We look at the division of 53243367 by 804 
The aim is to understand the frequency of 804 in 53243367.

Moving on to step 1:
804 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 804

On to step 2:
When dividing 53 by 804, we get 0 with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Fetch the next digit (2) from the dividend, attach it to 53 and continue: 532 / 804

Moving on to step 3:
804 can be fit into 532 0 times, resulting in a remainder of 532.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 532 and we're left with 532.
Fetch the next digit (4) from the dividend, attach it to 532 and continue: 5324 / 804

Moving on to step 4:
804 goes into 5324 6 times with a remainder of 500.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 4824 from 5324 leaves us with 500.
Fetch the next digit (3) from the dividend, attach it to 500 and continue: 5003 / 804

Advancing to step 5:
If we divide 5003 by 804, we get 6 and a remainder of 179.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
If we subtract 4824 from 5003, we get 179.
Include the next digit (3) from the dividend after 179, then repeat: 1793 / 804

On to step 6:
804 can be fit into 1793 2 times, resulting in a remainder of 185.
Use 2 as the next digit of our solution. 
Result so far: 662.0
Subtracting 1608 from 1793 leaves us with 185.
Append the next digit (6) from the dividend to 185 and continue with: 1856 / 804

On to step 7:
If we divide 1856 by 804, we get 2 and a remainder of 248.
The number 2 becomes the next digit in our result. 
Result so far: 6622.0
The remainder is 248 after subtracting 1608 from 1856.
Include the next digit (7) from the dividend after 248, then repeat: 2487 / 804

Going ahead to step 8:
If we divide 2487 by 804, we get 3 and a remainder of 75.
The number 3 becomes the next digit in our result. 
Result so far: 66223.0
Deduct 2412 from 2487 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
804 can be fit into 750 0 times, resulting in a remainder of 750.
Write down 0 as next digit of the result. 
Result so far: 66223.0
Subtracting 0 from 750 leaves us with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Step 10:
804 can be fit into 7500 9 times, resulting in a remainder of 264.
Write down 9 as next digit of the result. 
Result so far: 66223.09
If we subtract 7236 from 7500, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 11:
When dividing 2640 by 804, we get 3 with a remainder of 228.
Write down 3 as next digit of the result. 
Result so far: 66223.093
Subtracting 2412 from 2640 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 12:
When dividing 2280 by 804, we get 2 with a remainder of 672.
Put 2 as the next digit of the answer. 
Result so far: 66223.0932
If we take 1608 away from 2280, we end up with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Moving on to step 13:
804 can be fit into 6720 8 times, resulting in a remainder of 288.
The next digit of our result is 8. 
Result so far: 66223.09328
Deduct 6432 from 6720 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 14:
804 can be fit into 2880 3 times, resulting in a remainder of 468.
The next digit of our result is 3. 
Result so far: 66223.093283
Deduct 2412 from 2880 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Going ahead to step 15:
804 can be fit into 4680 5 times, resulting in a remainder of 660.
Record the quotient 5 as the next digit in the result. 
Result so far: 66223.0932835
If we take 4020 away from 4680, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

On to step 16:
If we divide 6600 by 804, we get 8 and a remainder of 168.
Write down 8 as next digit of the result. 
Result so far: 66223.09328358
The remainder is 168 after subtracting 6432 from 6600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The quotient of the division is 66223.09328358, and the remainder is 1.68e-07.
