We look at the division of 73872691 by 543 
We want to divide 73872691 by 543.

Moving on to step 1:
If we divide 7 by 543, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 543

Going ahead to step 2:
If we divide 73 by 543, we get 0 and a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Fetch the next digit (8) from the dividend, attach it to 73 and continue: 738 / 543

Let's proceed to step 3:
543 goes into 738 1 times with a remainder of 195.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 543 from 738 to get 195.
Include the next digit (7) from the dividend after 195, then repeat: 1957 / 543

Moving on to step 4:
When dividing 1957 by 543, we get 3 with a remainder of 328.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 1629 from 1957, we get 328.
Bring next digit (2) of the dividend behind the 328 and repeat the process: 3282 / 543

Advancing to step 5:
3282 divided by 543 is 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
Subtracting 3258 from 3282 leaves us with 24.
Include the next digit (6) from the dividend after 24, then repeat: 246 / 543

Step 6:
543 goes into 246 0 times with a remainder of 246.
Put 0 as the next digit of the answer. 
Result so far: 1360.0
The remainder is 246 after subtracting 0 from 246.
Append the next digit (9) from the dividend to 246 and continue with: 2469 / 543

Going ahead to step 7:
If we divide 2469 by 543, we get 4 and a remainder of 297.
Write down 4 as next digit of the result. 
Result so far: 13604.0
If we take 2172 away from 2469, we end up with 297.
Bring next digit (1) of the dividend behind the 297 and repeat the process: 2971 / 543

Moving on to step 8:
The number 543 fits into 2971 5 times, leaving a remainder of 256.
Use 5 as the next digit of our solution. 
Result so far: 136045.0
Subtract 2715 from 2971 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 9:
543 goes into 2560 4 times with a remainder of 388.
The next digit of our result is 4. 
Result so far: 136045.4
If we subtract 2172 from 2560, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 10:
The number 543 fits into 3880 7 times, leaving a remainder of 79.
The next digit of our result is 7. 
Result so far: 136045.47
Subtracting 3801 from 3880 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 11:
790 divided by 543 is 1 with a remainder of 247.
Put 1 as the next digit of the answer. 
Result so far: 136045.471
Subtract 543 from 790 to get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Going ahead to step 12:
If we divide 2470 by 543, we get 4 and a remainder of 298.
Record the quotient 4 as the next digit in the result. 
Result so far: 136045.4714
The remainder is 298 after subtracting 2172 from 2470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Step 13:
2980 divided by 543 is 5 with a remainder of 265.
Use 5 as the next digit of our solution. 
Result so far: 136045.47145
Deduct 2715 from 2980 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 14:
2650 divided by 543 is 4 with a remainder of 478.
The next digit of our result is 4. 
Result so far: 136045.471454
The remainder is 478 after subtracting 2172 from 2650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Advancing to step 15:
If we divide 4780 by 543, we get 8 and a remainder of 436.
Write down 8 as next digit of the result. 
Result so far: 136045.4714548
If we subtract 4344 from 4780, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Advancing to step 16:
543 goes into 4360 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 136045.47145488
Subtracting 4344 from 4360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 136045.47145488 with a remaining 1.6e-08.
