904000 divided by 4 
The aim is to understand the frequency of 4 in 904000.

Moving on to step 1:
9 divided by 4 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 8 away from 9, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 4

Going ahead to step 2:
4 goes into 10 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 8 from 10 to get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 4

Advancing to step 3:
4 goes into 24 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 226.0
If we subtract 24 from 24, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 4

Let's proceed to step 4:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2260.0
The remainder is 0 after subtracting 0 from 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 4

On to step 5:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 22600.0
Subtract 0 from 0 to get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 4

On to step 6:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 226000.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
When dividing 0 by 4, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 226000.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
0 divided by 4 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 226000.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 226000.0, with a leftover of 0.0.
