We're dividing 728605 by 39 
We want to figure out the number of times 728605 can be divided by 39.

Going ahead to step 1:
39 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 39

Moving on to step 2:
When dividing 72 by 39, we get 1 with a remainder of 33.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 33 after subtracting 39 from 72.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 39

Going ahead to step 3:
39 can be fit into 338 8 times, resulting in a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we subtract 312 from 338, we get 26.
Bring next digit (6) of the dividend behind the 26 and repeat the process: 266 / 39

Going ahead to step 4:
The number 39 fits into 266 6 times, leaving a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 186.0
Subtract 234 from 266 to get 32.
Grab the next digit (0) from the dividend, add it to 32, then carry on: 320 / 39

Moving on to step 5:
39 goes into 320 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 1868.0
Subtract 312 from 320 to get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 39

Let's proceed to step 6:
When dividing 85 by 39, we get 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 18682.0
The remainder is 7 after subtracting 78 from 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
If we divide 70 by 39, we get 1 and a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 18682.1
If we take 39 away from 70, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 8:
If we divide 310 by 39, we get 7 and a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 18682.17
Deduct 273 from 310 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 9:
39 can be fit into 370 9 times, resulting in a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 18682.179
Subtract 351 from 370 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 10:
When dividing 190 by 39, we get 4 with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 18682.1794
If we take 156 away from 190, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 11:
If we divide 340 by 39, we get 8 and a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 18682.17948
If we subtract 312 from 340, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
When dividing 280 by 39, we get 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 18682.179487
If we subtract 273 from 280, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 13:
39 goes into 70 1 times with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 18682.1794871
If we take 39 away from 70, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 14:
When dividing 310 by 39, we get 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 18682.17948717
The remainder is 37 after subtracting 273 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final outcome is 18682.17948717, with a leftover of 3.7e-08.
