We look at the division of 42305430 by 499 
Let's see how many times 499 fits into 42305430.

On to step 1:
499 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 499

Moving on to step 2:
The number 499 fits into 42 0 times, leaving a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 499

On to step 3:
When dividing 423 by 499, we get 0 with a remainder of 423.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 423, we get 423.
Take the next digit (0) from the dividend and append it to 423, then repeat: 4230 / 499

Step 4:
The number 499 fits into 4230 8 times, leaving a remainder of 238.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 3992 from 4230 to get 238.
Append the next digit (5) from the dividend to 238 and continue with: 2385 / 499

Going ahead to step 5:
When dividing 2385 by 499, we get 4 with a remainder of 389.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
The remainder is 389 after subtracting 1996 from 2385.
Bring next digit (4) of the dividend behind the 389 and repeat the process: 3894 / 499

Going ahead to step 6:
When dividing 3894 by 499, we get 7 with a remainder of 401.
Write down 7 as next digit of the result. 
Result so far: 847.0
Subtracting 3493 from 3894 leaves us with 401.
Fetch the next digit (3) from the dividend, attach it to 401 and continue: 4013 / 499

Advancing to step 7:
When dividing 4013 by 499, we get 8 with a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 8478.0
Subtract 3992 from 4013 to get 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 499

Step 8:
210 divided by 499 is 0 with a remainder of 210.
The number 0 becomes the next digit in our result. 
Result so far: 84780.0
Deduct 0 from 210 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 9:
499 goes into 2100 4 times with a remainder of 104.
Use 4 as the next digit of our solution. 
Result so far: 84780.4
Subtracting 1996 from 2100 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 10:
499 can be fit into 1040 2 times, resulting in a remainder of 42.
The next digit of our result is 2. 
Result so far: 84780.42
Subtracting 998 from 1040 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
If we divide 420 by 499, we get 0 and a remainder of 420.
The number 0 becomes the next digit in our result. 
Result so far: 84780.42
If we subtract 0 from 420, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 12:
If we divide 4200 by 499, we get 8 and a remainder of 208.
Write down 8 as next digit of the result. 
Result so far: 84780.4208
Subtracting 3992 from 4200 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 13:
2080 divided by 499 is 4 with a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 84780.42084
The remainder is 84 after subtracting 1996 from 2080.
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:
499 goes into 840 1 times with a remainder of 341.
Put 1 as the next digit of the answer. 
Result so far: 84780.420841
Deduct 499 from 840 and we're left with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Advancing to step 15:
3410 divided by 499 is 6 with a remainder of 416.
Use 6 as the next digit of our solution. 
Result so far: 84780.4208416
The remainder is 416 after subtracting 2994 from 3410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 16:
The number 499 fits into 4160 8 times, leaving a remainder of 168.
Record the quotient 8 as the next digit in the result. 
Result so far: 84780.42084168
If we subtract 3992 from 4160, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final outcome is 84780.42084168, with a leftover of 1.68e-07.
