453991 ÷ 6 
Our goal is to divide 453991 by 6.

Step 1:
4 divided by 6 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 6

Moving on to step 2:
6 goes into 45 7 times with a remainder of 3.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 42 from 45, we get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 6

Going ahead to step 3:
The number 6 fits into 33 5 times, leaving a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 75.0
The remainder is 3 after subtracting 30 from 33.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 6

Let's proceed to step 4:
39 divided by 6 is 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 756.0
Subtract 36 from 39 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 6

On to step 5:
6 goes into 39 6 times with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 7566.0
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:
The number 6 fits into 31 5 times, leaving a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 75665.0
Subtracting 30 from 31 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
10 divided by 6 is 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 75665.1
If we take 6 away from 10, we end up 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:
6 goes into 40 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 75665.16
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.

Let's proceed to step 9:
40 divided by 6 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 75665.166
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.

Our division results in 75665.166 with a remaining 0.0004.
