305389 ÷ 39 
We're looking to find how many times 39 goes into 305389.

Let's proceed to step 1:
39 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 39

Advancing to step 2:
When dividing 30 by 39, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 39

Let's proceed to step 3:
39 goes into 305 7 times with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 273 from 305, we get 32.
Fetch the next digit (3) from the dividend, attach it to 32 and continue: 323 / 39

Going ahead to step 4:
39 can be fit into 323 8 times, resulting in a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
If we take 312 away from 323, we end up with 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 39

On to step 5:
118 divided by 39 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 783.0
If we subtract 117 from 118, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 39

On to step 6:
39 can be fit into 19 0 times, resulting in a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 7830.0
If we take 0 away from 19, 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.

Step 7:
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: 7830.4
Deduct 156 from 190 and we're left 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.

On to step 8:
39 can be fit into 340 8 times, resulting in a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 7830.48
If we take 312 away from 340, we end up 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.

Let's proceed to step 9:
When dividing 280 by 39, we get 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 7830.487
Subtract 273 from 280 to 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 10:
70 divided by 39 is 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 7830.4871
Subtracting 39 from 70 leaves us 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 11:
39 goes into 310 7 times with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 7830.48717
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.

Step 12:
If we divide 370 by 39, we get 9 and a remainder of 19.
The next digit of our result is 9. 
Result so far: 7830.487179
Deduct 351 from 370 and we're left 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.

On to step 13:
The number 39 fits into 190 4 times, leaving a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 7830.4871794
Deduct 156 from 190 and we're left 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.

Moving on to step 14:
If we divide 340 by 39, we get 8 and a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 7830.48717948
Subtracting 312 from 340 leaves us 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.

After the division, we end up with 7830.48717948 and a remainder of 2.8e-08.
