145837 divided by 45 
Let's see how many times 45 fits into 145837.

Going ahead to step 1:
The number 45 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 45

Let's proceed to step 2:
45 can be fit into 14 0 times, resulting in a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 45

Let's proceed to step 3:
If we divide 145 by 45, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 135 from 145 and we're left with 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 45

Advancing to step 4:
45 can be fit into 108 2 times, resulting in a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Subtract 90 from 108 to get 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 45

On to step 5:
45 can be fit into 183 4 times, resulting in a remainder of 3.
The next digit of our result is 4. 
Result so far: 324.0
Deduct 180 from 183 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 45

Let's proceed to step 6:
37 divided by 45 is 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 3240.0
Subtracting 0 from 37 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
370 divided by 45 is 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 3240.8
Subtract 360 from 370 to 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.

Going ahead to step 8:
If we divide 100 by 45, we get 2 and a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 3240.82
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.

On to step 9:
When dividing 100 by 45, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 3240.822
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.

The final result is 3240.822 with a remainder of 0.001.
