We're dividing 43909484 by 81 
Our goal is to divide 43909484 by 81.

Step 1:
81 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
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:
43 divided by 81 is 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 81

Step 3:
If we divide 439 by 81, we get 5 and a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 405 from 439 leaves us with 34.
Include the next digit (0) from the dividend after 34, then repeat: 340 / 81

Let's proceed to step 4:
The number 81 fits into 340 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 54.0
The remainder is 16 after subtracting 324 from 340.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 81

On to step 5:
The number 81 fits into 169 2 times, leaving a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 542.0
Deduct 162 from 169 and we're left with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 81

Moving on to step 6:
74 divided by 81 is 0 with a remainder of 74.
The next digit of our result is 0. 
Result so far: 5420.0
Deduct 0 from 74 and we're left with 74.
Grab the next digit (8) from the dividend, add it to 74, then carry on: 748 / 81

Step 7:
748 divided by 81 is 9 with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 54209.0
Subtracting 729 from 748 leaves us with 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 81

Step 8:
The number 81 fits into 194 2 times, leaving a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 542092.0
Deduct 162 from 194 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
When dividing 320 by 81, we get 3 with a remainder of 77.
The number 3 becomes the next digit in our result. 
Result so far: 542092.3
Subtract 243 from 320 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 10:
If we divide 770 by 81, we get 9 and a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 542092.39
Deduct 729 from 770 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 11:
If we divide 410 by 81, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 542092.395
Subtracting 405 from 410 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
81 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 542092.395
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
The number 81 fits into 500 6 times, leaving a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 542092.39506
Subtracting 486 from 500 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 14:
81 can be fit into 140 1 times, resulting in a remainder of 59.
The next digit of our result is 1. 
Result so far: 542092.395061
If we take 81 away from 140, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 15:
590 divided by 81 is 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 542092.3950617
Subtract 567 from 590 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 16:
81 goes into 230 2 times with a remainder of 68.
The next digit of our result is 2. 
Result so far: 542092.39506172
Deduct 162 from 230 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The quotient of the division is 542092.39506172, and the remainder is 6.8e-08.
