the remainder is 3.5e-08.
