We look at the division of 31464884 by 805 
The aim is to understand the frequency of 805 in 31464884.

Going ahead to step 1:
805 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 805

On to step 2:
The number 805 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Grab the next digit (4) from the dividend, add it to 31, then carry on: 314 / 805

Moving on to step 3:
314 divided by 805 is 0 with a remainder of 314.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 314 and we're left with 314.
Include the next digit (6) from the dividend after 314, then repeat: 3146 / 805

Let's proceed to step 4:
805 goes into 3146 3 times with a remainder of 731.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 731 after subtracting 2415 from 3146.
Include the next digit (4) from the dividend after 731, then repeat: 7314 / 805

Going ahead to step 5:
If we divide 7314 by 805, we get 9 and a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtract 7245 from 7314 to get 69.
Include the next digit (8) from the dividend after 69, then repeat: 698 / 805

On to step 6:
The number 805 fits into 698 0 times, leaving a remainder of 698.
The number 0 becomes the next digit in our result. 
Result so far: 390.0
The remainder is 698 after subtracting 0 from 698.
Include the next digit (8) from the dividend after 698, then repeat: 6988 / 805

Moving on to step 7:
If we divide 6988 by 805, we get 8 and a remainder of 548.
The next digit of our result is 8. 
Result so far: 3908.0
Subtracting 6440 from 6988 leaves us with 548.
Take the next digit (4) from the dividend and append it to 548, then repeat: 5484 / 805

Step 8:
If we divide 5484 by 805, we get 6 and a remainder of 654.
Record the quotient 6 as the next digit in the result. 
Result so far: 39086.0
Deduct 4830 from 5484 and we're left with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Going ahead to step 9:
The number 805 fits into 6540 8 times, leaving a remainder of 100.
Record the quotient 8 as the next digit in the result. 
Result so far: 39086.8
The remainder is 100 after subtracting 6440 from 6540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 10:
805 can be fit into 1000 1 times, resulting in a remainder of 195.
Write down 1 as next digit of the result. 
Result so far: 39086.81
The remainder is 195 after subtracting 805 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 11:
805 can be fit into 1950 2 times, resulting in a remainder of 340.
Put 2 as the next digit of the answer. 
Result so far: 39086.812
The remainder is 340 after subtracting 1610 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 12:
When dividing 3400 by 805, we get 4 with a remainder of 180.
The next digit of our result is 4. 
Result so far: 39086.8124
If we take 3220 away from 3400, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 13:
805 goes into 1800 2 times with a remainder of 190.
The number 2 becomes the next digit in our result. 
Result so far: 39086.81242
If we subtract 1610 from 1800, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 14:
1900 divided by 805 is 2 with a remainder of 290.
Record the quotient 2 as the next digit in the result. 
Result so far: 39086.812422
Subtracting 1610 from 1900 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

The final outcome is 39086.812422, with a leftover of 2.9e-05.
