Let's divide 279191 by 4
The aim is to understand the frequency of 4 in 279191.

Moving on to step 1:
2 divided by 4 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 4

On to step 2:
27 divided by 4 is 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 24 away from 27, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 4

Step 3:
When dividing 39 by 4, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
The remainder is 3 after subtracting 36 from 39.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 4

Going ahead to step 4:
The number 4 fits into 31 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 697.0
Deduct 28 from 31 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 4

Step 5:
4 can be fit into 39 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 6979.0
Subtract 36 from 39 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 4

Advancing to step 6:
When dividing 31 by 4, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 69797.0
Deduct 28 from 31 and we're left 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 7:
The number 4 fits into 30 7 times, leaving a remainder of 2.
The next digit of our result is 7. 
Result so far: 69797.7
Subtract 28 from 30 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
4 goes into 20 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 69797.75
Subtracting 20 from 20 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.

On to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 69797.75
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.

On to step 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 69797.75
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 69797.75, with a leftover of 0.0.
