We look at the division of 42003729 by 909 
We want to figure out the number of times 42003729 can be divided by 909.

Step 1:
4 divided by 909 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 909

Advancing to step 2:
When dividing 42 by 909, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 909

Moving on to step 3:
The number 909 fits into 420 0 times, leaving a remainder of 420.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 420 and we're left with 420.
Bring next digit (0) of the dividend behind the 420 and repeat the process: 4200 / 909

On to step 4:
When dividing 4200 by 909, we get 4 with a remainder of 564.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 564 after subtracting 3636 from 4200.
Include the next digit (3) from the dividend after 564, then repeat: 5643 / 909

On to step 5:
909 goes into 5643 6 times with a remainder of 189.
Use 6 as the next digit of our solution. 
Result so far: 46.0
If we subtract 5454 from 5643, we get 189.
Fetch the next digit (7) from the dividend, attach it to 189 and continue: 1897 / 909

Going ahead to step 6:
The number 909 fits into 1897 2 times, leaving a remainder of 79.
Write down 2 as next digit of the result. 
Result so far: 462.0
If we take 1818 away from 1897, we end up with 79.
Fetch the next digit (2) from the dividend, attach it to 79 and continue: 792 / 909

Going ahead to step 7:
If we divide 792 by 909, we get 0 and a remainder of 792.
Put 0 as the next digit of the answer. 
Result so far: 4620.0
Deduct 0 from 792 and we're left with 792.
Fetch the next digit (9) from the dividend, attach it to 792 and continue: 7929 / 909

Going ahead to step 8:
7929 divided by 909 is 8 with a remainder of 657.
The next digit of our result is 8. 
Result so far: 46208.0
Subtract 7272 from 7929 to get 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Step 9:
909 goes into 6570 7 times with a remainder of 207.
Record the quotient 7 as the next digit in the result. 
Result so far: 46208.7
If we subtract 6363 from 6570, we get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Going ahead to step 10:
909 goes into 2070 2 times with a remainder of 252.
Record the quotient 2 as the next digit in the result. 
Result so far: 46208.72
Subtracting 1818 from 2070 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 11:
When dividing 2520 by 909, we get 2 with a remainder of 702.
Put 2 as the next digit of the answer. 
Result so far: 46208.722
If we subtract 1818 from 2520, we get 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

The final result is 46208.722 with a remainder of 0.0702.
