We divide 129599 by 6
Let's see how many times 6 fits into 129599.

Step 1:
6 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 6

Let's proceed to step 2:
The number 6 fits into 12 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 12 from 12, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 6

Going ahead to step 3:
When dividing 9 by 6, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtract 6 from 9 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 6

Step 4:
If we divide 35 by 6, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 215.0
Deduct 30 from 35 and we're left with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 6

Moving on to step 5:
The number 6 fits into 59 9 times, leaving a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 2159.0
The remainder is 5 after subtracting 54 from 59.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 6

Moving on to step 6:
The number 6 fits into 59 9 times, leaving a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 21599.0
Deduct 54 from 59 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
The number 6 fits into 50 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 21599.8
Subtract 48 from 50 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
If we divide 20 by 6, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 21599.83
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
6 goes into 20 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 21599.833
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 21599.833 with a remainder of 0.0002.
