878353 divided by 45 
We want to divide 878353 by 45.

Advancing to step 1:
When dividing 8 by 45, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 45

Let's proceed to step 2:
If we divide 87 by 45, we get 1 and a remainder of 42.
The next digit of our result is 1. 
Result so far: 1.0
If we take 45 away from 87, we end up with 42.
Grab the next digit (8) from the dividend, add it to 42, then carry on: 428 / 45

Moving on to step 3:
45 can be fit into 428 9 times, resulting in a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 405 from 428 and we're left with 23.
Grab the next digit (3) from the dividend, add it to 23, then carry on: 233 / 45

Let's proceed to step 4:
45 goes into 233 5 times with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 195.0
If we subtract 225 from 233, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 45

Going ahead to step 5:
45 can be fit into 85 1 times, resulting in a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 1951.0
The remainder is 40 after subtracting 45 from 85.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 45

Step 6:
When dividing 403 by 45, we get 8 with a remainder of 43.
The number 8 becomes the next digit in our result. 
Result so far: 19518.0
The remainder is 43 after subtracting 360 from 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 7:
If we divide 430 by 45, we get 9 and a remainder of 25.
The next digit of our result is 9. 
Result so far: 19518.9
If we take 405 away from 430, we end up 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.

On to step 8:
When dividing 250 by 45, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 19518.95
Deduct 225 from 250 and we're left 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.

Let's proceed to step 9:
45 can be fit into 250 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 19518.955
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 19518.955, and the remainder is 0.0025.
