We're dividing 18132441 by 642 
Let's see how many times 642 fits into 18132441.

Advancing to step 1:
642 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 642

Moving on to step 2:
When dividing 18 by 642, we get 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 642

On to step 3:
When dividing 181 by 642, we get 0 with a remainder of 181.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 181, we end up with 181.
Fetch the next digit (3) from the dividend, attach it to 181 and continue: 1813 / 642

On to step 4:
642 can be fit into 1813 2 times, resulting in a remainder of 529.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 1284 from 1813, we get 529.
Append the next digit (2) from the dividend to 529 and continue with: 5292 / 642

Moving on to step 5:
When dividing 5292 by 642, we get 8 with a remainder of 156.
The next digit of our result is 8. 
Result so far: 28.0
Subtract 5136 from 5292 to get 156.
Bring next digit (4) of the dividend behind the 156 and repeat the process: 1564 / 642

Advancing to step 6:
642 can be fit into 1564 2 times, resulting in a remainder of 280.
Use 2 as the next digit of our solution. 
Result so far: 282.0
If we take 1284 away from 1564, we end up with 280.
Bring next digit (4) of the dividend behind the 280 and repeat the process: 2804 / 642

Step 7:
When dividing 2804 by 642, we get 4 with a remainder of 236.
Write down 4 as next digit of the result. 
Result so far: 2824.0
If we take 2568 away from 2804, we end up with 236.
Fetch the next digit (1) from the dividend, attach it to 236 and continue: 2361 / 642

Step 8:
If we divide 2361 by 642, we get 3 and a remainder of 435.
The next digit of our result is 3. 
Result so far: 28243.0
Subtract 1926 from 2361 to get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Going ahead to step 9:
642 can be fit into 4350 6 times, resulting in a remainder of 498.
Record the quotient 6 as the next digit in the result. 
Result so far: 28243.6
If we take 3852 away from 4350, we end up with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

On to step 10:
642 can be fit into 4980 7 times, resulting in a remainder of 486.
Put 7 as the next digit of the answer. 
Result so far: 28243.67
Subtracting 4494 from 4980 leaves us with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Step 11:
642 can be fit into 4860 7 times, resulting in a remainder of 366.
The next digit of our result is 7. 
Result so far: 28243.677
Subtracting 4494 from 4860 leaves us with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

In conclusion, the division gives 28243.677 with a balance of 0.0366.
