Let's divide 451224 by 10
Let's see how many times 10 fits into 451224.

Let's proceed to step 1:
The number 10 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 10

Advancing to step 2:
The number 10 fits into 45 4 times, leaving a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 40 from 45 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 10

Let's proceed to step 3:
If we divide 51 by 10, we get 5 and a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Deduct 50 from 51 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 10

Going ahead to step 4:
When dividing 12 by 10, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 451.0
The remainder is 2 after subtracting 10 from 12.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 10

Moving on to step 5:
When dividing 22 by 10, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 4512.0
Subtracting 20 from 22 leaves us with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 10

Let's proceed to step 6:
When dividing 24 by 10, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 45122.0
If we take 20 away from 24, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
10 can be fit into 40 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 45122.4
Subtracting 40 from 40 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
0 divided by 10 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 45122.4
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
10 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 45122.4
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 45122.4 and a remainder of 0.0.
