We divide 645823 by 39
We're looking to find how many times 39 goes into 645823.

Moving on to step 1:
If we divide 6 by 39, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 39

Advancing to step 2:
If we divide 64 by 39, we get 1 and a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 25 after subtracting 39 from 64.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 39

Going ahead to step 3:
255 divided by 39 is 6 with a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 234 from 255 to get 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 39

On to step 4:
218 divided by 39 is 5 with a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 165.0
Deduct 195 from 218 and we're left with 23.
Grab the next digit (2) from the dividend, add it to 23, then carry on: 232 / 39

Moving on to step 5:
When dividing 232 by 39, we get 5 with a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 1655.0
The remainder is 37 after subtracting 195 from 232.
Include the next digit (3) from the dividend after 37, then repeat: 373 / 39

Advancing to step 6:
The number 39 fits into 373 9 times, leaving a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 16559.0
If we subtract 351 from 373, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
If we divide 220 by 39, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 16559.5
If we take 195 away from 220, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 8:
When dividing 250 by 39, we get 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 16559.56
If we subtract 234 from 250, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
160 divided by 39 is 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 16559.564
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.

Advancing to step 10:
The number 39 fits into 40 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 16559.5641
Deduct 39 from 40 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 11:
39 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 16559.5641
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
When dividing 100 by 39, we get 2 with a remainder of 22.
The next digit of our result is 2. 
Result so far: 16559.564102
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
39 can be fit into 220 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 16559.5641025
Deduct 195 from 220 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 14:
If we divide 250 by 39, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 16559.56410256
The remainder is 16 after subtracting 234 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 16559.56410256 with a balance of 1.6e-08.
