39438189 divided by 305 
We're looking to find how many times 305 goes into 39438189.

Let's proceed to step 1:
If we divide 3 by 305, we get 0 and 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.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 305

On to step 2:
39 divided by 305 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Include the next digit (4) from the dividend after 39, then repeat: 394 / 305

Going ahead to step 3:
305 can be fit into 394 1 times, resulting in a remainder of 89.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 305 from 394 to get 89.
Include the next digit (3) from the dividend after 89, then repeat: 893 / 305

On to step 4:
893 divided by 305 is 2 with a remainder of 283.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 610 from 893 leaves us with 283.
Grab the next digit (8) from the dividend, add it to 283, then carry on: 2838 / 305

Advancing to step 5:
305 goes into 2838 9 times with a remainder of 93.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
The remainder is 93 after subtracting 2745 from 2838.
Grab the next digit (1) from the dividend, add it to 93, then carry on: 931 / 305

Step 6:
The number 305 fits into 931 3 times, leaving a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 1293.0
Subtract 915 from 931 to get 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 305

Step 7:
305 can be fit into 168 0 times, resulting in a remainder of 168.
Put 0 as the next digit of the answer. 
Result so far: 12930.0
Deduct 0 from 168 and we're left with 168.
Bring next digit (9) of the dividend behind the 168 and repeat the process: 1689 / 305

Step 8:
305 can be fit into 1689 5 times, resulting in a remainder of 164.
The number 5 becomes the next digit in our result. 
Result so far: 129305.0
The remainder is 164 after subtracting 1525 from 1689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 9:
1640 divided by 305 is 5 with a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 129305.5
Subtracting 1525 from 1640 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 10:
If we divide 1150 by 305, we get 3 and a remainder of 235.
Write down 3 as next digit of the result. 
Result so far: 129305.53
Subtract 915 from 1150 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Moving on to step 11:
305 can be fit into 2350 7 times, resulting in a remainder of 215.
The number 7 becomes the next digit in our result. 
Result so far: 129305.537
Subtract 2135 from 2350 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 12:
The number 305 fits into 2150 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 129305.5377
Subtract 2135 from 2150 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 129305.5377 with a remainder of 0.00015.
