Let's divide 2102393 by 665
Our goal is to divide 2102393 by 665.

Advancing to step 1:
2 divided by 665 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 665

Step 2:
665 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 665

Going ahead to step 3:
210 divided by 665 is 0 with a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 210 after subtracting 0 from 210.
Include the next digit (2) from the dividend after 210, then repeat: 2102 / 665

Advancing to step 4:
2102 divided by 665 is 3 with a remainder of 107.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 1995 from 2102 and we're left with 107.
Include the next digit (3) from the dividend after 107, then repeat: 1073 / 665

Step 5:
665 can be fit into 1073 1 times, resulting in a remainder of 408.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Deduct 665 from 1073 and we're left with 408.
Fetch the next digit (9) from the dividend, attach it to 408 and continue: 4089 / 665

Step 6:
665 can be fit into 4089 6 times, resulting in a remainder of 99.
Write down 6 as next digit of the result. 
Result so far: 316.0
The remainder is 99 after subtracting 3990 from 4089.
Take the next digit (3) from the dividend and append it to 99, then repeat: 993 / 665

Step 7:
When dividing 993 by 665, we get 1 with a remainder of 328.
Write down 1 as next digit of the result. 
Result so far: 3161.0
The remainder is 328 after subtracting 665 from 993.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 8:
665 can be fit into 3280 4 times, resulting in a remainder of 620.
Write down 4 as next digit of the result. 
Result so far: 3161.4
If we take 2660 away from 3280, we end up with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 9:
665 can be fit into 6200 9 times, resulting in a remainder of 215.
Put 9 as the next digit of the answer. 
Result so far: 3161.49
The remainder is 215 after subtracting 5985 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 10:
When dividing 2150 by 665, we get 3 with a remainder of 155.
Write down 3 as next digit of the result. 
Result so far: 3161.493
If we subtract 1995 from 2150, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 11:
The number 665 fits into 1550 2 times, leaving a remainder of 220.
The next digit of our result is 2. 
Result so far: 3161.4932
Subtract 1330 from 1550 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 12:
If we divide 2200 by 665, we get 3 and a remainder of 205.
Record the quotient 3 as the next digit in the result. 
Result so far: 3161.49323
If we subtract 1995 from 2200, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Advancing to step 13:
665 goes into 2050 3 times with a remainder of 55.
The next digit of our result is 3. 
Result so far: 3161.493233
Subtract 1995 from 2050 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The quotient of the division is 3161.493233, and the remainder is 5.5e-06.
