446623 ÷ 81 
We want to divide 446623 by 81.

Step 1:
If we divide 4 by 81, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 81

Moving on to step 2:
81 can be fit into 44 0 times, resulting in a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 44, we get 44.
Grab the next digit (6) from the dividend, add it to 44, then carry on: 446 / 81

Let's proceed to step 3:
446 divided by 81 is 5 with a remainder of 41.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 405 from 446, we get 41.
Bring next digit (6) of the dividend behind the 41 and repeat the process: 416 / 81

Advancing to step 4:
The number 81 fits into 416 5 times, leaving a remainder of 11.
The next digit of our result is 5. 
Result so far: 55.0
Subtracting 405 from 416 leaves us with 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 81

On to step 5:
The number 81 fits into 112 1 times, leaving a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 551.0
If we subtract 81 from 112, we get 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 81

On to step 6:
81 goes into 313 3 times with a remainder of 70.
Write down 3 as next digit of the result. 
Result so far: 5513.0
Deduct 243 from 313 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 7:
700 divided by 81 is 8 with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 5513.8
Subtracting 648 from 700 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 8:
The number 81 fits into 520 6 times, leaving a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 5513.86
Deduct 486 from 520 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
The number 81 fits into 340 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 5513.864
Subtract 324 from 340 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
If we divide 160 by 81, we get 1 and a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 5513.8641
Subtract 81 from 160 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 11:
790 divided by 81 is 9 with a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 5513.86419
Subtracting 729 from 790 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 12:
81 goes into 610 7 times with a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 5513.864197
The remainder is 43 after subtracting 567 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 13:
If we divide 430 by 81, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 5513.8641975
If we take 405 away from 430, we end up 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.

Going ahead to step 14:
If we divide 250 by 81, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 5513.86419753
Subtracting 243 from 250 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 5513.86419753, with a leftover of 7e-09.
