We look at the division of 19458 by 39 
We're looking to find how many times 39 goes into 19458.

Advancing to step 1:
When dividing 1 by 39, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 39

Let's proceed to step 2:
39 goes into 19 0 times with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 39

On to step 3:
39 can be fit into 194 4 times, resulting in a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 156 away from 194, we end up with 38.
Take the next digit (5) from the dividend and append it to 38, then repeat: 385 / 39

Advancing to step 4:
When dividing 385 by 39, we get 9 with a remainder of 34.
The next digit of our result is 9. 
Result so far: 49.0
The remainder is 34 after subtracting 351 from 385.
Take the next digit (8) from the dividend and append it to 34, then repeat: 348 / 39

On to step 5:
The number 39 fits into 348 8 times, leaving a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 498.0
Subtracting 312 from 348 leaves us 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.

On to step 6:
39 can be fit into 360 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 498.9
If we subtract 351 from 360, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
The number 39 fits into 90 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 498.92
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.

Moving on to step 8:
120 divided by 39 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 498.923
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.

Advancing to step 9:
39 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 498.923
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
39 can be fit into 300 7 times, resulting in a remainder of 27.
The next digit of our result is 7. 
Result so far: 498.92307
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.

Let's proceed to step 11:
39 goes into 270 6 times with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 498.923076
Subtract 234 from 270 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 12:
If we divide 360 by 39, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 498.9230769
Deduct 351 from 360 and we're left 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.

On to step 13:
90 divided by 39 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 498.92307692
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.

In conclusion, the division gives 498.92307692 with a balance of 1.2e-08.
