Let's divide 452549 by 81
We want to figure out the number of times 452549 can be divided by 81.

Advancing to step 1:
81 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 81

Let's proceed to step 2:
If we divide 45 by 81, we get 0 and a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Bring next digit (2) of the dividend behind the 45 and repeat the process: 452 / 81

Going ahead to step 3:
The number 81 fits into 452 5 times, leaving a remainder of 47.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 405 from 452 leaves us with 47.
Take the next digit (5) from the dividend and append it to 47, then repeat: 475 / 81

On to step 4:
When dividing 475 by 81, we get 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 55.0
The remainder is 70 after subtracting 405 from 475.
Include the next digit (4) from the dividend after 70, then repeat: 704 / 81

Going ahead to step 5:
81 can be fit into 704 8 times, resulting in a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 558.0
Subtracting 648 from 704 leaves us with 56.
Bring next digit (9) of the dividend behind the 56 and repeat the process: 569 / 81

Advancing to step 6:
The number 81 fits into 569 7 times, leaving a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 5587.0
Subtracting 567 from 569 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
If we divide 20 by 81, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 5587.0
Deduct 0 from 20 and we're left 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.

Advancing to step 8:
The number 81 fits into 200 2 times, leaving a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 5587.02
If we take 162 away from 200, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
When dividing 380 by 81, we get 4 with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 5587.024
The remainder is 56 after subtracting 324 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
81 can be fit into 560 6 times, resulting in a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 5587.0246
Subtract 486 from 560 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 11:
If we divide 740 by 81, we get 9 and a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 5587.02469
If we subtract 729 from 740, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 12:
The number 81 fits into 110 1 times, leaving a remainder of 29.
The next digit of our result is 1. 
Result so far: 5587.024691
Subtract 81 from 110 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 13:
If we divide 290 by 81, we get 3 and a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 5587.0246913
Subtracting 243 from 290 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 14:
The number 81 fits into 470 5 times, leaving a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 5587.02469135
Subtract 405 from 470 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 5587.02469135 with a remainder of 6.5e-08.
