Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 355

On to step 2:
The number 355 fits into 85 0 times, leaving a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Fetch the next digit (9) from the dividend, attach it to 85 and continue: 859 / 355

Advancing to step 3:
355 goes into 859 2 times with a remainder of 149.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 710 from 859 leaves us with 149.
Take the next digit (1) from the dividend and append it to 149, then repeat: 1491 / 355

Going ahead to step 4:
The number 355 fits into 1491 4 times, leaving a remainder of 71.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtract 1420 from 1491 to get 71.
Grab the next digit (6) from the dividend, add it to 71, then carry on: 716 / 355

Let's proceed to step 5:
If we divide 716 by 355, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 242.0
Deduct 710 from 716 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 355

Let's proceed to step 6:
355 goes into 66 0 times with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 2420.0
If we subtract 0 from 66, we get 66.
Fetch the next digit (3) from the dividend, attach it to 66 and continue: 663 / 355

Step 7:
355 goes into 663 1 times with a remainder of 308.
Write down 1 as next digit of the result. 
Result so far: 24201.0
Subtracting 355 from 663 leaves us with 308.
Fetch the next digit (9) from the dividend, attach it to 308 and continue: 3089 / 355

On to step 8:
If we divide 3089 by 355, we get 8 and a remainder of 249.
Record the quotient 8 as the next digit in the result. 
Result so far: 242018.0
Subtracting 2840 from 3089 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Going ahead to step 9:
When dividing 2490 by 355, we get 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 242018.7
Subtract 2485 from 2490 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 10:
355 can be fit into 50 0 times, resulting in a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 242018.7
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
When dividing 500 by 355, we get 1 with a remainder of 145.
The number 1 becomes the next digit in our result. 
Result so far: 242018.701
Subtracting 355 from 500 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 12:
The number 355 fits into 1450 4 times, leaving a remainder of 30.
The next digit of our result is 4. 
Result so far: 242018.7014
If we subtract 1420 from 1450, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
The number 355 fits into 300 0 times, leaving a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 242018.7014
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 14:
If we divide 3000 by 355, we get 8 and a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 242018.701408
Deduct 2840 from 3000 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 15:
If we divide 1600 by 355, we get 4 and a remainder of 180.
Put 4 as the next digit of the answer. 
Result so far: 242018.7014084
The remainder is 180 after subtracting 1420 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 16:
355 goes into 1800 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 242018.70140845
Deduct 1775 from 1800 and we're left 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.

The final result is 242018.70140845 with a remainder of 2.5e-08.
