We're dividing 78875363 by 243 
We want to figure out the number of times 78875363 can be divided by 243.

Moving on to step 1:
If we divide 7 by 243, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 243

Advancing to step 2:
243 can be fit into 78 0 times, resulting in a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 243

Moving on to step 3:
If we divide 788 by 243, we get 3 and a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 729 from 788 to get 59.
Bring next digit (7) of the dividend behind the 59 and repeat the process: 597 / 243

Step 4:
The number 243 fits into 597 2 times, leaving a remainder of 111.
The next digit of our result is 2. 
Result so far: 32.0
If we take 486 away from 597, we end up with 111.
Grab the next digit (5) from the dividend, add it to 111, then carry on: 1115 / 243

Advancing to step 5:
243 goes into 1115 4 times with a remainder of 143.
Put 4 as the next digit of the answer. 
Result so far: 324.0
If we take 972 away from 1115, we end up with 143.
Fetch the next digit (3) from the dividend, attach it to 143 and continue: 1433 / 243

Moving on to step 6:
When dividing 1433 by 243, we get 5 with a remainder of 218.
Record the quotient 5 as the next digit in the result. 
Result so far: 3245.0
Deduct 1215 from 1433 and we're left with 218.
Append the next digit (6) from the dividend to 218 and continue with: 2186 / 243

Step 7:
The number 243 fits into 2186 8 times, leaving a remainder of 242.
Put 8 as the next digit of the answer. 
Result so far: 32458.0
Subtracting 1944 from 2186 leaves us with 242.
Append the next digit (3) from the dividend to 242 and continue with: 2423 / 243

Going ahead to step 8:
2423 divided by 243 is 9 with a remainder of 236.
Record the quotient 9 as the next digit in the result. 
Result so far: 324589.0
If we take 2187 away from 2423, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 9:
The number 243 fits into 2360 9 times, leaving a remainder of 173.
Record the quotient 9 as the next digit in the result. 
Result so far: 324589.9
Subtract 2187 from 2360 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Step 10:
If we divide 1730 by 243, we get 7 and a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 324589.97
If we subtract 1701 from 1730, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 11:
When dividing 290 by 243, we get 1 with a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 324589.971
The remainder is 47 after subtracting 243 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 12:
The number 243 fits into 470 1 times, leaving a remainder of 227.
Record the quotient 1 as the next digit in the result. 
Result so far: 324589.9711
If we subtract 243 from 470, we get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

In conclusion, the division gives 324589.9711 with a balance of 0.00227.
