We're dividing 70917794 by 804 
The aim is to understand the frequency of 804 in 70917794.

Going ahead to step 1:
If we divide 7 by 804, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 804

Advancing to step 2:
The number 804 fits into 70 0 times, leaving a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Take the next digit (9) from the dividend and append it to 70, then repeat: 709 / 804

Advancing to step 3:
709 divided by 804 is 0 with a remainder of 709.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 709 leaves us with 709.
Take the next digit (1) from the dividend and append it to 709, then repeat: 7091 / 804

Going ahead to step 4:
804 goes into 7091 8 times with a remainder of 659.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 6432 from 7091 leaves us with 659.
Grab the next digit (7) from the dividend, add it to 659, then carry on: 6597 / 804

On to step 5:
6597 divided by 804 is 8 with a remainder of 165.
Use 8 as the next digit of our solution. 
Result so far: 88.0
Deduct 6432 from 6597 and we're left with 165.
Append the next digit (7) from the dividend to 165 and continue with: 1657 / 804

Step 6:
804 goes into 1657 2 times with a remainder of 49.
Write down 2 as next digit of the result. 
Result so far: 882.0
Subtract 1608 from 1657 to get 49.
Include the next digit (9) from the dividend after 49, then repeat: 499 / 804

Let's proceed to step 7:
804 can be fit into 499 0 times, resulting in a remainder of 499.
The number 0 becomes the next digit in our result. 
Result so far: 8820.0
If we take 0 away from 499, we end up with 499.
Take the next digit (4) from the dividend and append it to 499, then repeat: 4994 / 804

On to step 8:
When dividing 4994 by 804, we get 6 with a remainder of 170.
Use 6 as the next digit of our solution. 
Result so far: 88206.0
Subtracting 4824 from 4994 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.

Let's proceed to step 9:
If we divide 1700 by 804, we get 2 and a remainder of 92.
Record the quotient 2 as the next digit in the result. 
Result so far: 88206.2
Deduct 1608 from 1700 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 10:
If we divide 920 by 804, we get 1 and a remainder of 116.
The number 1 becomes the next digit in our result. 
Result so far: 88206.21
If we subtract 804 from 920, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 11:
The number 804 fits into 1160 1 times, leaving a remainder of 356.
Put 1 as the next digit of the answer. 
Result so far: 88206.211
Subtract 804 from 1160 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

After the division, we end up with 88206.211 and a remainder of 0.0356.
