We divide 132451 by 18
We're looking to find how many times 18 goes into 132451.

On to step 1:
1 divided by 18 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 18

Step 2:
The number 18 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 18

Step 3:
132 divided by 18 is 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 6 after subtracting 126 from 132.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 18

Going ahead to step 4:
When dividing 64 by 18, we get 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
Deduct 54 from 64 and we're left with 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 18

On to step 5:
When dividing 105 by 18, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 735.0
If we take 90 away from 105, we end up with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 18

Moving on to step 6:
151 divided by 18 is 8 with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 7358.0
The remainder is 7 after subtracting 144 from 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
18 can be fit into 70 3 times, resulting in a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 7358.3
If we take 54 away from 70, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
18 can be fit into 160 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 7358.38
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
18 can be fit into 160 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 7358.388
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 7358.388 with a remainder of 0.0016.
