857313 divided by 45 
Let's see how many times 45 fits into 857313.

Going ahead 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
If we subtract 0 from 8, we get 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.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 45 from 85 and we're left with 40.
Append the next digit (7) from the dividend to 40 and continue with: 407 / 45

Let's proceed to step 3:
45 can be fit into 407 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 405 from 407 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 45

Advancing to step 4:
45 goes into 23 0 times with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 190.0
The remainder is 23 after subtracting 0 from 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 45

Going ahead to step 5:
45 goes into 231 5 times with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 1905.0
Deduct 225 from 231 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 45

Step 6:
When dividing 63 by 45, we get 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 19051.0
Deduct 45 from 63 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
When dividing 180 by 45, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 19051.4
Subtracting 180 from 180 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
The number 45 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 19051.4
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
45 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 19051.4
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 19051.4 and a remainder of 0.0.
