991377 ÷ 3 
We want to figure out the number of times 991377 can be divided by 3.

On to step 1:
3 can be fit into 9 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 9 from 9 and we're left with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 3

Going ahead to step 2:
If we divide 9 by 3, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we subtract 9 from 9, we get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 3

On to step 3:
1 divided by 3 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 330.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 3

On to step 4:
When dividing 13 by 3, we get 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 3304.0
The remainder is 1 after subtracting 12 from 13.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 3

On to step 5:
When dividing 17 by 3, we get 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 33045.0
If we subtract 15 from 17, we get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 3

Moving on to step 6:
The number 3 fits into 27 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 330459.0
Subtracting 27 from 27 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 7:
0 divided by 3 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 330459.0
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.

Advancing to step 8:
When dividing 0 by 3, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 330459.0
If we subtract 0 from 0, we 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.

Our division results in 330459.0 with a remaining 0.0.
