We're dividing 81545882 by 450 
We want to figure out the number of times 81545882 can be divided by 450.

Advancing to step 1:
8 divided by 450 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 450

Let's proceed to step 2:
450 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Fetch the next digit (5) from the dividend, attach it to 81 and continue: 815 / 450

On to step 3:
When dividing 815 by 450, we get 1 with a remainder of 365.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 365 after subtracting 450 from 815.
Fetch the next digit (4) from the dividend, attach it to 365 and continue: 3654 / 450

Step 4:
450 can be fit into 3654 8 times, resulting in a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 3600 from 3654, we get 54.
Include the next digit (5) from the dividend after 54, then repeat: 545 / 450

Advancing to step 5:
450 goes into 545 1 times with a remainder of 95.
Use 1 as the next digit of our solution. 
Result so far: 181.0
Subtracting 450 from 545 leaves us with 95.
Fetch the next digit (8) from the dividend, attach it to 95 and continue: 958 / 450

Let's proceed to step 6:
If we divide 958 by 450, we get 2 and a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 1812.0
Subtracting 900 from 958 leaves us with 58.
Fetch the next digit (8) from the dividend, attach it to 58 and continue: 588 / 450

Advancing to step 7:
588 divided by 450 is 1 with a remainder of 138.
Write down 1 as next digit of the result. 
Result so far: 18121.0
If we take 450 away from 588, we end up with 138.
Bring next digit (2) of the dividend behind the 138 and repeat the process: 1382 / 450

Going ahead to step 8:
450 goes into 1382 3 times with a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 181213.0
Subtracting 1350 from 1382 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
320 divided by 450 is 0 with a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 181213.0
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 10:
3200 divided by 450 is 7 with a remainder of 50.
Record the quotient 7 as the next digit in the result. 
Result so far: 181213.07
The remainder is 50 after subtracting 3150 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
500 divided by 450 is 1 with a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 181213.071
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
If we divide 500 by 450, we get 1 and a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 181213.0711
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 181213.0711 with a remaining 0.0005.
