Let's divide 51000 by 4
The aim is to understand the frequency of 4 in 51000.

On to step 1:
5 divided by 4 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 4 from 5 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 4

Step 2:
If we divide 11 by 4, we get 2 and a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 3 after subtracting 8 from 11.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 4

On to step 3:
4 goes into 30 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 127.0
If we subtract 28 from 30, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 4

Moving on to step 4:
When dividing 20 by 4, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1275.0
The remainder is 0 after subtracting 20 from 20.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 4

Let's proceed to step 5:
If we divide 0 by 4, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12750.0
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.

Moving on to step 6:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12750.0
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.

Step 7:
4 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12750.0
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.

In conclusion, the division gives 12750.0 with a balance of 0.0.
