We divide 400452 by 4
The aim is to understand the frequency of 4 in 400452.

Going ahead to step 1:
4 divided by 4 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 0 after subtracting 4 from 4.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 4

Step 2:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 0 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 4

Going ahead to step 3:
If we divide 0 by 4, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 100.0
Subtract 0 from 0 to get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 4

Step 4:
The number 4 fits into 4 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1001.0
The remainder is 0 after subtracting 4 from 4.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 4

On to step 5:
5 divided by 4 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 10011.0
If we subtract 4 from 5, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 4

On to step 6:
12 divided by 4 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 100113.0
Deduct 12 from 12 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.

Moving on to step 7:
4 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 100113.0
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.

Let's proceed to step 8:
4 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 100113.0
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 final outcome is 100113.0, with a leftover of 0.0.
