52939 ÷ 15 
We're looking to find how many times 15 goes into 52939.

Going ahead to step 1:
15 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 15

Moving on to step 2:
The number 15 fits into 52 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 45 from 52 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 15

Step 3:
15 can be fit into 79 5 times, resulting in a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 35.0
If we subtract 75 from 79, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 15

Going ahead to step 4:
When dividing 43 by 15, we get 2 with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 352.0
Deduct 30 from 43 and we're left with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 15

Going ahead to step 5:
When dividing 139 by 15, we get 9 with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 3529.0
Deduct 135 from 139 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 6:
If we divide 40 by 15, we get 2 and a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 3529.2
If we take 30 away from 40, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
If we divide 100 by 15, we get 6 and a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 3529.26
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
100 divided by 15 is 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 3529.266
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 3529.266, and the remainder is 0.001.
