Let's divide 450607 by 81
We want to divide 450607 by 81.

On to step 1:
The number 81 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 81

Moving on to step 2:
If we divide 45 by 81, we get 0 and a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Include the next digit (0) from the dividend after 45, then repeat: 450 / 81

Let's proceed to step 3:
When dividing 450 by 81, we get 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 5.0
If we take 405 away from 450, we end up with 45.
Grab the next digit (6) from the dividend, add it to 45, then carry on: 456 / 81

On to step 4:
If we divide 456 by 81, we get 5 and a remainder of 51.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
The remainder is 51 after subtracting 405 from 456.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 81

On to step 5:
81 can be fit into 510 6 times, resulting in a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 556.0
If we subtract 486 from 510, we get 24.
Take the next digit (7) from the dividend and append it to 24, then repeat: 247 / 81

Let's proceed to step 6:
If we divide 247 by 81, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 5563.0
Subtracting 243 from 247 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.

Moving on to step 7:
If we divide 40 by 81, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 5563.0
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
If we divide 400 by 81, we get 4 and a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 5563.04
Deduct 324 from 400 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 9:
The number 81 fits into 760 9 times, leaving a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 5563.049
Subtract 729 from 760 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 10:
The number 81 fits into 310 3 times, leaving a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 5563.0493
The remainder is 67 after subtracting 243 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 11:
The number 81 fits into 670 8 times, leaving a remainder of 22.
The next digit of our result is 8. 
Result so far: 5563.04938
Deduct 648 from 670 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 12:
81 goes into 220 2 times with a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 5563.049382
If we take 162 away from 220, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 13:
81 goes into 580 7 times with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 5563.0493827
The remainder is 13 after subtracting 567 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 14:
When dividing 130 by 81, we get 1 with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 5563.04938271
Subtracting 81 from 130 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final result is 5563.04938271 with a remainder of 4.9e-08.
