43230979 ÷ 549 
We want to figure out the number of times 43230979 can be divided by 549.

Step 1:
If we divide 4 by 549, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 549

Advancing to step 2:
549 goes into 43 0 times with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Fetch the next digit (2) from the dividend, attach it to 43 and continue: 432 / 549

Going ahead to step 3:
549 goes into 432 0 times with a remainder of 432.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 432, we end up with 432.
Fetch the next digit (3) from the dividend, attach it to 432 and continue: 4323 / 549

Step 4:
549 goes into 4323 7 times with a remainder of 480.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 480 after subtracting 3843 from 4323.
Fetch the next digit (0) from the dividend, attach it to 480 and continue: 4800 / 549

Advancing to step 5:
The number 549 fits into 4800 8 times, leaving a remainder of 408.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Subtract 4392 from 4800 to get 408.
Include the next digit (9) from the dividend after 408, then repeat: 4089 / 549

Advancing to step 6:
4089 divided by 549 is 7 with a remainder of 246.
The next digit of our result is 7. 
Result so far: 787.0
If we subtract 3843 from 4089, we get 246.
Grab the next digit (7) from the dividend, add it to 246, then carry on: 2467 / 549

Let's proceed to step 7:
When dividing 2467 by 549, we get 4 with a remainder of 271.
Record the quotient 4 as the next digit in the result. 
Result so far: 7874.0
If we subtract 2196 from 2467, we get 271.
Include the next digit (9) from the dividend after 271, then repeat: 2719 / 549

Advancing to step 8:
549 goes into 2719 4 times with a remainder of 523.
Put 4 as the next digit of the answer. 
Result so far: 78744.0
Deduct 2196 from 2719 and we're left with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Step 9:
5230 divided by 549 is 9 with a remainder of 289.
Write down 9 as next digit of the result. 
Result so far: 78744.9
The remainder is 289 after subtracting 4941 from 5230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Moving on to step 10:
549 goes into 2890 5 times with a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 78744.95
If we take 2745 away from 2890, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 11:
The number 549 fits into 1450 2 times, leaving a remainder of 352.
Put 2 as the next digit of the answer. 
Result so far: 78744.952
If we subtract 1098 from 1450, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 12:
3520 divided by 549 is 6 with a remainder of 226.
Use 6 as the next digit of our solution. 
Result so far: 78744.9526
Subtracting 3294 from 3520 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 13:
If we divide 2260 by 549, we get 4 and a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 78744.95264
Subtract 2196 from 2260 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 14:
549 goes into 640 1 times with a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 78744.952641
If we take 549 away from 640, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Let's proceed to step 15:
If we divide 910 by 549, we get 1 and a remainder of 361.
Record the quotient 1 as the next digit in the result. 
Result so far: 78744.9526411
The remainder is 361 after subtracting 549 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

The final result is 78744.9526411 with a remainder of 3.61e-06.
