Let's divide 815848 by 45
We want to divide 815848 by 45.

Let's proceed to step 1:
If we divide 8 by 45, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 45

On to step 2:
The number 45 fits into 81 1 times, leaving a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 45 from 81 to get 36.
Include the next digit (5) from the dividend after 36, then repeat: 365 / 45

Let's proceed to step 3:
If we divide 365 by 45, we get 8 and a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we subtract 360 from 365, we get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 45

Step 4:
58 divided by 45 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 181.0
If we take 45 away from 58, we end up with 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 45

Step 5:
If we divide 134 by 45, we get 2 and a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 1812.0
Deduct 90 from 134 and we're left with 44.
Grab the next digit (8) from the dividend, add it to 44, then carry on: 448 / 45

Moving on to step 6:
448 divided by 45 is 9 with a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 18129.0
If we take 405 away from 448, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
45 can be fit into 430 9 times, resulting in a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 18129.9
Subtract 405 from 430 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 8:
When dividing 250 by 45, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 18129.95
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
The number 45 fits into 250 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 18129.955
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 18129.955, and the remainder is 0.0025.
