450451 ÷ 85 
Let's see how many times 85 fits into 450451.

Step 1:
4 divided by 85 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 85

Moving on to step 2:
85 can be fit into 45 0 times, resulting in a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Fetch the next digit (0) from the dividend, attach it to 45 and continue: 450 / 85

On to step 3:
85 can be fit into 450 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 425 away from 450, we end up with 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 85

Let's proceed to step 4:
When dividing 254 by 85, we get 2 with a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
Subtract 170 from 254 to get 84.
Bring next digit (5) of the dividend behind the 84 and repeat the process: 845 / 85

On to step 5:
845 divided by 85 is 9 with a remainder of 80.
The number 9 becomes the next digit in our result. 
Result so far: 529.0
The remainder is 80 after subtracting 765 from 845.
Bring next digit (1) of the dividend behind the 80 and repeat the process: 801 / 85

On to step 6:
When dividing 801 by 85, we get 9 with a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 5299.0
Subtract 765 from 801 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 7:
360 divided by 85 is 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 5299.4
Subtracting 340 from 360 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
200 divided by 85 is 2 with a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 5299.42
If we subtract 170 from 200, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
85 can be fit into 300 3 times, resulting in a remainder of 45.
The next digit of our result is 3. 
Result so far: 5299.423
If we subtract 255 from 300, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 10:
450 divided by 85 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 5299.4235
Deduct 425 from 450 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
The number 85 fits into 250 2 times, leaving a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 5299.42352
If we take 170 away from 250, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
The number 85 fits into 800 9 times, leaving a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 5299.423529
Subtract 765 from 800 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 13:
85 can be fit into 350 4 times, resulting in a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 5299.4235294
Subtract 340 from 350 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
When dividing 100 by 85, we get 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 5299.42352941
Deduct 85 from 100 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 5299.42352941 with a remaining 1.5e-08.
