We look at the division of 43003042 by 900 
Our goal is to divide 43003042 by 900.

Moving on to step 1:
4 divided by 900 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 900

Advancing to step 2:
900 goes into 43 0 times with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 900

On to step 3:
900 goes into 430 0 times with a remainder of 430.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 430 and we're left with 430.
Fetch the next digit (0) from the dividend, attach it to 430 and continue: 4300 / 900

Let's proceed to step 4:
When dividing 4300 by 900, we get 4 with a remainder of 700.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 3600 from 4300 to get 700.
Fetch the next digit (3) from the dividend, attach it to 700 and continue: 7003 / 900

On to step 5:
The number 900 fits into 7003 7 times, leaving a remainder of 703.
Write down 7 as next digit of the result. 
Result so far: 47.0
Subtracting 6300 from 7003 leaves us with 703.
Include the next digit (0) from the dividend after 703, then repeat: 7030 / 900

Let's proceed to step 6:
7030 divided by 900 is 7 with a remainder of 730.
Use 7 as the next digit of our solution. 
Result so far: 477.0
Subtracting 6300 from 7030 leaves us with 730.
Include the next digit (4) from the dividend after 730, then repeat: 7304 / 900

Step 7:
900 goes into 7304 8 times with a remainder of 104.
Put 8 as the next digit of the answer. 
Result so far: 4778.0
Deduct 7200 from 7304 and we're left with 104.
Take the next digit (2) from the dividend and append it to 104, then repeat: 1042 / 900

Moving on to step 8:
The number 900 fits into 1042 1 times, leaving a remainder of 142.
Use 1 as the next digit of our solution. 
Result so far: 47781.0
Subtract 900 from 1042 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Going ahead to step 9:
900 goes into 1420 1 times with a remainder of 520.
Record the quotient 1 as the next digit in the result. 
Result so far: 47781.1
Deduct 900 from 1420 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 10:
5200 divided by 900 is 5 with a remainder of 700.
The next digit of our result is 5. 
Result so far: 47781.15
If we take 4500 away from 5200, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 11:
The number 900 fits into 7000 7 times, leaving a remainder of 700.
Write down 7 as next digit of the result. 
Result so far: 47781.157
If we subtract 6300 from 7000, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 12:
7000 divided by 900 is 7 with a remainder of 700.
Write down 7 as next digit of the result. 
Result so far: 47781.1577
Deduct 6300 from 7000 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The quotient of the division is 47781.1577, and the remainder is 0.007.
