438833 ÷ 81 
We want to figure out the number of times 438833 can be divided by 81.

Moving on to step 1:
81 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 81

Let's proceed to step 2:
The number 81 fits into 43 0 times, leaving a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Include the next digit (8) from the dividend after 43, then repeat: 438 / 81

Going ahead to step 3:
The number 81 fits into 438 5 times, leaving a remainder of 33.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 33 after subtracting 405 from 438.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 81

Let's proceed to step 4:
81 can be fit into 338 4 times, resulting in a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
If we take 324 away from 338, we end up with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 81

Moving on to step 5:
143 divided by 81 is 1 with a remainder of 62.
The next digit of our result is 1. 
Result so far: 541.0
If we subtract 81 from 143, we get 62.
Fetch the next digit (3) from the dividend, attach it to 62 and continue: 623 / 81

Let's proceed to step 6:
81 can be fit into 623 7 times, resulting in a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 5417.0
Subtract 567 from 623 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 7:
81 can be fit into 560 6 times, resulting in a remainder of 74.
The next digit of our result is 6. 
Result so far: 5417.6
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 8:
The number 81 fits into 740 9 times, leaving a remainder of 11.
The next digit of our result is 9. 
Result so far: 5417.69
Subtract 729 from 740 to 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.

On to step 9:
When dividing 110 by 81, we get 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 5417.691
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.

Moving on to step 10:
The number 81 fits into 290 3 times, leaving a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 5417.6913
If we take 243 away from 290, we end up 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.

On to step 11:
When dividing 470 by 81, we get 5 with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 5417.69135
The remainder is 65 after subtracting 405 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 12:
81 can be fit into 650 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 5417.691358
If we take 648 away from 650, we end up 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.

On to step 13:
The number 81 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 5417.691358
If we take 0 away from 20, we end up 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.

Let's proceed to step 14:
200 divided by 81 is 2 with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 5417.69135802
Deduct 162 from 200 and we're left 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.

Our division results in 5417.69135802 with a remaining 3.8e-08.
