1640722 ÷ 903 
We're looking to find how many times 903 goes into 1640722.

Moving on to step 1:
The number 903 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 903

Step 2:
16 divided by 903 is 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 903

Going ahead to step 3:
If we divide 164 by 903, we get 0 and a remainder of 164.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 164 after subtracting 0 from 164.
Bring next digit (0) of the dividend behind the 164 and repeat the process: 1640 / 903

Step 4:
If we divide 1640 by 903, we get 1 and a remainder of 737.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 903 from 1640 leaves us with 737.
Fetch the next digit (7) from the dividend, attach it to 737 and continue: 7377 / 903

On to step 5:
7377 divided by 903 is 8 with a remainder of 153.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 7224 from 7377 leaves us with 153.
Bring next digit (2) of the dividend behind the 153 and repeat the process: 1532 / 903

Going ahead to step 6:
If we divide 1532 by 903, we get 1 and a remainder of 629.
Put 1 as the next digit of the answer. 
Result so far: 181.0
Subtracting 903 from 1532 leaves us with 629.
Bring next digit (2) of the dividend behind the 629 and repeat the process: 6292 / 903

Let's proceed to step 7:
The number 903 fits into 6292 6 times, leaving a remainder of 874.
The number 6 becomes the next digit in our result. 
Result so far: 1816.0
Subtract 5418 from 6292 to get 874.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8740, and continue the process.

Going ahead to step 8:
8740 divided by 903 is 9 with a remainder of 613.
Record the quotient 9 as the next digit in the result. 
Result so far: 1816.9
Deduct 8127 from 8740 and we're left with 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

Moving on to step 9:
If we divide 6130 by 903, we get 6 and a remainder of 712.
Use 6 as the next digit of our solution. 
Result so far: 1816.96
Deduct 5418 from 6130 and we're left with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Let's proceed to step 10:
If we divide 7120 by 903, we get 7 and a remainder of 799.
Put 7 as the next digit of the answer. 
Result so far: 1816.967
If we subtract 6321 from 7120, we get 799.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7990, and continue the process.

Going ahead to step 11:
The number 903 fits into 7990 8 times, leaving a remainder of 766.
The next digit of our result is 8. 
Result so far: 1816.9678
The remainder is 766 after subtracting 7224 from 7990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

Step 12:
When dividing 7660 by 903, we get 8 with a remainder of 436.
Record the quotient 8 as the next digit in the result. 
Result so far: 1816.96788
Subtracting 7224 from 7660 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

The final result is 1816.96788 with a remainder of 0.000436.
