We're dividing 45173036 by 880 
Our goal is to divide 45173036 by 880.

Step 1:
If we divide 4 by 880, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 880

On to step 2:
880 can be fit into 45 0 times, resulting in a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 880

Advancing to step 3:
451 divided by 880 is 0 with a remainder of 451.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 451 and we're left with 451.
Take the next digit (7) from the dividend and append it to 451, then repeat: 4517 / 880

Going ahead to step 4:
The number 880 fits into 4517 5 times, leaving a remainder of 117.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 4400 from 4517 to get 117.
Grab the next digit (3) from the dividend, add it to 117, then carry on: 1173 / 880

Step 5:
1173 divided by 880 is 1 with a remainder of 293.
The next digit of our result is 1. 
Result so far: 51.0
Deduct 880 from 1173 and we're left with 293.
Bring next digit (0) of the dividend behind the 293 and repeat the process: 2930 / 880

On to step 6:
When dividing 2930 by 880, we get 3 with a remainder of 290.
The number 3 becomes the next digit in our result. 
Result so far: 513.0
Subtract 2640 from 2930 to get 290.
Take the next digit (3) from the dividend and append it to 290, then repeat: 2903 / 880

Step 7:
The number 880 fits into 2903 3 times, leaving a remainder of 263.
Use 3 as the next digit of our solution. 
Result so far: 5133.0
Deduct 2640 from 2903 and we're left with 263.
Fetch the next digit (6) from the dividend, attach it to 263 and continue: 2636 / 880

Going ahead to step 8:
The number 880 fits into 2636 2 times, leaving a remainder of 876.
Write down 2 as next digit of the result. 
Result so far: 51332.0
Subtracting 1760 from 2636 leaves us with 876.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8760, and continue the process.

Step 9:
When dividing 8760 by 880, we get 9 with a remainder of 840.
The number 9 becomes the next digit in our result. 
Result so far: 51332.9
Subtracting 7920 from 8760 leaves us with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Let's proceed to step 10:
The number 880 fits into 8400 9 times, leaving a remainder of 480.
Use 9 as the next digit of our solution. 
Result so far: 51332.99
If we subtract 7920 from 8400, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

After the division, we end up with 51332.99 and a remainder of 0.48.
