802366 divided by 804 
The aim is to understand the frequency of 804 in 802366.

Let's proceed to step 1:
8 divided by 804 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 804

Going ahead to step 2:
If we divide 80 by 804, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Take the next digit (2) from the dividend and append it to 80, then repeat: 802 / 804

Going ahead to step 3:
If we divide 802 by 804, we get 0 and a remainder of 802.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 802 and we're left with 802.
Take the next digit (3) from the dividend and append it to 802, then repeat: 8023 / 804

Advancing to step 4:
8023 divided by 804 is 9 with a remainder of 787.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 7236 from 8023, we get 787.
Take the next digit (6) from the dividend and append it to 787, then repeat: 7876 / 804

Going ahead to step 5:
804 goes into 7876 9 times with a remainder of 640.
The next digit of our result is 9. 
Result so far: 99.0
The remainder is 640 after subtracting 7236 from 7876.
Bring next digit (6) of the dividend behind the 640 and repeat the process: 6406 / 804

Let's proceed to step 6:
6406 divided by 804 is 7 with a remainder of 778.
Record the quotient 7 as the next digit in the result. 
Result so far: 997.0
If we subtract 5628 from 6406, we get 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

Going ahead to step 7:
When dividing 7780 by 804, we get 9 with a remainder of 544.
Record the quotient 9 as the next digit in the result. 
Result so far: 997.9
The remainder is 544 after subtracting 7236 from 7780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Advancing to step 8:
804 can be fit into 5440 6 times, resulting in a remainder of 616.
Write down 6 as next digit of the result. 
Result so far: 997.96
Deduct 4824 from 5440 and we're left with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Moving on to step 9:
804 can be fit into 6160 7 times, resulting in a remainder of 532.
The number 7 becomes the next digit in our result. 
Result so far: 997.967
Deduct 5628 from 6160 and we're left with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

On to step 10:
804 goes into 5320 6 times with a remainder of 496.
The number 6 becomes the next digit in our result. 
Result so far: 997.9676
Deduct 4824 from 5320 and we're left with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Moving on to step 11:
If we divide 4960 by 804, we get 6 and a remainder of 136.
The number 6 becomes the next digit in our result. 
Result so far: 997.96766
Subtract 4824 from 4960 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Our division results in 997.96766 with a remaining 0.000136.
