We're dividing 77503218 by 243 
We want to figure out the number of times 77503218 can be divided by 243.

Let's proceed to step 1:
243 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 243

Let's proceed to step 2:
77 divided by 243 is 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Grab the next digit (5) from the dividend, add it to 77, then carry on: 775 / 243

Let's proceed to step 3:
When dividing 775 by 243, we get 3 with a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 729 from 775 to get 46.
Take the next digit (0) from the dividend and append it to 46, then repeat: 460 / 243

Going ahead to step 4:
460 divided by 243 is 1 with a remainder of 217.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtracting 243 from 460 leaves us with 217.
Append the next digit (3) from the dividend to 217 and continue with: 2173 / 243

Going ahead to step 5:
If we divide 2173 by 243, we get 8 and a remainder of 229.
The next digit of our result is 8. 
Result so far: 318.0
If we subtract 1944 from 2173, we get 229.
Append the next digit (2) from the dividend to 229 and continue with: 2292 / 243

Advancing to step 6:
2292 divided by 243 is 9 with a remainder of 105.
Use 9 as the next digit of our solution. 
Result so far: 3189.0
Deduct 2187 from 2292 and we're left with 105.
Append the next digit (1) from the dividend to 105 and continue with: 1051 / 243

On to step 7:
When dividing 1051 by 243, we get 4 with a remainder of 79.
Put 4 as the next digit of the answer. 
Result so far: 31894.0
Subtract 972 from 1051 to get 79.
Include the next digit (8) from the dividend after 79, then repeat: 798 / 243

Step 8:
The number 243 fits into 798 3 times, leaving a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 318943.0
If we take 729 away from 798, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 9:
690 divided by 243 is 2 with a remainder of 204.
Use 2 as the next digit of our solution. 
Result so far: 318943.2
Subtracting 486 from 690 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 10:
If we divide 2040 by 243, we get 8 and a remainder of 96.
The next digit of our result is 8. 
Result so far: 318943.28
Deduct 1944 from 2040 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 11:
When dividing 960 by 243, we get 3 with a remainder of 231.
Write down 3 as next digit of the result. 
Result so far: 318943.283
If we subtract 729 from 960, we get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Advancing to step 12:
The number 243 fits into 2310 9 times, leaving a remainder of 123.
The number 9 becomes the next digit in our result. 
Result so far: 318943.2839
If we take 2187 away from 2310, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Advancing to step 13:
243 goes into 1230 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 318943.28395
The remainder is 15 after subtracting 1215 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 14:
The number 243 fits into 150 0 times, leaving a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 318943.28395
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 15:
243 can be fit into 1500 6 times, resulting in a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 318943.2839506
Subtracting 1458 from 1500 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 16:
If we divide 420 by 243, we get 1 and a remainder of 177.
The next digit of our result is 1. 
Result so far: 318943.28395061
If we subtract 243 from 420, we get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

In conclusion, the division gives 318943.28395061 with a balance of 1.77e-07.
