We're dividing 42018543 by 229 
We want to divide 42018543 by 229.

Step 1:
229 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 229

On to step 2:
If we divide 42 by 229, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 229

Moving on to step 3:
229 goes into 420 1 times with a remainder of 191.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 229 from 420 to get 191.
Fetch the next digit (1) from the dividend, attach it to 191 and continue: 1911 / 229

Step 4:
If we divide 1911 by 229, we get 8 and a remainder of 79.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 1832 from 1911, we get 79.
Take the next digit (8) from the dividend and append it to 79, then repeat: 798 / 229

Going ahead to step 5:
229 can be fit into 798 3 times, resulting in a remainder of 111.
The next digit of our result is 3. 
Result so far: 183.0
Subtracting 687 from 798 leaves us with 111.
Append the next digit (5) from the dividend to 111 and continue with: 1115 / 229

Moving on to step 6:
1115 divided by 229 is 4 with a remainder of 199.
Use 4 as the next digit of our solution. 
Result so far: 1834.0
Subtracting 916 from 1115 leaves us with 199.
Include the next digit (4) from the dividend after 199, then repeat: 1994 / 229

Advancing to step 7:
229 goes into 1994 8 times with a remainder of 162.
The number 8 becomes the next digit in our result. 
Result so far: 18348.0
If we subtract 1832 from 1994, we get 162.
Fetch the next digit (3) from the dividend, attach it to 162 and continue: 1623 / 229

Going ahead to step 8:
1623 divided by 229 is 7 with a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 183487.0
If we take 1603 away from 1623, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
229 can be fit into 200 0 times, resulting in a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 183487.0
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 10:
2000 divided by 229 is 8 with a remainder of 168.
The next digit of our result is 8. 
Result so far: 183487.08
Subtract 1832 from 2000 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 11:
If we divide 1680 by 229, we get 7 and a remainder of 77.
The next digit of our result is 7. 
Result so far: 183487.087
Deduct 1603 from 1680 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 12:
If we divide 770 by 229, we get 3 and a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 183487.0873
If we take 687 away from 770, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 13:
If we divide 830 by 229, we get 3 and a remainder of 143.
The number 3 becomes the next digit in our result. 
Result so far: 183487.08733
The remainder is 143 after subtracting 687 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Our division results in 183487.08733 with a remaining 0.000143.
