We're dividing 168991 by 6 
We want to divide 168991 by 6.

Advancing to step 1:
1 divided by 6 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 6

Let's proceed to step 2:
When dividing 16 by 6, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 4 after subtracting 12 from 16.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 6

Advancing to step 3:
6 goes into 48 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Deduct 48 from 48 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 6

Moving on to step 4:
6 can be fit into 9 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 281.0
Subtract 6 from 9 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 6

Let's proceed to step 5:
6 goes into 39 6 times with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 2816.0
Deduct 36 from 39 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 6

Advancing to step 6:
6 can be fit into 31 5 times, resulting in a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 28165.0
If we subtract 30 from 31, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
If we divide 10 by 6, we get 1 and a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 28165.1
Subtracting 6 from 10 leaves us 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 8:
When dividing 40 by 6, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 28165.16
Subtracting 36 from 40 leaves us 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 9:
When dividing 40 by 6, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 28165.166
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 28165.166, and the remainder is 0.0004.
