Let's divide 275423 by 45
We want to divide 275423 by 45.

Advancing to step 1:
45 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 45

Advancing to step 2:
45 can be fit into 27 0 times, resulting in a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 27 leaves us with 27.
Fetch the next digit (5) from the dividend, attach it to 27 and continue: 275 / 45

Advancing to step 3:
275 divided by 45 is 6 with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 5 after subtracting 270 from 275.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 45

Going ahead to step 4:
45 goes into 54 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 61.0
If we take 45 away from 54, we end up with 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 45

Step 5:
45 can be fit into 92 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 612.0
The remainder is 2 after subtracting 90 from 92.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 45

Advancing to step 6:
45 goes into 23 0 times with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 6120.0
Deduct 0 from 23 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
The number 45 fits into 230 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 6120.5
Subtract 225 from 230 to 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.

Step 8:
50 divided by 45 is 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 6120.51
Deduct 45 from 50 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.

Going ahead to step 9:
50 divided by 45 is 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 6120.511
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 final outcome is 6120.511, with a leftover of 0.0005.
