52545180 divided by 804 
The aim is to understand the frequency of 804 in 52545180.

Step 1:
5 divided by 804 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 804

Moving on to step 2:
804 goes into 52 0 times with a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Bring next digit (5) of the dividend behind the 52 and repeat the process: 525 / 804

Step 3:
When dividing 525 by 804, we get 0 with a remainder of 525.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 525 to get 525.
Include the next digit (4) from the dividend after 525, then repeat: 5254 / 804

Let's proceed to step 4:
804 goes into 5254 6 times with a remainder of 430.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 4824 from 5254, we get 430.
Append the next digit (5) from the dividend to 430 and continue with: 4305 / 804

Going ahead to step 5:
804 can be fit into 4305 5 times, resulting in a remainder of 285.
Write down 5 as next digit of the result. 
Result so far: 65.0
Subtracting 4020 from 4305 leaves us with 285.
Grab the next digit (1) from the dividend, add it to 285, then carry on: 2851 / 804

On to step 6:
The number 804 fits into 2851 3 times, leaving a remainder of 439.
The number 3 becomes the next digit in our result. 
Result so far: 653.0
If we subtract 2412 from 2851, we get 439.
Fetch the next digit (8) from the dividend, attach it to 439 and continue: 4398 / 804

Let's proceed to step 7:
If we divide 4398 by 804, we get 5 and a remainder of 378.
The next digit of our result is 5. 
Result so far: 6535.0
Deduct 4020 from 4398 and we're left with 378.
Fetch the next digit (0) from the dividend, attach it to 378 and continue: 3780 / 804

Moving on to step 8:
804 goes into 3780 4 times with a remainder of 564.
Record the quotient 4 as the next digit in the result. 
Result so far: 65354.0
If we subtract 3216 from 3780, we get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

On to step 9:
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: 65354.7
Subtract 5628 from 5640 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
804 can be fit into 120 0 times, resulting in a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 65354.7
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 11:
When dividing 1200 by 804, we get 1 with a remainder of 396.
Record the quotient 1 as the next digit in the result. 
Result so far: 65354.701
If we take 804 away from 1200, we end up with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 12:
3960 divided by 804 is 4 with a remainder of 744.
Put 4 as the next digit of the answer. 
Result so far: 65354.7014
Deduct 3216 from 3960 and we're left with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Let's proceed to step 13:
If we divide 7440 by 804, we get 9 and a remainder of 204.
Use 9 as the next digit of our solution. 
Result so far: 65354.70149
Subtract 7236 from 7440 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 14:
When dividing 2040 by 804, we get 2 with a remainder of 432.
Record the quotient 2 as the next digit in the result. 
Result so far: 65354.701492
Deduct 1608 from 2040 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 15:
If we divide 4320 by 804, we get 5 and a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 65354.7014925
Subtract 4020 from 4320 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 16:
3000 divided by 804 is 3 with a remainder of 588.
Use 3 as the next digit of our solution. 
Result so far: 65354.70149253
If we take 2412 away from 3000, we end up with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

In conclusion, the division gives 65354.70149253 with a balance of 5.88e-07.
