Let's divide 4578928 by 45
Let's see how many times 45 fits into 4578928.

Step 1:
When dividing 4 by 45, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 45

On to step 2:
45 divided by 45 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 45 from 45 and we're left with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 45

Going ahead to step 3:
45 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 45

Let's proceed to step 4:
45 can be fit into 78 1 times, resulting in a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
Subtract 45 from 78 to get 33.
Grab the next digit (9) from the dividend, add it to 33, then carry on: 339 / 45

Advancing to step 5:
If we divide 339 by 45, we get 7 and a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 1017.0
If we take 315 away from 339, we end up with 24.
Grab the next digit (2) from the dividend, add it to 24, then carry on: 242 / 45

Going ahead to step 6:
242 divided by 45 is 5 with a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 10175.0
If we take 225 away from 242, we end up with 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 45

Advancing to step 7:
The number 45 fits into 178 3 times, leaving a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 101753.0
Subtract 135 from 178 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 8:
The number 45 fits into 430 9 times, leaving a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 101753.9
If we subtract 405 from 430, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
250 divided by 45 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 101753.95
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
45 goes into 250 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 101753.955
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 101753.955 and a remainder of 0.0025.
