142534 divided by 45 
We want to figure out the number of times 142534 can be divided by 45.

On to step 1:
45 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 45

Advancing to step 2:
The number 45 fits into 14 0 times, leaving a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 45

Step 3:
142 divided by 45 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 7 after subtracting 135 from 142.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 45

On to step 4:
The number 45 fits into 75 1 times, leaving a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Deduct 45 from 75 and we're left with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 45

Let's proceed to step 5:
45 goes into 303 6 times with a remainder of 33.
Record the quotient 6 as the next digit in the result. 
Result so far: 316.0
Subtract 270 from 303 to get 33.
Include the next digit (4) from the dividend after 33, then repeat: 334 / 45

Step 6:
45 goes into 334 7 times with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 3167.0
Subtract 315 from 334 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
The number 45 fits into 190 4 times, leaving a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 3167.4
Deduct 180 from 190 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
If we divide 100 by 45, we get 2 and a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 3167.42
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
When dividing 100 by 45, we get 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 3167.422
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 3167.422 with a remaining 0.001.
