If we divide 2902 by 646, we get 4 and a remainder of 318.
The next digit of our result is 4. 
Result so far: 6014.0
Deduct 2584 from 2902 and we're left with 318.
Fetch the next digit (5) from the dividend, attach it to 318 and continue: 3185 / 646

Step 8:
When dividing 3185 by 646, we get 4 with a remainder of 601.
The next digit of our result is 4. 
Result so far: 60144.0
If we take 2584 away from 3185, we end up with 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Going ahead to step 9:
646 can be fit into 6010 9 times, resulting in a remainder of 196.
The next digit of our result is 9. 
Result so far: 60144.9
If we subtract 5814 from 6010, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 10:
646 can be fit into 1960 3 times, resulting in a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 60144.93
Subtracting 1938 from 1960 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 11:
646 goes into 220 0 times with a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 60144.93
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 12:
When dividing 2200 by 646, we get 3 with a remainder of 262.
The next digit of our result is 3. 
Result so far: 60144.9303
Subtract 1938 from 2200 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 13:
When dividing 2620 by 646, we get 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 60144.93034
If we subtract 2584 from 2620, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 14:
646 goes into 360 0 times with a remainder of 360.
The number 0 becomes the next digit in our result. 
Result so far: 60144.93034
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 15:
646 goes into 3600 5 times with a remainder of 370.
Record the quotient 5 as the next digit in the result. 
Result so far: 60144.9303405
Deduct 3230 from 3600 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 16:
If we divide 3700 by 646, we get 5 and a remainder of 470.
The number 5 becomes the next digit in our result. 
Result so far: 60144.93034055
Subtracting 3230 from 3700 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Our division results in 60144.93034055 with a remaining 4.7e-07.
