Let's divide 4564263 by 454
We want to figure out the number of times 4564263 can be divided by 454.

Going ahead to step 1:
If we divide 4 by 454, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 454

Going ahead to step 2:
454 can be fit into 45 0 times, resulting in a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Take the next digit (6) from the dividend and append it to 45, then repeat: 456 / 454

On to step 3:
The number 454 fits into 456 1 times, leaving a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 454 from 456 leaves us with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 454

Step 4:
454 can be fit into 24 0 times, resulting in a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 24 to get 24.
Include the next digit (2) from the dividend after 24, then repeat: 242 / 454

Advancing to step 5:
When dividing 242 by 454, we get 0 with a remainder of 242.
The next digit of our result is 0. 
Result so far: 100.0
The remainder is 242 after subtracting 0 from 242.
Take the next digit (6) from the dividend and append it to 242, then repeat: 2426 / 454

On to step 6:
2426 divided by 454 is 5 with a remainder of 156.
Put 5 as the next digit of the answer. 
Result so far: 1005.0
Subtract 2270 from 2426 to get 156.
Bring next digit (3) of the dividend behind the 156 and repeat the process: 1563 / 454

Advancing to step 7:
1563 divided by 454 is 3 with a remainder of 201.
The number 3 becomes the next digit in our result. 
Result so far: 10053.0
If we take 1362 away from 1563, we end up with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

On to step 8:
The number 454 fits into 2010 4 times, leaving a remainder of 194.
Record the quotient 4 as the next digit in the result. 
Result so far: 10053.4
If we take 1816 away from 2010, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

On to step 9:
454 goes into 1940 4 times with a remainder of 124.
Record the quotient 4 as the next digit in the result. 
Result so far: 10053.44
Deduct 1816 from 1940 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

After the division, we end up with 10053.44 and a remainder of 0.124.
