We look at the division of 849372 by 45 
Let's see how many times 45 fits into 849372.

Step 1:
8 divided by 45 is 0 with 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.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 45

Going ahead to step 2:
When dividing 84 by 45, we get 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 45 from 84 and we're left with 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 45

Advancing to step 3:
45 can be fit into 399 8 times, resulting in a remainder of 39.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 360 from 399 to get 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 45

Step 4:
45 goes into 393 8 times with a remainder of 33.
Put 8 as the next digit of the answer. 
Result so far: 188.0
The remainder is 33 after subtracting 360 from 393.
Take the next digit (7) from the dividend and append it to 33, then repeat: 337 / 45

Moving on to step 5:
When dividing 337 by 45, we get 7 with a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 1887.0
Deduct 315 from 337 and we're left with 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 45

Advancing to step 6:
45 goes into 222 4 times with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 18874.0
Subtract 180 from 222 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
The number 45 fits into 420 9 times, leaving a remainder of 15.
The next digit of our result is 9. 
Result so far: 18874.9
Subtracting 405 from 420 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
150 divided by 45 is 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 18874.93
If we take 135 away from 150, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
45 can be fit into 150 3 times, resulting in a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 18874.933
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 18874.933, with a leftover of 0.0015.
