We're dividing 78503569 by 804 
The aim is to understand the frequency of 804 in 78503569.

Going ahead to step 1:
When dividing 7 by 804, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 804

Going ahead to step 2:
When dividing 78 by 804, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (5) from the dividend, add it to 78, then carry on: 785 / 804

Going ahead to step 3:
804 goes into 785 0 times with a remainder of 785.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 785 to get 785.
Fetch the next digit (0) from the dividend, attach it to 785 and continue: 7850 / 804

Let's proceed to step 4:
If we divide 7850 by 804, we get 9 and a remainder of 614.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 7236 from 7850 leaves us with 614.
Take the next digit (3) from the dividend and append it to 614, then repeat: 6143 / 804

Going ahead to step 5:
6143 divided by 804 is 7 with a remainder of 515.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
The remainder is 515 after subtracting 5628 from 6143.
Grab the next digit (5) from the dividend, add it to 515, then carry on: 5155 / 804

Step 6:
The number 804 fits into 5155 6 times, leaving a remainder of 331.
Use 6 as the next digit of our solution. 
Result so far: 976.0
Subtract 4824 from 5155 to get 331.
Include the next digit (6) from the dividend after 331, then repeat: 3316 / 804

Advancing to step 7:
804 goes into 3316 4 times with a remainder of 100.
Put 4 as the next digit of the answer. 
Result so far: 9764.0
Subtract 3216 from 3316 to get 100.
Grab the next digit (9) from the dividend, add it to 100, then carry on: 1009 / 804

Moving on to step 8:
1009 divided by 804 is 1 with a remainder of 205.
The number 1 becomes the next digit in our result. 
Result so far: 97641.0
The remainder is 205 after subtracting 804 from 1009.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Advancing to step 9:
2050 divided by 804 is 2 with a remainder of 442.
The number 2 becomes the next digit in our result. 
Result so far: 97641.2
Subtracting 1608 from 2050 leaves us with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Moving on to step 10:
804 can be fit into 4420 5 times, resulting in a remainder of 400.
The next digit of our result is 5. 
Result so far: 97641.25
If we subtract 4020 from 4420, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 11:
The number 804 fits into 4000 4 times, leaving a remainder of 784.
The number 4 becomes the next digit in our result. 
Result so far: 97641.254
If we take 3216 away from 4000, we end up with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Step 12:
7840 divided by 804 is 9 with a remainder of 604.
The number 9 becomes the next digit in our result. 
Result so far: 97641.2549
Subtract 7236 from 7840 to get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Going ahead to step 13:
If we divide 6040 by 804, we get 7 and a remainder of 412.
Put 7 as the next digit of the answer. 
Result so far: 97641.25497
The remainder is 412 after subtracting 5628 from 6040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Advancing to step 14:
804 goes into 4120 5 times with a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 97641.254975
If we subtract 4020 from 4120, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 15:
804 can be fit into 1000 1 times, resulting in a remainder of 196.
The number 1 becomes the next digit in our result. 
Result so far: 97641.2549751
Subtract 804 from 1000 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 16:
If we divide 1960 by 804, we get 2 and a remainder of 352.
Write down 2 as next digit of the result. 
Result so far: 97641.25497512
If we take 1608 away from 1960, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

After the division, we end up with 97641.25497512 and a remainder of 3.52e-07.
