We're dividing 915093 by 4 
The aim is to understand the frequency of 4 in 915093.

Step 1:
9 divided by 4 is 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 8 from 9 to get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 4

On to step 2:
If we divide 11 by 4, we get 2 and a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Deduct 8 from 11 and we're left with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 4

Advancing to step 3:
The number 4 fits into 35 8 times, leaving a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 228.0
Subtracting 32 from 35 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 4

Let's proceed to step 4:
4 goes into 30 7 times with a remainder of 2.
The next digit of our result is 7. 
Result so far: 2287.0
Deduct 28 from 30 and we're left with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 4

Let's proceed to step 5:
When dividing 29 by 4, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 22877.0
If we take 28 away from 29, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 4

Let's proceed to step 6:
When dividing 13 by 4, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 228773.0
Deduct 12 from 13 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
4 goes into 10 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 228773.2
Deduct 8 from 10 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 228773.25
If we subtract 20 from 20, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 4 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 228773.25
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
0 divided by 4 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 228773.25
If we subtract 0 from 0, we get 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 quotient of the division is 228773.25, and the remainder is 0.0.
