Let's divide 457230 by 99
We want to figure out the number of times 457230 can be divided by 99.

Advancing to step 1:
When dividing 4 by 99, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
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 / 99

On to step 2:
45 divided by 99 is 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Bring next digit (7) of the dividend behind the 45 and repeat the process: 457 / 99

Moving on to step 3:
If we divide 457 by 99, we get 4 and a remainder of 61.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 61 after subtracting 396 from 457.
Take the next digit (2) from the dividend and append it to 61, then repeat: 612 / 99

Going ahead to step 4:
99 goes into 612 6 times with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Deduct 594 from 612 and we're left with 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 99

Let's proceed to step 5:
When dividing 183 by 99, we get 1 with a remainder of 84.
Write down 1 as next digit of the result. 
Result so far: 461.0
Subtract 99 from 183 to get 84.
Fetch the next digit (0) from the dividend, attach it to 84 and continue: 840 / 99

On to step 6:
If we divide 840 by 99, we get 8 and a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 4618.0
If we take 792 away from 840, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 7:
480 divided by 99 is 4 with a remainder of 84.
Use 4 as the next digit of our solution. 
Result so far: 4618.4
Deduct 396 from 480 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 8:
840 divided by 99 is 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 4618.48
If we subtract 792 from 840, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 9:
99 goes into 480 4 times with a remainder of 84.
Write down 4 as next digit of the result. 
Result so far: 4618.484
Deduct 396 from 480 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 10:
If we divide 840 by 99, we get 8 and a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 4618.4848
If we take 792 away from 840, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
The number 99 fits into 480 4 times, leaving a remainder of 84.
Write down 4 as next digit of the result. 
Result so far: 4618.48484
Subtract 396 from 480 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 12:
840 divided by 99 is 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 4618.484848
Subtract 792 from 840 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 13:
If we divide 480 by 99, we get 4 and a remainder of 84.
The next digit of our result is 4. 
Result so far: 4618.4848484
Subtract 396 from 480 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 14:
99 goes into 840 8 times with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 4618.48484848
Subtracting 792 from 840 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 4618.48484848, with a leftover of 4.8e-08.
