49881258 ÷ 243 
We want to divide 49881258 by 243.

On to step 1:
If we divide 4 by 243, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 243

Moving on to step 2:
When dividing 49 by 243, we get 0 with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Take the next digit (8) from the dividend and append it to 49, then repeat: 498 / 243

Moving on to step 3:
243 goes into 498 2 times with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 486 from 498 and we're left with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 243

Step 4:
If we divide 128 by 243, we get 0 and a remainder of 128.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we take 0 away from 128, we end up with 128.
Bring next digit (1) of the dividend behind the 128 and repeat the process: 1281 / 243

Going ahead to step 5:
If we divide 1281 by 243, we get 5 and a remainder of 66.
The number 5 becomes the next digit in our result. 
Result so far: 205.0
The remainder is 66 after subtracting 1215 from 1281.
Grab the next digit (2) from the dividend, add it to 66, then carry on: 662 / 243

Going ahead to step 6:
The number 243 fits into 662 2 times, leaving a remainder of 176.
The number 2 becomes the next digit in our result. 
Result so far: 2052.0
Subtracting 486 from 662 leaves us with 176.
Take the next digit (5) from the dividend and append it to 176, then repeat: 1765 / 243

Moving on to step 7:
243 can be fit into 1765 7 times, resulting in a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 20527.0
Subtracting 1701 from 1765 leaves us with 64.
Fetch the next digit (8) from the dividend, attach it to 64 and continue: 648 / 243

Advancing to step 8:
If we divide 648 by 243, we get 2 and a remainder of 162.
Use 2 as the next digit of our solution. 
Result so far: 205272.0
Deduct 486 from 648 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 9:
The number 243 fits into 1620 6 times, leaving a remainder of 162.
Write down 6 as next digit of the result. 
Result so far: 205272.6
Deduct 1458 from 1620 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 10:
243 goes into 1620 6 times with a remainder of 162.
Write down 6 as next digit of the result. 
Result so far: 205272.66
If we subtract 1458 from 1620, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

The final result is 205272.66 with a remainder of 0.162.
