917245 ÷ 4 
The aim is to understand the frequency of 4 in 917245.

On to step 1:
If we divide 9 by 4, we get 2 and a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 8 from 9, we get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 4

Going ahead to step 2:
4 can be fit into 11 2 times, resulting in 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.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 4

Going ahead to step 3:
The number 4 fits into 37 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 229.0
Subtracting 36 from 37 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 4

Step 4:
If we divide 12 by 4, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 2293.0
Deduct 12 from 12 and we're left with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 4

Advancing to step 5:
4 goes into 4 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 22931.0
Deduct 4 from 4 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 4

Advancing to step 6:
4 goes into 5 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 229311.0
If we subtract 4 from 5, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
10 divided by 4 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 229311.2
If we take 8 away from 10, we end up 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.

Moving on to step 8:
20 divided by 4 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 229311.25
If we take 20 away from 20, 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.

Moving on to step 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 229311.25
Subtract 0 from 0 to 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.

Let's proceed to step 10:
4 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 229311.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 229311.25 with a remaining 0.0.
