141873 divided by 4 
The aim is to understand the frequency of 4 in 141873.

Moving on to step 1:
4 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 4

Going ahead to step 2:
14 divided by 4 is 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 12 from 14, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 4

Let's proceed to step 3:
4 goes into 21 5 times with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Subtract 20 from 21 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 4

Going ahead to step 4:
4 goes into 18 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 354.0
Deduct 16 from 18 and we're left with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 4

Going ahead to step 5:
4 goes into 27 6 times with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 3546.0
If we subtract 24 from 27, we get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 4

Let's proceed to step 6:
33 divided by 4 is 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 35468.0
Subtract 32 from 33 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
The number 4 fits into 10 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 35468.2
Subtract 8 from 10 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.

Going ahead to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 35468.25
The remainder is 0 after subtracting 20 from 20.
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.
The next digit of our result is 0. 
Result so far: 35468.25
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 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 35468.25
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 final outcome is 35468.25, with a leftover of 0.0.
