We look at the division of 991971 by 6 
We want to figure out the number of times 991971 can be divided by 6.

Advancing to step 1:
The number 6 fits into 9 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 6 from 9 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 6

Advancing to step 2:
6 can be fit into 39 6 times, resulting in a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 36 away from 39, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 6

Going ahead to step 3:
If we divide 31 by 6, we get 5 and a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 165.0
If we subtract 30 from 31, we get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 6

On to step 4:
The number 6 fits into 19 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 1653.0
If we subtract 18 from 19, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 6

Moving on to step 5:
When dividing 17 by 6, we get 2 with a remainder of 5.
The next digit of our result is 2. 
Result so far: 16532.0
The remainder is 5 after subtracting 12 from 17.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 6

Let's proceed to step 6:
If we divide 51 by 6, we get 8 and a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 165328.0
Subtracting 48 from 51 leaves us with 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.
Write down 5 as next digit of the result. 
Result so far: 165328.5
Subtracting 30 from 30 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.

Let's proceed to step 8:
0 divided by 6 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 165328.5
If we take 0 away from 0, 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.

Let's proceed to step 9:
When dividing 0 by 6, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 165328.5
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.

The quotient of the division is 165328.5, and the remainder is 0.0.
