98948044 ÷ 904 
The aim is to understand the frequency of 904 in 98948044.

Step 1:
904 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 904

On to step 2:
904 goes into 98 0 times with a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 98, we end up with 98.
Grab the next digit (9) from the dividend, add it to 98, then carry on: 989 / 904

Going ahead to step 3:
The number 904 fits into 989 1 times, leaving a remainder of 85.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 904 from 989, we get 85.
Take the next digit (4) from the dividend and append it to 85, then repeat: 854 / 904

Let's proceed to step 4:
854 divided by 904 is 0 with a remainder of 854.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 854 after subtracting 0 from 854.
Include the next digit (8) from the dividend after 854, then repeat: 8548 / 904

Going ahead to step 5:
8548 divided by 904 is 9 with a remainder of 412.
Put 9 as the next digit of the answer. 
Result so far: 109.0
The remainder is 412 after subtracting 8136 from 8548.
Grab the next digit (0) from the dividend, add it to 412, then carry on: 4120 / 904

On to step 6:
When dividing 4120 by 904, we get 4 with a remainder of 504.
Record the quotient 4 as the next digit in the result. 
Result so far: 1094.0
If we subtract 3616 from 4120, we get 504.
Append the next digit (4) from the dividend to 504 and continue with: 5044 / 904

On to step 7:
904 can be fit into 5044 5 times, resulting in a remainder of 524.
The next digit of our result is 5. 
Result so far: 10945.0
If we subtract 4520 from 5044, we get 524.
Bring next digit (4) of the dividend behind the 524 and repeat the process: 5244 / 904

Step 8:
904 goes into 5244 5 times with a remainder of 724.
Record the quotient 5 as the next digit in the result. 
Result so far: 109455.0
If we subtract 4520 from 5244, we get 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

On to step 9:
904 goes into 7240 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 109455.8
If we take 7232 away from 7240, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
When dividing 80 by 904, we get 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 109455.8
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
800 divided by 904 is 0 with a remainder of 800.
Use 0 as the next digit of our solution. 
Result so far: 109455.8
If we take 0 away from 800, we end up with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The final result is 109455.8 with a remainder of 0.08.
