We look at the division of 234489 by 45 
Our goal is to divide 234489 by 45.

Moving on to step 1:
If we divide 2 by 45, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 45

Advancing to step 2:
23 divided by 45 is 0 with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Bring next digit (4) of the dividend behind the 23 and repeat the process: 234 / 45

Advancing to step 3:
When dividing 234 by 45, we get 5 with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 225 from 234, we get 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 45

Step 4:
94 divided by 45 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 52.0
The remainder is 4 after subtracting 90 from 94.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 45

Step 5:
The number 45 fits into 48 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 521.0
Deduct 45 from 48 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 45

Going ahead to step 6:
If we divide 39 by 45, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 5210.0
If we subtract 0 from 39, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
The number 45 fits into 390 8 times, leaving a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 5210.8
Subtracting 360 from 390 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
300 divided by 45 is 6 with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 5210.86
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
45 goes into 300 6 times with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 5210.866
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 5210.866 with a remainder of 0.003.
