We look at the division of 49434789 by 243 
Our goal is to divide 49434789 by 243.

On to step 1:
When dividing 4 by 243, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 243

Let's proceed to step 2:
49 divided by 243 is 0 with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Bring next digit (4) of the dividend behind the 49 and repeat the process: 494 / 243

Moving on to step 3:
When dividing 494 by 243, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 8 after subtracting 486 from 494.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 243

On to step 4:
83 divided by 243 is 0 with a remainder of 83.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 83, we get 83.
Fetch the next digit (4) from the dividend, attach it to 83 and continue: 834 / 243

Step 5:
If we divide 834 by 243, we get 3 and a remainder of 105.
Write down 3 as next digit of the result. 
Result so far: 203.0
Deduct 729 from 834 and we're left with 105.
Include the next digit (7) from the dividend after 105, then repeat: 1057 / 243

On to step 6:
243 goes into 1057 4 times with a remainder of 85.
Write down 4 as next digit of the result. 
Result so far: 2034.0
Subtracting 972 from 1057 leaves us with 85.
Grab the next digit (8) from the dividend, add it to 85, then carry on: 858 / 243

Advancing to step 7:
243 goes into 858 3 times with a remainder of 129.
Put 3 as the next digit of the answer. 
Result so far: 20343.0
Subtract 729 from 858 to get 129.
Grab the next digit (9) from the dividend, add it to 129, then carry on: 1299 / 243

On to step 8:
243 can be fit into 1299 5 times, resulting in a remainder of 84.
Use 5 as the next digit of our solution. 
Result so far: 203435.0
Deduct 1215 from 1299 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 9:
If we divide 840 by 243, we get 3 and a remainder of 111.
Record the quotient 3 as the next digit in the result. 
Result so far: 203435.3
Deduct 729 from 840 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 10:
1110 divided by 243 is 4 with a remainder of 138.
Record the quotient 4 as the next digit in the result. 
Result so far: 203435.34
The remainder is 138 after subtracting 972 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 11:
1380 divided by 243 is 5 with a remainder of 165.
Put 5 as the next digit of the answer. 
Result so far: 203435.345
The remainder is 165 after subtracting 1215 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 12:
1650 divided by 243 is 6 with a remainder of 192.
The next digit of our result is 6. 
Result so far: 203435.3456
If we subtract 1458 from 1650, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 13:
The number 243 fits into 1920 7 times, leaving a remainder of 219.
Write down 7 as next digit of the result. 
Result so far: 203435.34567
If we take 1701 away from 1920, we end up with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

On to step 14:
2190 divided by 243 is 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 203435.345679
If we take 2187 away from 2190, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 15:
243 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 203435.345679
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 16:
243 can be fit into 300 1 times, resulting in a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 203435.34567901
If we subtract 243 from 300, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

After the division, we end up with 203435.34567901 and a remainder of 5.7e-08.
