We divide 138009 by 4
We want to figure out the number of times 138009 can be divided by 4.

Moving on to step 1:
4 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 4

On to step 2:
4 can be fit into 13 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 12 from 13 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 4

Moving on to step 3:
The number 4 fits into 18 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
The remainder is 2 after subtracting 16 from 18.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 4

Let's proceed to step 4:
When dividing 20 by 4, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 345.0
The remainder is 0 after subtracting 20 from 20.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 4

On to step 5:
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: 3450.0
Subtract 0 from 0 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 4

Step 6:
When dividing 9 by 4, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 34502.0
The remainder is 1 after subtracting 8 from 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
When dividing 10 by 4, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 34502.2
Subtracting 8 from 10 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
4 goes into 20 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 34502.25
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.

On to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 34502.25
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:
When dividing 0 by 4, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 34502.25
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.

Our division results in 34502.25 with a remaining 0.0.
