We divide 538404 by 39
Let's see how many times 39 fits into 538404.

Moving on to step 1:
If we divide 5 by 39, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 39

Let's proceed to step 2:
When dividing 53 by 39, we get 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 39 from 53 leaves us with 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 39

Step 3:
39 can be fit into 148 3 times, resulting in a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 117 away from 148, we end up with 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 39

On to step 4:
39 goes into 314 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
Subtract 312 from 314 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 39

On to step 5:
If we divide 20 by 39, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 1380.0
If we take 0 away from 20, we end up with 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 39

Let's proceed to step 6:
204 divided by 39 is 5 with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 13805.0
If we take 195 away from 204, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
The number 39 fits into 90 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 13805.2
Deduct 78 from 90 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
120 divided by 39 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 13805.23
Deduct 117 from 120 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.

Moving on to step 9:
The number 39 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 13805.23
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
When dividing 300 by 39, we get 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 13805.2307
If we take 273 away from 300, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 11:
39 can be fit into 270 6 times, resulting in a remainder of 36.
The next digit of our result is 6. 
Result so far: 13805.23076
Deduct 234 from 270 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
The number 39 fits into 360 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 13805.230769
If we take 351 away from 360, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
The number 39 fits into 90 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 13805.2307692
If we subtract 78 from 90, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
The number 39 fits into 120 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 13805.23076923
Subtract 117 from 120 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 13805.23076923, with a leftover of 3e-09.
