79251 divided by 4 
The aim is to understand the frequency of 4 in 79251.

Moving on to step 1:
7 divided by 4 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 4 from 7, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 4

Let's proceed to step 2:
When dividing 39 by 4, we get 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 36 from 39 leaves us with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 4

Moving on to step 3:
The number 4 fits into 32 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 198.0
If we take 32 away from 32, we end up with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 4

Going ahead to step 4:
When dividing 5 by 4, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1981.0
The remainder is 1 after subtracting 4 from 5.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 4

Going ahead to step 5:
11 divided by 4 is 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 19812.0
If we take 8 away from 11, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 6:
The number 4 fits into 30 7 times, leaving a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 19812.7
The remainder is 2 after subtracting 28 from 30.
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 7:
If we divide 20 by 4, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 19812.75
Subtract 20 from 20 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.

Step 8:
4 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 19812.75
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.

On to step 9:
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: 19812.75
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.

The quotient of the division is 19812.75, and the remainder is 0.0.
