We're dividing 77254245 by 285 
We want to divide 77254245 by 285.

Moving on to step 1:
If we divide 7 by 285, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 285

Going ahead to step 2:
If we divide 77 by 285, we get 0 and a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Append the next digit (2) from the dividend to 77 and continue with: 772 / 285

Let's proceed to step 3:
285 goes into 772 2 times with a remainder of 202.
The next digit of our result is 2. 
Result so far: 2.0
If we take 570 away from 772, we end up with 202.
Take the next digit (5) from the dividend and append it to 202, then repeat: 2025 / 285

Step 4:
285 goes into 2025 7 times with a remainder of 30.
The next digit of our result is 7. 
Result so far: 27.0
Subtract 1995 from 2025 to get 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 285

On to step 5:
If we divide 304 by 285, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 271.0
Subtract 285 from 304 to get 19.
Bring next digit (2) of the dividend behind the 19 and repeat the process: 192 / 285

Going ahead to step 6:
When dividing 192 by 285, we get 0 with a remainder of 192.
Write down 0 as next digit of the result. 
Result so far: 2710.0
If we subtract 0 from 192, we get 192.
Grab the next digit (4) from the dividend, add it to 192, then carry on: 1924 / 285

Moving on to step 7:
285 goes into 1924 6 times with a remainder of 214.
Record the quotient 6 as the next digit in the result. 
Result so far: 27106.0
Deduct 1710 from 1924 and we're left with 214.
Grab the next digit (5) from the dividend, add it to 214, then carry on: 2145 / 285

Step 8:
285 can be fit into 2145 7 times, resulting in a remainder of 150.
Put 7 as the next digit of the answer. 
Result so far: 271067.0
Subtract 1995 from 2145 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 9:
1500 divided by 285 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 271067.5
If we take 1425 away from 1500, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 10:
750 divided by 285 is 2 with a remainder of 180.
The number 2 becomes the next digit in our result. 
Result so far: 271067.52
Subtracting 570 from 750 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 11:
The number 285 fits into 1800 6 times, leaving a remainder of 90.
Use 6 as the next digit of our solution. 
Result so far: 271067.526
Subtracting 1710 from 1800 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 12:
900 divided by 285 is 3 with a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 271067.5263
The remainder is 45 after subtracting 855 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 13:
The number 285 fits into 450 1 times, leaving a remainder of 165.
Put 1 as the next digit of the answer. 
Result so far: 271067.52631
Subtract 285 from 450 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 14:
The number 285 fits into 1650 5 times, leaving a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 271067.526315
The remainder is 225 after subtracting 1425 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 15:
When dividing 2250 by 285, we get 7 with a remainder of 255.
The next digit of our result is 7. 
Result so far: 271067.5263157
Subtracting 1995 from 2250 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 16:
If we divide 2550 by 285, we get 8 and a remainder of 270.
The next digit of our result is 8. 
Result so far: 271067.52631578
Subtract 2280 from 2550 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

In conclusion, the division gives 271067.52631578 with a balance of 2.7e-07.
