We divide 309805 by 39
Let's see how many times 39 fits into 309805.

On to step 1:
39 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 39

Advancing to step 2:
30 divided by 39 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 39

On to step 3:
If we divide 309 by 39, we get 7 and a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 273 from 309, we get 36.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 39

Let's proceed to step 4:
368 divided by 39 is 9 with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 79.0
Deduct 351 from 368 and we're left with 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 39

Advancing to step 5:
The number 39 fits into 170 4 times, leaving a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 794.0
Subtracting 156 from 170 leaves us with 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 39

Going ahead to step 6:
39 can be fit into 145 3 times, resulting in a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 7943.0
The remainder is 28 after subtracting 117 from 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 7:
The number 39 fits into 280 7 times, leaving a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 7943.7
Subtracting 273 from 280 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
The number 39 fits into 70 1 times, leaving a remainder of 31.
The next digit of our result is 1. 
Result so far: 7943.71
Subtract 39 from 70 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
The number 39 fits into 310 7 times, leaving a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 7943.717
If we take 273 away from 310, we end up 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.

On to step 10:
370 divided by 39 is 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 7943.7179
If we take 351 away from 370, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 11:
When dividing 190 by 39, we get 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 7943.71794
Subtracting 156 from 190 leaves us 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.

Let's proceed to step 12:
When dividing 340 by 39, we get 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 7943.717948
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 13:
39 goes into 280 7 times with a remainder of 7.
The next digit of our result is 7. 
Result so far: 7943.7179487
If we take 273 away from 280, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 14:
39 goes into 70 1 times with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 7943.71794871
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.

In conclusion, the division gives 7943.71794871 with a balance of 3.1e-08.
