We divide 78543385 by 804
The aim is to understand the frequency of 804 in 78543385.

Going ahead to step 1:
The number 804 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 804

On to step 2:
If we divide 78 by 804, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (5) from the dividend, attach it to 78 and continue: 785 / 804

Advancing to step 3:
When dividing 785 by 804, we get 0 with a remainder of 785.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 785 leaves us with 785.
Fetch the next digit (4) from the dividend, attach it to 785 and continue: 7854 / 804

On to step 4:
7854 divided by 804 is 9 with a remainder of 618.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 7236 away from 7854, we end up with 618.
Take the next digit (3) from the dividend and append it to 618, then repeat: 6183 / 804

Moving on to step 5:
When dividing 6183 by 804, we get 7 with a remainder of 555.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Subtracting 5628 from 6183 leaves us with 555.
Grab the next digit (3) from the dividend, add it to 555, then carry on: 5553 / 804

Step 6:
804 goes into 5553 6 times with a remainder of 729.
The number 6 becomes the next digit in our result. 
Result so far: 976.0
If we take 4824 away from 5553, we end up with 729.
Bring next digit (8) of the dividend behind the 729 and repeat the process: 7298 / 804

Advancing to step 7:
804 goes into 7298 9 times with a remainder of 62.
The next digit of our result is 9. 
Result so far: 9769.0
Deduct 7236 from 7298 and we're left with 62.
Append the next digit (5) from the dividend to 62 and continue with: 625 / 804

On to step 8:
If we divide 625 by 804, we get 0 and a remainder of 625.
The next digit of our result is 0. 
Result so far: 97690.0
Subtract 0 from 625 to get 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

On to step 9:
If we divide 6250 by 804, we get 7 and a remainder of 622.
Use 7 as the next digit of our solution. 
Result so far: 97690.7
If we subtract 5628 from 6250, we get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Advancing to step 10:
If we divide 6220 by 804, we get 7 and a remainder of 592.
The next digit of our result is 7. 
Result so far: 97690.77
If we subtract 5628 from 6220, we get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

The final result is 97690.77 with a remainder of 0.592.
