We're dividing 39573515 by 543 
We want to divide 39573515 by 543.

Let's proceed to step 1:
If we divide 3 by 543, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 543

Going ahead to step 2:
543 can be fit into 39 0 times, resulting in a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Append the next digit (5) from the dividend to 39 and continue with: 395 / 543

Going ahead to step 3:
543 can be fit into 395 0 times, resulting in a remainder of 395.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 395, we get 395.
Bring next digit (7) of the dividend behind the 395 and repeat the process: 3957 / 543

Let's proceed to step 4:
543 goes into 3957 7 times with a remainder of 156.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 3801 from 3957 and we're left with 156.
Fetch the next digit (3) from the dividend, attach it to 156 and continue: 1563 / 543

Let's proceed to step 5:
543 goes into 1563 2 times with a remainder of 477.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
If we take 1086 away from 1563, we end up with 477.
Fetch the next digit (5) from the dividend, attach it to 477 and continue: 4775 / 543

Step 6:
When dividing 4775 by 543, we get 8 with a remainder of 431.
The next digit of our result is 8. 
Result so far: 728.0
If we take 4344 away from 4775, we end up with 431.
Include the next digit (1) from the dividend after 431, then repeat: 4311 / 543

Advancing to step 7:
The number 543 fits into 4311 7 times, leaving a remainder of 510.
Put 7 as the next digit of the answer. 
Result so far: 7287.0
If we take 3801 away from 4311, we end up with 510.
Bring next digit (5) of the dividend behind the 510 and repeat the process: 5105 / 543

On to step 8:
543 goes into 5105 9 times with a remainder of 218.
The number 9 becomes the next digit in our result. 
Result so far: 72879.0
Subtract 4887 from 5105 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 9:
When dividing 2180 by 543, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 72879.4
If we take 2172 away from 2180, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
543 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 72879.4
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
543 can be fit into 800 1 times, resulting in a remainder of 257.
Use 1 as the next digit of our solution. 
Result so far: 72879.401
Deduct 543 from 800 and we're left with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Advancing to step 12:
When dividing 2570 by 543, we get 4 with a remainder of 398.
Record the quotient 4 as the next digit in the result. 
Result so far: 72879.4014
Subtracting 2172 from 2570 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Advancing to step 13:
543 can be fit into 3980 7 times, resulting in a remainder of 179.
Put 7 as the next digit of the answer. 
Result so far: 72879.40147
Subtracting 3801 from 3980 leaves us with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Step 14:
543 can be fit into 1790 3 times, resulting in a remainder of 161.
Record the quotient 3 as the next digit in the result. 
Result so far: 72879.401473
Subtract 1629 from 1790 to get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Going ahead to step 15:
If we divide 1610 by 543, we get 2 and a remainder of 524.
Put 2 as the next digit of the answer. 
Result so far: 72879.4014732
If we take 1086 away from 1610, we end up with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

On to step 16:
543 can be fit into 5240 9 times, resulting in a remainder of 353.
Record the quotient 9 as the next digit in the result. 
Result so far: 72879.40147329
Subtract 4887 from 5240 to get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

After the division, we end up with 72879.40147329 and a remainder of 3.53e-07.
