We're dividing 81063961 by 543 
We want to figure out the number of times 81063961 can be divided by 543.

Going ahead to step 1:
The number 543 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 543

On to step 2:
543 goes into 81 0 times with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Append the next digit (0) from the dividend to 81 and continue with: 810 / 543

Going ahead to step 3:
543 goes into 810 1 times with a remainder of 267.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 543 from 810 and we're left with 267.
Grab the next digit (6) from the dividend, add it to 267, then carry on: 2676 / 543

Step 4:
If we divide 2676 by 543, we get 4 and a remainder of 504.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 2172 away from 2676, we end up with 504.
Append the next digit (3) from the dividend to 504 and continue with: 5043 / 543

Advancing to step 5:
543 goes into 5043 9 times with a remainder of 156.
Use 9 as the next digit of our solution. 
Result so far: 149.0
The remainder is 156 after subtracting 4887 from 5043.
Grab the next digit (9) from the dividend, add it to 156, then carry on: 1569 / 543

On to step 6:
543 goes into 1569 2 times with a remainder of 483.
The number 2 becomes the next digit in our result. 
Result so far: 1492.0
Subtracting 1086 from 1569 leaves us with 483.
Fetch the next digit (6) from the dividend, attach it to 483 and continue: 4836 / 543

Moving on to step 7:
543 can be fit into 4836 8 times, resulting in a remainder of 492.
Write down 8 as next digit of the result. 
Result so far: 14928.0
If we subtract 4344 from 4836, we get 492.
Append the next digit (1) from the dividend to 492 and continue with: 4921 / 543

Step 8:
543 goes into 4921 9 times with a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 149289.0
Subtract 4887 from 4921 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
340 divided by 543 is 0 with a remainder of 340.
Put 0 as the next digit of the answer. 
Result so far: 149289.0
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 10:
If we divide 3400 by 543, we get 6 and a remainder of 142.
Put 6 as the next digit of the answer. 
Result so far: 149289.06
If we subtract 3258 from 3400, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 11:
1420 divided by 543 is 2 with a remainder of 334.
The next digit of our result is 2. 
Result so far: 149289.062
If we take 1086 away from 1420, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 12:
543 goes into 3340 6 times with a remainder of 82.
Use 6 as the next digit of our solution. 
Result so far: 149289.0626
Deduct 3258 from 3340 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 13:
If we divide 820 by 543, we get 1 and a remainder of 277.
Put 1 as the next digit of the answer. 
Result so far: 149289.06261
If we take 543 away from 820, we end up with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Moving on to step 14:
2770 divided by 543 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 149289.062615
If we subtract 2715 from 2770, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 15:
543 can be fit into 550 1 times, resulting in a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 149289.0626151
If we take 543 away from 550, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 16:
When dividing 70 by 543, we get 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 149289.0626151
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 149289.0626151, with a leftover of 7e-08.
