We're dividing 76525777 by 904 
The aim is to understand the frequency of 904 in 76525777.

On to step 1:
The number 904 fits into 7 0 times, leaving 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.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 904

On to step 2:
904 can be fit into 76 0 times, resulting in a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Include the next digit (5) from the dividend after 76, then repeat: 765 / 904

Step 3:
765 divided by 904 is 0 with a remainder of 765.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 765 after subtracting 0 from 765.
Take the next digit (2) from the dividend and append it to 765, then repeat: 7652 / 904

Advancing to step 4:
904 goes into 7652 8 times with a remainder of 420.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 7232 from 7652 leaves us with 420.
Append the next digit (5) from the dividend to 420 and continue with: 4205 / 904

Let's proceed to step 5:
904 goes into 4205 4 times with a remainder of 589.
The next digit of our result is 4. 
Result so far: 84.0
The remainder is 589 after subtracting 3616 from 4205.
Include the next digit (7) from the dividend after 589, then repeat: 5897 / 904

On to step 6:
The number 904 fits into 5897 6 times, leaving a remainder of 473.
Use 6 as the next digit of our solution. 
Result so far: 846.0
Deduct 5424 from 5897 and we're left with 473.
Include the next digit (7) from the dividend after 473, then repeat: 4737 / 904

Step 7:
904 goes into 4737 5 times with a remainder of 217.
The number 5 becomes the next digit in our result. 
Result so far: 8465.0
The remainder is 217 after subtracting 4520 from 4737.
Include the next digit (7) from the dividend after 217, then repeat: 2177 / 904

Step 8:
2177 divided by 904 is 2 with a remainder of 369.
Record the quotient 2 as the next digit in the result. 
Result so far: 84652.0
If we take 1808 away from 2177, we end up with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Going ahead to step 9:
904 can be fit into 3690 4 times, resulting in a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 84652.4
Deduct 3616 from 3690 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 10:
The number 904 fits into 740 0 times, leaving a remainder of 740.
The number 0 becomes the next digit in our result. 
Result so far: 84652.4
Subtract 0 from 740 to get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

On to step 11:
904 goes into 7400 8 times with a remainder of 168.
The next digit of our result is 8. 
Result so far: 84652.408
If we subtract 7232 from 7400, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 12:
If we divide 1680 by 904, we get 1 and a remainder of 776.
Write down 1 as next digit of the result. 
Result so far: 84652.4081
Subtracting 904 from 1680 leaves us with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Step 13:
904 can be fit into 7760 8 times, resulting in a remainder of 528.
The next digit of our result is 8. 
Result so far: 84652.40818
The remainder is 528 after subtracting 7232 from 7760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 14:
When dividing 5280 by 904, we get 5 with a remainder of 760.
Write down 5 as next digit of the result. 
Result so far: 84652.408185
If we take 4520 away from 5280, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 15:
If we divide 7600 by 904, we get 8 and a remainder of 368.
Write down 8 as next digit of the result. 
Result so far: 84652.4081858
The remainder is 368 after subtracting 7232 from 7600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 16:
904 can be fit into 3680 4 times, resulting in a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 84652.40818584
If we take 3616 away from 3680, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 84652.40818584, and the remainder is 6.4e-08.
