We divide 815195 by 45
We want to divide 815195 by 45.

Going ahead to step 1:
When dividing 8 by 45, we get 0 with 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

Going ahead to step 2:
When dividing 81 by 45, we get 1 with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 45 away from 81, we end up with 36.
Take the next digit (5) from the dividend and append it to 36, then repeat: 365 / 45

Going ahead to step 3:
365 divided by 45 is 8 with a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtract 360 from 365 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 45

Going ahead to step 4:
45 goes into 51 1 times with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 181.0
Subtracting 45 from 51 leaves us with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 45

Step 5:
When dividing 69 by 45, we get 1 with a remainder of 24.
The next digit of our result is 1. 
Result so far: 1811.0
The remainder is 24 after subtracting 45 from 69.
Include the next digit (5) from the dividend after 24, then repeat: 245 / 45

Advancing to step 6:
When dividing 245 by 45, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 18115.0
Deduct 225 from 245 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
The number 45 fits into 200 4 times, leaving a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 18115.4
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
When dividing 200 by 45, we get 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 18115.44
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 18115.44, with a leftover of 0.02.
