We look at the division of 574651 by 45 
Let's see how many times 45 fits into 574651.

Step 1:
When dividing 5 by 45, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 45

Going ahead to step 2:
When dividing 57 by 45, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 45 from 57, we get 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 45

Advancing to step 3:
124 divided by 45 is 2 with a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 34 after subtracting 90 from 124.
Append the next digit (6) from the dividend to 34 and continue with: 346 / 45

Moving on to step 4:
45 can be fit into 346 7 times, resulting in a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 127.0
If we take 315 away from 346, we end up with 31.
Append the next digit (5) from the dividend to 31 and continue with: 315 / 45

Going ahead to step 5:
When dividing 315 by 45, we get 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 1277.0
The remainder is 0 after subtracting 315 from 315.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 45

Going ahead to step 6:
1 divided by 45 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 12770.0
Subtracting 0 from 1 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
The number 45 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 12770.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
If we divide 100 by 45, we get 2 and a remainder of 10.
The next digit of our result is 2. 
Result so far: 12770.02
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
45 can be fit into 100 2 times, resulting in a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 12770.022
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 12770.022 and a remainder of 0.001.
