21458205 divided by 499 
Our goal is to divide 21458205 by 499.

Let's proceed to step 1:
499 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 499

Moving on to step 2:
If we divide 21 by 499, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 499

Moving on to step 3:
If we divide 214 by 499, we get 0 and a remainder of 214.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 214 to get 214.
Grab the next digit (5) from the dividend, add it to 214, then carry on: 2145 / 499

Advancing to step 4:
If we divide 2145 by 499, we get 4 and a remainder of 149.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 1996 from 2145 to get 149.
Grab the next digit (8) from the dividend, add it to 149, then carry on: 1498 / 499

Let's proceed to step 5:
The number 499 fits into 1498 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtract 1497 from 1498 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 499

Step 6:
499 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 430.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 499

Going ahead to step 7:
When dividing 120 by 499, we get 0 with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 4300.0
Deduct 0 from 120 and we're left with 120.
Grab the next digit (5) from the dividend, add it to 120, then carry on: 1205 / 499

On to step 8:
If we divide 1205 by 499, we get 2 and a remainder of 207.
Put 2 as the next digit of the answer. 
Result so far: 43002.0
The remainder is 207 after subtracting 998 from 1205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 9:
2070 divided by 499 is 4 with a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 43002.4
Subtracting 1996 from 2070 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 10:
When dividing 740 by 499, we get 1 with a remainder of 241.
The next digit of our result is 1. 
Result so far: 43002.41
Deduct 499 from 740 and we're left with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

On to step 11:
499 can be fit into 2410 4 times, resulting in a remainder of 414.
The next digit of our result is 4. 
Result so far: 43002.414
Deduct 1996 from 2410 and we're left with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Going ahead to step 12:
If we divide 4140 by 499, we get 8 and a remainder of 148.
Record the quotient 8 as the next digit in the result. 
Result so far: 43002.4148
If we take 3992 away from 4140, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 13:
If we divide 1480 by 499, we get 2 and a remainder of 482.
The number 2 becomes the next digit in our result. 
Result so far: 43002.41482
Subtract 998 from 1480 to get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Step 14:
4820 divided by 499 is 9 with a remainder of 329.
The next digit of our result is 9. 
Result so far: 43002.414829
If we subtract 4491 from 4820, we get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Advancing to step 15:
If we divide 3290 by 499, we get 6 and a remainder of 296.
Put 6 as the next digit of the answer. 
Result so far: 43002.4148296
Subtracting 2994 from 3290 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 16:
When dividing 2960 by 499, we get 5 with a remainder of 465.
Write down 5 as next digit of the result. 
Result so far: 43002.41482965
Subtracting 2495 from 2960 leaves us with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

The final result is 43002.41482965 with a remainder of 4.65e-07.
