64311405 divided by 285 
Our goal is to divide 64311405 by 285.

Step 1:
When dividing 6 by 285, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 285

Moving on to step 2:
285 can be fit into 64 0 times, resulting in a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Fetch the next digit (3) from the dividend, attach it to 64 and continue: 643 / 285

Going ahead to step 3:
When dividing 643 by 285, we get 2 with a remainder of 73.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 570 from 643 to get 73.
Bring next digit (1) of the dividend behind the 73 and repeat the process: 731 / 285

Step 4:
285 can be fit into 731 2 times, resulting in a remainder of 161.
The next digit of our result is 2. 
Result so far: 22.0
If we take 570 away from 731, we end up with 161.
Bring next digit (1) of the dividend behind the 161 and repeat the process: 1611 / 285

Step 5:
When dividing 1611 by 285, we get 5 with a remainder of 186.
Write down 5 as next digit of the result. 
Result so far: 225.0
If we take 1425 away from 1611, we end up with 186.
Take the next digit (4) from the dividend and append it to 186, then repeat: 1864 / 285

Going ahead to step 6:
285 can be fit into 1864 6 times, resulting in a remainder of 154.
Write down 6 as next digit of the result. 
Result so far: 2256.0
The remainder is 154 after subtracting 1710 from 1864.
Append the next digit (0) from the dividend to 154 and continue with: 1540 / 285

Moving on to step 7:
If we divide 1540 by 285, we get 5 and a remainder of 115.
The next digit of our result is 5. 
Result so far: 22565.0
Subtract 1425 from 1540 to get 115.
Fetch the next digit (5) from the dividend, attach it to 115 and continue: 1155 / 285

Going ahead to step 8:
When dividing 1155 by 285, we get 4 with a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 225654.0
Subtract 1140 from 1155 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
150 divided by 285 is 0 with a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 225654.0
Subtracting 0 from 150 leaves us 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.

Let's proceed to step 10:
285 goes into 1500 5 times with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 225654.05
If we subtract 1425 from 1500, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 11:
750 divided by 285 is 2 with a remainder of 180.
The next digit of our result is 2. 
Result so far: 225654.052
The remainder is 180 after subtracting 570 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 12:
The number 285 fits into 1800 6 times, leaving a remainder of 90.
Write down 6 as next digit of the result. 
Result so far: 225654.0526
The remainder is 90 after subtracting 1710 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 13:
285 can be fit into 900 3 times, resulting in a remainder of 45.
Record the quotient 3 as the next digit in the result. 
Result so far: 225654.05263
Deduct 855 from 900 and we're left with 45.
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 14:
285 goes into 450 1 times with a remainder of 165.
Use 1 as the next digit of our solution. 
Result so far: 225654.052631
Deduct 285 from 450 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 15:
The number 285 fits into 1650 5 times, leaving a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 225654.0526315
Subtract 1425 from 1650 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 16:
2250 divided by 285 is 7 with a remainder of 255.
Put 7 as the next digit of the answer. 
Result so far: 225654.05263157
Deduct 1995 from 2250 and we're left 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.

After the division, we end up with 225654.05263157 and a remainder of 2.55e-07.
