We look at the division of 309043 by 39 
Let's see how many times 39 fits into 309043.

On to step 1:
If we divide 3 by 39, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 39

Going ahead to step 2:
When dividing 30 by 39, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 39

On to step 3:
309 divided by 39 is 7 with a remainder of 36.
The next digit of our result is 7. 
Result so far: 7.0
If we take 273 away from 309, we end up with 36.
Take the next digit (0) from the dividend and append it to 36, then repeat: 360 / 39

Advancing to step 4:
39 can be fit into 360 9 times, resulting in a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Deduct 351 from 360 and we're left with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 39

Step 5:
39 goes into 94 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 792.0
The remainder is 16 after subtracting 78 from 94.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 39

Moving on to step 6:
163 divided by 39 is 4 with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 7924.0
If we subtract 156 from 163, 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.

Let's proceed to step 7:
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: 7924.1
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.

Moving on to step 8:
The number 39 fits into 310 7 times, leaving a remainder of 37.
The next digit of our result is 7. 
Result so far: 7924.17
Subtract 273 from 310 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 9:
When dividing 370 by 39, we get 9 with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 7924.179
Subtracting 351 from 370 leaves us 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 10:
39 goes into 190 4 times with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 7924.1794
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.

Advancing to step 11:
39 goes into 340 8 times with a remainder of 28.
The next digit of our result is 8. 
Result so far: 7924.17948
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:
If we divide 280 by 39, we get 7 and a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 7924.179487
Deduct 273 from 280 and we're left 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 13:
39 can be fit into 70 1 times, resulting in a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 7924.1794871
Deduct 39 from 70 and we're left 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.

Step 14:
39 can be fit into 310 7 times, resulting in a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 7924.17948717
Subtract 273 from 310 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

In conclusion, the division gives 7924.17948717 with a balance of 3.7e-08.
