Let's divide 76558917 by 243
We want to figure out the number of times 76558917 can be divided by 243.

On to step 1:
The number 243 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 243

Step 2:
243 goes into 76 0 times with a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Take the next digit (5) from the dividend and append it to 76, then repeat: 765 / 243

Going ahead to step 3:
When dividing 765 by 243, we get 3 with a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 729 from 765 and we're left with 36.
Grab the next digit (5) from the dividend, add it to 36, then carry on: 365 / 243

On to step 4:
If we divide 365 by 243, we get 1 and a remainder of 122.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtracting 243 from 365 leaves us with 122.
Append the next digit (8) from the dividend to 122 and continue with: 1228 / 243

Let's proceed to step 5:
When dividing 1228 by 243, we get 5 with a remainder of 13.
The next digit of our result is 5. 
Result so far: 315.0
The remainder is 13 after subtracting 1215 from 1228.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 243

Moving on to step 6:
139 divided by 243 is 0 with a remainder of 139.
Write down 0 as next digit of the result. 
Result so far: 3150.0
Subtract 0 from 139 to get 139.
Take the next digit (1) from the dividend and append it to 139, then repeat: 1391 / 243

Let's proceed to step 7:
1391 divided by 243 is 5 with a remainder of 176.
Record the quotient 5 as the next digit in the result. 
Result so far: 31505.0
Subtract 1215 from 1391 to get 176.
Take the next digit (7) from the dividend and append it to 176, then repeat: 1767 / 243

Advancing to step 8:
When dividing 1767 by 243, we get 7 with a remainder of 66.
The number 7 becomes the next digit in our result. 
Result so far: 315057.0
If we subtract 1701 from 1767, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 9:
If we divide 660 by 243, we get 2 and a remainder of 174.
The number 2 becomes the next digit in our result. 
Result so far: 315057.2
The remainder is 174 after subtracting 486 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 10:
If we divide 1740 by 243, we get 7 and a remainder of 39.
The next digit of our result is 7. 
Result so far: 315057.27
If we subtract 1701 from 1740, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 11:
If we divide 390 by 243, we get 1 and a remainder of 147.
Record the quotient 1 as the next digit in the result. 
Result so far: 315057.271
Subtract 243 from 390 to get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Advancing to step 12:
243 goes into 1470 6 times with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 315057.2716
Deduct 1458 from 1470 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
243 goes into 120 0 times with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 315057.2716
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 14:
243 goes into 1200 4 times with a remainder of 228.
The number 4 becomes the next digit in our result. 
Result so far: 315057.271604
Subtract 972 from 1200 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 15:
2280 divided by 243 is 9 with a remainder of 93.
The next digit of our result is 9. 
Result so far: 315057.2716049
Subtract 2187 from 2280 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 16:
243 can be fit into 930 3 times, resulting in a remainder of 201.
Put 3 as the next digit of the answer. 
Result so far: 315057.27160493
If we subtract 729 from 930, we get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

In conclusion, the division gives 315057.27160493 with a balance of 2.01e-07.
