39145 ÷ 76 
We're looking to find how many times 76 goes into 39145.

On to step 1:
The number 76 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 76

Advancing to step 2:
If we divide 39 by 76, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 76

Advancing to step 3:
When dividing 391 by 76, we get 5 with a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 11 after subtracting 380 from 391.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 76

Going ahead to step 4:
76 can be fit into 114 1 times, resulting in a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Subtracting 76 from 114 leaves us with 38.
Append the next digit (5) from the dividend to 38 and continue with: 385 / 76

On to step 5:
76 can be fit into 385 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 515.0
Subtract 380 from 385 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 6:
The number 76 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 515.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 7:
76 goes into 500 6 times with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 515.06
If we subtract 456 from 500, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 8:
76 goes into 440 5 times with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 515.065
If we subtract 380 from 440, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
When dividing 600 by 76, we get 7 with a remainder of 68.
The number 7 becomes the next digit in our result. 
Result so far: 515.0657
Subtract 532 from 600 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 10:
76 can be fit into 680 8 times, resulting in a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 515.06578
Subtract 608 from 680 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 11:
When dividing 720 by 76, we get 9 with a remainder of 36.
The next digit of our result is 9. 
Result so far: 515.065789
The remainder is 36 after subtracting 684 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
360 divided by 76 is 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 515.0657894
Subtract 304 from 360 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 13:
76 can be fit into 560 7 times, resulting in a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 515.06578947
Deduct 532 from 560 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.

The final outcome is 515.06578947, with a leftover of 2.8e-08.
