70068309 ÷ 804 
The aim is to understand the frequency of 804 in 70068309.

Moving on to step 1:
The number 804 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 804

Advancing to step 2:
When dividing 70 by 804, we get 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Include the next digit (0) from the dividend after 70, then repeat: 700 / 804

Let's proceed to step 3:
700 divided by 804 is 0 with a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 700 after subtracting 0 from 700.
Append the next digit (6) from the dividend to 700 and continue with: 7006 / 804

Let's proceed to step 4:
7006 divided by 804 is 8 with a remainder of 574.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 574 after subtracting 6432 from 7006.
Take the next digit (8) from the dividend and append it to 574, then repeat: 5748 / 804

Let's proceed to step 5:
When dividing 5748 by 804, we get 7 with a remainder of 120.
Write down 7 as next digit of the result. 
Result so far: 87.0
Subtracting 5628 from 5748 leaves us with 120.
Take the next digit (3) from the dividend and append it to 120, then repeat: 1203 / 804

Let's proceed to step 6:
The number 804 fits into 1203 1 times, leaving a remainder of 399.
The number 1 becomes the next digit in our result. 
Result so far: 871.0
Subtracting 804 from 1203 leaves us with 399.
Bring next digit (0) of the dividend behind the 399 and repeat the process: 3990 / 804

Advancing to step 7:
The number 804 fits into 3990 4 times, leaving a remainder of 774.
Use 4 as the next digit of our solution. 
Result so far: 8714.0
If we take 3216 away from 3990, we end up with 774.
Include the next digit (9) from the dividend after 774, then repeat: 7749 / 804

Going ahead to step 8:
804 goes into 7749 9 times with a remainder of 513.
Write down 9 as next digit of the result. 
Result so far: 87149.0
If we take 7236 away from 7749, we end up with 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Step 9:
804 can be fit into 5130 6 times, resulting in a remainder of 306.
The next digit of our result is 6. 
Result so far: 87149.6
If we subtract 4824 from 5130, we get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Let's proceed to step 10:
The number 804 fits into 3060 3 times, leaving a remainder of 648.
Record the quotient 3 as the next digit in the result. 
Result so far: 87149.63
Subtract 2412 from 3060 to get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Let's proceed to step 11:
6480 divided by 804 is 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 87149.638
Subtract 6432 from 6480 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
When dividing 480 by 804, we get 0 with a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 87149.638
Subtract 0 from 480 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 13:
804 can be fit into 4800 5 times, resulting in a remainder of 780.
Put 5 as the next digit of the answer. 
Result so far: 87149.63805
The remainder is 780 after subtracting 4020 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Moving on to step 14:
If we divide 7800 by 804, we get 9 and a remainder of 564.
Record the quotient 9 as the next digit in the result. 
Result so far: 87149.638059
Deduct 7236 from 7800 and we're left with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Moving on to step 15:
When dividing 5640 by 804, we get 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 87149.6380597
The remainder is 12 after subtracting 5628 from 5640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 16:
804 can be fit into 120 0 times, resulting in a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 87149.6380597
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 87149.6380597 and a remainder of 1.2e-07.
