1284215 ÷ 355 
Let's see how many times 355 fits into 1284215.

Going ahead to step 1:
When dividing 1 by 355, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 355

Going ahead to step 2:
355 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 355

Advancing to step 3:
355 goes into 128 0 times with a remainder of 128.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 128, we get 128.
Take the next digit (4) from the dividend and append it to 128, then repeat: 1284 / 355

Step 4:
The number 355 fits into 1284 3 times, leaving a remainder of 219.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 219 after subtracting 1065 from 1284.
Append the next digit (2) from the dividend to 219 and continue with: 2192 / 355

Moving on to step 5:
355 goes into 2192 6 times with a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtracting 2130 from 2192 leaves us with 62.
Append the next digit (1) from the dividend to 62 and continue with: 621 / 355

Let's proceed to step 6:
If we divide 621 by 355, we get 1 and a remainder of 266.
Record the quotient 1 as the next digit in the result. 
Result so far: 361.0
If we subtract 355 from 621, we get 266.
Bring next digit (5) of the dividend behind the 266 and repeat the process: 2665 / 355

Moving on to step 7:
The number 355 fits into 2665 7 times, leaving a remainder of 180.
The number 7 becomes the next digit in our result. 
Result so far: 3617.0
If we take 2485 away from 2665, we end up 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.

Moving on to step 8:
355 goes into 1800 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 3617.5
Subtracting 1775 from 1800 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
When dividing 250 by 355, we get 0 with a remainder of 250.
The next digit of our result is 0. 
Result so far: 3617.5
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 10:
When dividing 2500 by 355, we get 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 3617.507
Subtract 2485 from 2500 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.

Going ahead to step 11:
150 divided by 355 is 0 with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 3617.507
If we subtract 0 from 150, we 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 12:
The number 355 fits into 1500 4 times, leaving a remainder of 80.
The next digit of our result is 4. 
Result so far: 3617.50704
The remainder is 80 after subtracting 1420 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
355 can be fit into 800 2 times, resulting in a remainder of 90.
Use 2 as the next digit of our solution. 
Result so far: 3617.507042
Deduct 710 from 800 and we're left 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.

Moving on to step 14:
If we divide 900 by 355, we get 2 and a remainder of 190.
Write down 2 as next digit of the result. 
Result so far: 3617.5070422
Subtracting 710 from 900 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

After the division, we end up with 3617.5070422 and a remainder of 1.9e-06.
