Let's divide 853145 by 45
We're looking to find how many times 45 goes into 853145.

Going ahead to step 1:
If we divide 8 by 45, we get 0 and 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.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 45

Advancing to step 2:
45 goes into 85 1 times with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 45 from 85 and we're left with 40.
Append the next digit (3) from the dividend to 40 and continue with: 403 / 45

Going ahead to step 3:
45 goes into 403 8 times with a remainder of 43.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 360 from 403 and we're left with 43.
Include the next digit (1) from the dividend after 43, then repeat: 431 / 45

Advancing to step 4:
The number 45 fits into 431 9 times, leaving a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 189.0
If we take 405 away from 431, we end up with 26.
Append the next digit (4) from the dividend to 26 and continue with: 264 / 45

Advancing to step 5:
The number 45 fits into 264 5 times, leaving a remainder of 39.
The next digit of our result is 5. 
Result so far: 1895.0
If we subtract 225 from 264, we get 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 45

Advancing to step 6:
45 goes into 395 8 times with a remainder of 35.
The next digit of our result is 8. 
Result so far: 18958.0
The remainder is 35 after subtracting 360 from 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
The number 45 fits into 350 7 times, leaving a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 18958.7
The remainder is 35 after subtracting 315 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 8:
45 can be fit into 350 7 times, resulting in a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 18958.77
The remainder is 35 after subtracting 315 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 18958.77 and a remainder of 0.035.
