21537900 ÷ 499 
Our goal is to divide 21537900 by 499.

Moving on to step 1:
If we divide 2 by 499, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 499

On to step 2:
If we divide 21 by 499, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 499

Going ahead to step 3:
If we divide 215 by 499, we get 0 and a remainder of 215.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 215 after subtracting 0 from 215.
Grab the next digit (3) from the dividend, add it to 215, then carry on: 2153 / 499

Moving on to step 4:
When dividing 2153 by 499, we get 4 with a remainder of 157.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 1996 from 2153 and we're left with 157.
Append the next digit (7) from the dividend to 157 and continue with: 1577 / 499

Let's proceed to step 5:
The number 499 fits into 1577 3 times, leaving a remainder of 80.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Deduct 1497 from 1577 and we're left with 80.
Include the next digit (9) from the dividend after 80, then repeat: 809 / 499

Moving on to step 6:
The number 499 fits into 809 1 times, leaving a remainder of 310.
Use 1 as the next digit of our solution. 
Result so far: 431.0
If we subtract 499 from 809, we get 310.
Include the next digit (0) from the dividend after 310, then repeat: 3100 / 499

Let's proceed to step 7:
If we divide 3100 by 499, we get 6 and a remainder of 106.
Record the quotient 6 as the next digit in the result. 
Result so far: 4316.0
The remainder is 106 after subtracting 2994 from 3100.
Include the next digit (0) from the dividend after 106, then repeat: 1060 / 499

Let's proceed to step 8:
499 can be fit into 1060 2 times, resulting in a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 43162.0
Deduct 998 from 1060 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 9:
If we divide 620 by 499, we get 1 and a remainder of 121.
The next digit of our result is 1. 
Result so far: 43162.1
If we subtract 499 from 620, we get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Let's proceed to step 10:
The number 499 fits into 1210 2 times, leaving a remainder of 212.
The next digit of our result is 2. 
Result so far: 43162.12
If we take 998 away from 1210, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 11:
The number 499 fits into 2120 4 times, leaving a remainder of 124.
Put 4 as the next digit of the answer. 
Result so far: 43162.124
Deduct 1996 from 2120 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.

Step 12:
1240 divided by 499 is 2 with a remainder of 242.
Record the quotient 2 as the next digit in the result. 
Result so far: 43162.1242
Deduct 998 from 1240 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 13:
When dividing 2420 by 499, we get 4 with a remainder of 424.
Record the quotient 4 as the next digit in the result. 
Result so far: 43162.12424
Subtract 1996 from 2420 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Let's proceed to step 14:
499 can be fit into 4240 8 times, resulting in a remainder of 248.
Record the quotient 8 as the next digit in the result. 
Result so far: 43162.124248
Subtracting 3992 from 4240 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 15:
499 can be fit into 2480 4 times, resulting in a remainder of 484.
The number 4 becomes the next digit in our result. 
Result so far: 43162.1242484
Subtract 1996 from 2480 to get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Step 16:
The number 499 fits into 4840 9 times, leaving a remainder of 349.
Record the quotient 9 as the next digit in the result. 
Result so far: 43162.12424849
Subtracting 4491 from 4840 leaves us with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

The final result is 43162.12424849 with a remainder of 3.49e-07.
