81853286 ÷ 45 
Our goal is to divide 81853286 by 45.

Advancing to step 1:
45 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 45

Going ahead to step 2:
The number 45 fits into 81 1 times, leaving a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 45 away from 81, we end up with 36.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 45

Advancing to step 3:
45 can be fit into 368 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 18.0
The remainder is 8 after subtracting 360 from 368.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 45

Let's proceed to step 4:
The number 45 fits into 85 1 times, leaving a remainder of 40.
The next digit of our result is 1. 
Result so far: 181.0
If we subtract 45 from 85, we get 40.
Include the next digit (3) from the dividend after 40, then repeat: 403 / 45

Advancing to step 5:
When dividing 403 by 45, we get 8 with a remainder of 43.
Record the quotient 8 as the next digit in the result. 
Result so far: 1818.0
Deduct 360 from 403 and we're left with 43.
Append the next digit (2) from the dividend to 43 and continue with: 432 / 45

On to step 6:
432 divided by 45 is 9 with a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 18189.0
Subtract 405 from 432 to get 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 45

Let's proceed to step 7:
When dividing 278 by 45, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 181896.0
If we take 270 away from 278, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 45

On to step 8:
45 goes into 86 1 times with a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 1818961.0
Subtracting 45 from 86 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 9:
45 can be fit into 410 9 times, resulting in a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 1818961.9
Subtracting 405 from 410 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
45 can be fit into 50 1 times, resulting in a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1818961.91
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 11:
When dividing 50 by 45, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1818961.911
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 1818961.911, and the remainder is 0.0005.
