Let's divide 63109357 by 243
We want to figure out the number of times 63109357 can be divided by 243.

Advancing to step 1:
The number 243 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 243

Step 2:
If we divide 63 by 243, we get 0 and a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Append the next digit (1) from the dividend to 63 and continue with: 631 / 243

On to step 3:
When dividing 631 by 243, we get 2 with a remainder of 145.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 486 from 631 leaves us with 145.
Bring next digit (0) of the dividend behind the 145 and repeat the process: 1450 / 243

Moving on to step 4:
When dividing 1450 by 243, we get 5 with a remainder of 235.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we subtract 1215 from 1450, we get 235.
Bring next digit (9) of the dividend behind the 235 and repeat the process: 2359 / 243

Advancing to step 5:
243 goes into 2359 9 times with a remainder of 172.
Use 9 as the next digit of our solution. 
Result so far: 259.0
Deduct 2187 from 2359 and we're left with 172.
Fetch the next digit (3) from the dividend, attach it to 172 and continue: 1723 / 243

Advancing to step 6:
1723 divided by 243 is 7 with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 2597.0
The remainder is 22 after subtracting 1701 from 1723.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 243

Step 7:
The number 243 fits into 225 0 times, leaving a remainder of 225.
Use 0 as the next digit of our solution. 
Result so far: 25970.0
Subtracting 0 from 225 leaves us with 225.
Take the next digit (7) from the dividend and append it to 225, then repeat: 2257 / 243

Moving on to step 8:
If we divide 2257 by 243, we get 9 and a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 259709.0
If we take 2187 away from 2257, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
If we divide 700 by 243, we get 2 and a remainder of 214.
Record the quotient 2 as the next digit in the result. 
Result so far: 259709.2
Deduct 486 from 700 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 10:
243 goes into 2140 8 times with a remainder of 196.
Use 8 as the next digit of our solution. 
Result so far: 259709.28
Subtracting 1944 from 2140 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 11:
1960 divided by 243 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 259709.288
Deduct 1944 from 1960 and we're left 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.

The quotient of the division is 259709.288, and the remainder is 0.0016.
