We look at the division of 139220 by 4 
The aim is to understand the frequency of 4 in 139220.

Let's proceed to step 1:
4 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 4

Advancing to step 2:
4 goes into 13 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 12 from 13 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 4

Let's proceed to step 3:
4 can be fit into 19 4 times, resulting in a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 16 from 19, we get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 4

Step 4:
The number 4 fits into 32 8 times, leaving a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 348.0
If we subtract 32 from 32, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 4

Moving on to step 5:
4 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 3480.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 4

Moving on to step 6:
20 divided by 4 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 34805.0
If we subtract 20 from 20, 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.

Let's proceed to step 7:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 34805.0
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.

Going ahead to step 8:
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: 34805.0
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.

The quotient of the division is 34805.0, and the remainder is 0.0.
