If we divide 1665 by 355, we get 4 and a remainder of 245.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 1420 from 1665, we get 245.
Grab the next digit (9) from the dividend, add it to 245, then carry on: 2459 / 355

Going ahead to step 5:
355 goes into 2459 6 times with a remainder of 329.
The next digit of our result is 6. 
Result so far: 46.0
The remainder is 329 after subtracting 2130 from 2459.
Fetch the next digit (7) from the dividend, attach it to 329 and continue: 3297 / 355

Step 6:
The number 355 fits into 3297 9 times, leaving a remainder of 102.
Put 9 as the next digit of the answer. 
Result so far: 469.0
If we subtract 3195 from 3297, we get 102.
Bring next digit (8) of the dividend behind the 102 and repeat the process: 1028 / 355

On to step 7:
If we divide 1028 by 355, we get 2 and a remainder of 318.
Record the quotient 2 as the next digit in the result. 
Result so far: 4692.0
Subtract 710 from 1028 to get 318.
Append the next digit (9) from the dividend to 318 and continue with: 3189 / 355

Moving on to step 8:
355 goes into 3189 8 times with a remainder of 349.
Write down 8 as next digit of the result. 
Result so far: 46928.0
Subtract 2840 from 3189 to get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Step 9:
3490 divided by 355 is 9 with a remainder of 295.
Put 9 as the next digit of the answer. 
Result so far: 46928.9
Subtracting 3195 from 3490 leaves us with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Moving on to step 10:
355 can be fit into 2950 8 times, resulting in a remainder of 110.
The number 8 becomes the next digit in our result. 
Result so far: 46928.98
Deduct 2840 from 2950 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 11:
When dividing 1100 by 355, we get 3 with a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 46928.983
Deduct 1065 from 1100 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
355 goes into 350 0 times with a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 46928.983
Subtract 0 from 350 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 13:
355 goes into 3500 9 times with a remainder of 305.
Record the quotient 9 as the next digit in the result. 
Result so far: 46928.98309
Subtracting 3195 from 3500 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 14:
3050 divided by 355 is 8 with a remainder of 210.
The number 8 becomes the next digit in our result. 
Result so far: 46928.983098
Subtract 2840 from 3050 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 15:
355 goes into 2100 5 times with a remainder of 325.
The next digit of our result is 5. 
Result so far: 46928.9830985
Subtracting 1775 from 2100 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Let's proceed to step 16:
355 goes into 3250 9 times with a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 46928.98309859
Deduct 3195 from 3250 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

After the division, we end up with 46928.98309859 and a remainder of 5.5e-08.
