857561 divided by 45 
Our goal is to divide 857561 by 45.

Going ahead to step 1:
The number 45 fits into 8 0 times, leaving 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.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 45

Let's proceed to step 2:
85 divided by 45 is 1 with a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 45 from 85 to get 40.
Include the next digit (7) from the dividend after 40, then repeat: 407 / 45

Moving on to step 3:
45 goes into 407 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 19.0
If we subtract 405 from 407, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 45

Going ahead to step 4:
When dividing 25 by 45, we get 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 190.0
Subtracting 0 from 25 leaves us with 25.
Grab the next digit (6) from the dividend, add it to 25, then carry on: 256 / 45

Advancing to step 5:
45 goes into 256 5 times with a remainder of 31.
Record the quotient 5 as the next digit in the result. 
Result so far: 1905.0
If we subtract 225 from 256, we get 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 45

Let's proceed to step 6:
If we divide 311 by 45, we get 6 and a remainder of 41.
Write down 6 as next digit of the result. 
Result so far: 19056.0
If we subtract 270 from 311, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
45 can be fit into 410 9 times, resulting in a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 19056.9
Deduct 405 from 410 and we're left 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.

Advancing to step 8:
50 divided by 45 is 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 19056.91
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.

Moving on to step 9:
If we divide 50 by 45, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 19056.911
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 19056.911, and the remainder is 0.0005.
