Let's divide 728458 by 39
Let's see how many times 39 fits into 728458.

Moving on to step 1:
When dividing 7 by 39, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 39

On to step 2:
39 can be fit into 72 1 times, resulting in a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 33 after subtracting 39 from 72.
Bring next digit (8) of the dividend behind the 33 and repeat the process: 338 / 39

On to step 3:
When dividing 338 by 39, we get 8 with a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 312 from 338 and we're left with 26.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 39

Advancing to step 4:
If we divide 264 by 39, we get 6 and a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 186.0
If we take 234 away from 264, we end up with 30.
Take the next digit (5) from the dividend and append it to 30, then repeat: 305 / 39

Step 5:
The number 39 fits into 305 7 times, leaving a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 1867.0
If we take 273 away from 305, we end up with 32.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 39

Step 6:
39 can be fit into 328 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 18678.0
Deduct 312 from 328 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
If we divide 160 by 39, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 18678.4
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
40 divided by 39 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 18678.41
Subtract 39 from 40 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.

Going ahead to step 9:
If we divide 10 by 39, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 18678.41
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
If we divide 100 by 39, we get 2 and a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 18678.4102
Subtracting 78 from 100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
When dividing 220 by 39, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 18678.41025
Subtract 195 from 220 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 12:
39 goes into 250 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 18678.410256
Deduct 234 from 250 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
If we divide 160 by 39, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 18678.4102564
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
39 can be fit into 40 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 18678.41025641
If we subtract 39 from 40, we 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.

The final result is 18678.41025641 with a remainder of 1e-09.
