187499 ÷ 39 
We're looking to find how many times 39 goes into 187499.

Going ahead to step 1:
The number 39 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 39

Moving on to step 2:
18 divided by 39 is 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 39

Going ahead to step 3:
The number 39 fits into 187 4 times, leaving a remainder of 31.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 156 from 187, we get 31.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 39

Moving on to step 4:
The number 39 fits into 314 8 times, leaving a remainder of 2.
The next digit of our result is 8. 
Result so far: 48.0
If we subtract 312 from 314, we get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 39

Going ahead to step 5:
If we divide 29 by 39, we get 0 and a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 480.0
Subtracting 0 from 29 leaves us with 29.
Take the next digit (9) from the dividend and append it to 29, then repeat: 299 / 39

Going ahead to step 6:
299 divided by 39 is 7 with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 4807.0
Deduct 273 from 299 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
39 can be fit into 260 6 times, resulting in a remainder of 26.
The next digit of our result is 6. 
Result so far: 4807.6
Subtract 234 from 260 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
39 goes into 260 6 times with a remainder of 26.
The next digit of our result is 6. 
Result so far: 4807.66
Deduct 234 from 260 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The quotient of the division is 4807.66, and the remainder is 0.026.
