We're dividing 66142876 by 243 
We want to divide 66142876 by 243.

Step 1:
When dividing 6 by 243, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 243

Going ahead to step 2:
66 divided by 243 is 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 243

Advancing to step 3:
661 divided by 243 is 2 with a remainder of 175.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 486 from 661 and we're left with 175.
Bring next digit (4) of the dividend behind the 175 and repeat the process: 1754 / 243

Let's proceed to step 4:
When dividing 1754 by 243, we get 7 with a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Deduct 1701 from 1754 and we're left with 53.
Take the next digit (2) from the dividend and append it to 53, then repeat: 532 / 243

On to step 5:
If we divide 532 by 243, we get 2 and a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 272.0
Subtracting 486 from 532 leaves us with 46.
Take the next digit (8) from the dividend and append it to 46, then repeat: 468 / 243

Advancing to step 6:
The number 243 fits into 468 1 times, leaving a remainder of 225.
Write down 1 as next digit of the result. 
Result so far: 2721.0
The remainder is 225 after subtracting 243 from 468.
Grab the next digit (7) from the dividend, add it to 225, then carry on: 2257 / 243

On to step 7:
If we divide 2257 by 243, we get 9 and a remainder of 70.
Write down 9 as next digit of the result. 
Result so far: 27219.0
Subtract 2187 from 2257 to get 70.
Append the next digit (6) from the dividend to 70 and continue with: 706 / 243

Moving on to step 8:
706 divided by 243 is 2 with a remainder of 220.
Use 2 as the next digit of our solution. 
Result so far: 272192.0
The remainder is 220 after subtracting 486 from 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 9:
243 can be fit into 2200 9 times, resulting in a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 272192.9
Deduct 2187 from 2200 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 10:
243 can be fit into 130 0 times, resulting in a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 272192.9
Subtract 0 from 130 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 11:
1300 divided by 243 is 5 with a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 272192.905
Deduct 1215 from 1300 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 12:
If we divide 850 by 243, we get 3 and a remainder of 121.
Put 3 as the next digit of the answer. 
Result so far: 272192.9053
The remainder is 121 after subtracting 729 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Advancing to step 13:
The number 243 fits into 1210 4 times, leaving a remainder of 238.
Put 4 as the next digit of the answer. 
Result so far: 272192.90534
The remainder is 238 after subtracting 972 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 14:
243 goes into 2380 9 times with a remainder of 193.
Use 9 as the next digit of our solution. 
Result so far: 272192.905349
Subtracting 2187 from 2380 leaves us with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

On to step 15:
243 goes into 1930 7 times with a remainder of 229.
The number 7 becomes the next digit in our result. 
Result so far: 272192.9053497
Subtract 1701 from 1930 to get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Going ahead to step 16:
2290 divided by 243 is 9 with a remainder of 103.
Use 9 as the next digit of our solution. 
Result so far: 272192.90534979
Deduct 2187 from 2290 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

The quotient of the division is 272192.90534979, and the remainder is 1.03e-07.
