We divide 152139 by 6
We're looking to find how many times 6 goes into 152139.

Advancing to step 1:
1 divided by 6 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 6

Let's proceed to step 2:
When dividing 15 by 6, we get 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 3 after subtracting 12 from 15.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 6

Advancing to step 3:
6 can be fit into 32 5 times, resulting in a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtract 30 from 32 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 6

Step 4:
The number 6 fits into 21 3 times, leaving a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 253.0
Deduct 18 from 21 and we're left with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 6

Let's proceed to step 5:
6 goes into 33 5 times with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 2535.0
Deduct 30 from 33 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 6

On to step 6:
The number 6 fits into 39 6 times, leaving a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 25356.0
If we subtract 36 from 39, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
6 goes into 30 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 25356.5
If we take 30 away from 30, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
If we divide 0 by 6, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 25356.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
6 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25356.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 25356.5 with a remainder of 0.0.
