We divide 1505902 by 639
We want to divide 1505902 by 639.

Let's proceed to step 1:
1 divided by 639 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 639

Let's proceed to step 2:
639 can be fit into 15 0 times, resulting in a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 639

Moving on to step 3:
If we divide 150 by 639, we get 0 and a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 150, we end up with 150.
Bring next digit (5) of the dividend behind the 150 and repeat the process: 1505 / 639

Step 4:
If we divide 1505 by 639, we get 2 and a remainder of 227.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1278 from 1505 and we're left with 227.
Grab the next digit (9) from the dividend, add it to 227, then carry on: 2279 / 639

Moving on to step 5:
2279 divided by 639 is 3 with a remainder of 362.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
The remainder is 362 after subtracting 1917 from 2279.
Append the next digit (0) from the dividend to 362 and continue with: 3620 / 639

Step 6:
3620 divided by 639 is 5 with a remainder of 425.
The next digit of our result is 5. 
Result so far: 235.0
The remainder is 425 after subtracting 3195 from 3620.
Take the next digit (2) from the dividend and append it to 425, then repeat: 4252 / 639

Going ahead to step 7:
4252 divided by 639 is 6 with a remainder of 418.
Write down 6 as next digit of the result. 
Result so far: 2356.0
Subtract 3834 from 4252 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Moving on to step 8:
4180 divided by 639 is 6 with a remainder of 346.
Put 6 as the next digit of the answer. 
Result so far: 2356.6
The remainder is 346 after subtracting 3834 from 4180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Going ahead to step 9:
The number 639 fits into 3460 5 times, leaving a remainder of 265.
Use 5 as the next digit of our solution. 
Result so far: 2356.65
If we take 3195 away from 3460, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 10:
639 goes into 2650 4 times with a remainder of 94.
Put 4 as the next digit of the answer. 
Result so far: 2356.654
Deduct 2556 from 2650 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 11:
639 goes into 940 1 times with a remainder of 301.
Put 1 as the next digit of the answer. 
Result so far: 2356.6541
The remainder is 301 after subtracting 639 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Let's proceed to step 12:
When dividing 3010 by 639, we get 4 with a remainder of 454.
Write down 4 as next digit of the result. 
Result so far: 2356.65414
Subtract 2556 from 3010 to get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

On to step 13:
If we divide 4540 by 639, we get 7 and a remainder of 67.
The next digit of our result is 7. 
Result so far: 2356.654147
Subtracting 4473 from 4540 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 14:
If we divide 670 by 639, we get 1 and a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 2356.6541471
Subtract 639 from 670 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 15:
639 goes into 310 0 times with a remainder of 310.
Record the quotient 0 as the next digit in the result. 
Result so far: 2356.6541471
Subtract 0 from 310 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

After the division, we end up with 2356.6541471 and a remainder of 3.1e-07.
