162040 ÷ 4 
The aim is to understand the frequency of 4 in 162040.

Step 1:
4 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 4

Going ahead to step 2:
4 goes into 16 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 16 from 16 to get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 4

Advancing to step 3:
The number 4 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we take 0 away from 2, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 4

Let's proceed to step 4:
If we divide 20 by 4, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 405.0
If we take 20 away from 20, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 4

On to step 5:
4 divided by 4 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 4051.0
If we subtract 4 from 4, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 4

Moving on to step 6:
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: 40510.0
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.

Moving on to step 7:
0 divided by 4 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 40510.0
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.

Let's proceed to step 8:
If we divide 0 by 4, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 40510.0
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 40510.0 and a remainder of 0.0.
