We look at the division of 28253606 by 798 
The aim is to understand the frequency of 798 in 28253606.

Advancing to step 1:
If we divide 2 by 798, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 798

On to step 2:
When dividing 28 by 798, we get 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 798

Going ahead to step 3:
282 divided by 798 is 0 with a remainder of 282.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 282 and we're left with 282.
Append the next digit (5) from the dividend to 282 and continue with: 2825 / 798

Moving on to step 4:
798 goes into 2825 3 times with a remainder of 431.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 2394 from 2825 and we're left with 431.
Include the next digit (3) from the dividend after 431, then repeat: 4313 / 798

Moving on to step 5:
The number 798 fits into 4313 5 times, leaving a remainder of 323.
Write down 5 as next digit of the result. 
Result so far: 35.0
The remainder is 323 after subtracting 3990 from 4313.
Bring next digit (6) of the dividend behind the 323 and repeat the process: 3236 / 798

Moving on to step 6:
798 goes into 3236 4 times with a remainder of 44.
The next digit of our result is 4. 
Result so far: 354.0
Deduct 3192 from 3236 and we're left with 44.
Append the next digit (0) from the dividend to 44 and continue with: 440 / 798

Going ahead to step 7:
440 divided by 798 is 0 with a remainder of 440.
Put 0 as the next digit of the answer. 
Result so far: 3540.0
Subtracting 0 from 440 leaves us with 440.
Fetch the next digit (6) from the dividend, attach it to 440 and continue: 4406 / 798

Step 8:
When dividing 4406 by 798, we get 5 with a remainder of 416.
Put 5 as the next digit of the answer. 
Result so far: 35405.0
If we take 3990 away from 4406, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 9:
798 can be fit into 4160 5 times, resulting in a remainder of 170.
The number 5 becomes the next digit in our result. 
Result so far: 35405.5
Subtracting 3990 from 4160 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 10:
1700 divided by 798 is 2 with a remainder of 104.
Record the quotient 2 as the next digit in the result. 
Result so far: 35405.52
The remainder is 104 after subtracting 1596 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 11:
798 can be fit into 1040 1 times, resulting in a remainder of 242.
Use 1 as the next digit of our solution. 
Result so far: 35405.521
The remainder is 242 after subtracting 798 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 12:
798 can be fit into 2420 3 times, resulting in a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 35405.5213
The remainder is 26 after subtracting 2394 from 2420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 13:
When dividing 260 by 798, we get 0 with a remainder of 260.
The number 0 becomes the next digit in our result. 
Result so far: 35405.5213
If we subtract 0 from 260, we get 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:
If we divide 2600 by 798, we get 3 and a remainder of 206.
Write down 3 as next digit of the result. 
Result so far: 35405.521303
The remainder is 206 after subtracting 2394 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

On to step 15:
If we divide 2060 by 798, we get 2 and a remainder of 464.
The number 2 becomes the next digit in our result. 
Result so far: 35405.5213032
If we take 1596 away from 2060, we end up with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 16:
When dividing 4640 by 798, we get 5 with a remainder of 650.
Put 5 as the next digit of the answer. 
Result so far: 35405.52130325
Deduct 3990 from 4640 and we're left with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

The final outcome is 35405.52130325, with a leftover of 6.5e-07.
