We look at the division of 83494582 by 804 
The aim is to understand the frequency of 804 in 83494582.

On to step 1:
The number 804 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 804

Going ahead to step 2:
When dividing 83 by 804, we get 0 with a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Take the next digit (4) from the dividend and append it to 83, then repeat: 834 / 804

Step 3:
If we divide 834 by 804, we get 1 and a remainder of 30.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 804 from 834 and we're left with 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 804

Going ahead to step 4:
If we divide 309 by 804, we get 0 and a remainder of 309.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 309, we end up with 309.
Grab the next digit (4) from the dividend, add it to 309, then carry on: 3094 / 804

Step 5:
3094 divided by 804 is 3 with a remainder of 682.
Use 3 as the next digit of our solution. 
Result so far: 103.0
Subtract 2412 from 3094 to get 682.
Take the next digit (5) from the dividend and append it to 682, then repeat: 6825 / 804

Let's proceed to step 6:
804 goes into 6825 8 times with a remainder of 393.
The next digit of our result is 8. 
Result so far: 1038.0
The remainder is 393 after subtracting 6432 from 6825.
Take the next digit (8) from the dividend and append it to 393, then repeat: 3938 / 804

Going ahead to step 7:
804 goes into 3938 4 times with a remainder of 722.
Write down 4 as next digit of the result. 
Result so far: 10384.0
Subtract 3216 from 3938 to get 722.
Grab the next digit (2) from the dividend, add it to 722, then carry on: 7222 / 804

Step 8:
The number 804 fits into 7222 8 times, leaving a remainder of 790.
Use 8 as the next digit of our solution. 
Result so far: 103848.0
Subtract 6432 from 7222 to get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Step 9:
804 goes into 7900 9 times with a remainder of 664.
Write down 9 as next digit of the result. 
Result so far: 103848.9
Subtract 7236 from 7900 to get 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Moving on to step 10:
804 can be fit into 6640 8 times, resulting in a remainder of 208.
The next digit of our result is 8. 
Result so far: 103848.98
Deduct 6432 from 6640 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 11:
804 goes into 2080 2 times with a remainder of 472.
Put 2 as the next digit of the answer. 
Result so far: 103848.982
Subtract 1608 from 2080 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Moving on to step 12:
804 can be fit into 4720 5 times, resulting in a remainder of 700.
Write down 5 as next digit of the result. 
Result so far: 103848.9825
Subtracting 4020 from 4720 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Advancing to step 13:
804 can be fit into 7000 8 times, resulting in a remainder of 568.
The number 8 becomes the next digit in our result. 
Result so far: 103848.98258
If we subtract 6432 from 7000, we get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Going ahead to step 14:
804 goes into 5680 7 times with a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 103848.982587
If we take 5628 away from 5680, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 15:
When dividing 520 by 804, we get 0 with a remainder of 520.
Record the quotient 0 as the next digit in the result. 
Result so far: 103848.982587
The remainder is 520 after subtracting 0 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 16:
When dividing 5200 by 804, we get 6 with a remainder of 376.
Write down 6 as next digit of the result. 
Result so far: 103848.98258706
Deduct 4824 from 5200 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

After the division, we end up with 103848.98258706 and a remainder of 3.76e-07.
