We look at the division of 451670 by 5 
Our goal is to divide 451670 by 5.

Let's proceed to step 1:
The number 5 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 5

Going ahead to step 2:
The number 5 fits into 45 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 45 from 45 and we're left with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 5

Step 3:
If we divide 1 by 5, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 90.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 5

Going ahead to step 4:
5 goes into 16 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 903.0
If we subtract 15 from 16, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 5

Step 5:
5 can be fit into 17 3 times, resulting in a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 9033.0
The remainder is 2 after subtracting 15 from 17.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 5

Step 6:
5 goes into 20 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 90334.0
Subtracting 20 from 20 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:
5 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 90334.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
The number 5 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 90334.0
The remainder is 0 after subtracting 0 from 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 final result is 90334.0 with a remainder of 0.0.
