90489814 ÷ 499 
We're looking to find how many times 499 goes into 90489814.

Let's proceed to step 1:
499 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 499

Advancing to step 2:
90 divided by 499 is 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Append the next digit (4) from the dividend to 90 and continue with: 904 / 499

Step 3:
499 goes into 904 1 times with a remainder of 405.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 499 from 904 to get 405.
Append the next digit (8) from the dividend to 405 and continue with: 4058 / 499

Step 4:
4058 divided by 499 is 8 with a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtract 3992 from 4058 to get 66.
Take the next digit (9) from the dividend and append it to 66, then repeat: 669 / 499

Let's proceed to step 5:
499 goes into 669 1 times with a remainder of 170.
Record the quotient 1 as the next digit in the result. 
Result so far: 181.0
If we subtract 499 from 669, we get 170.
Fetch the next digit (8) from the dividend, attach it to 170 and continue: 1708 / 499

Moving on to step 6:
499 can be fit into 1708 3 times, resulting in a remainder of 211.
The number 3 becomes the next digit in our result. 
Result so far: 1813.0
If we subtract 1497 from 1708, we get 211.
Include the next digit (1) from the dividend after 211, then repeat: 2111 / 499

Moving on to step 7:
When dividing 2111 by 499, we get 4 with a remainder of 115.
Use 4 as the next digit of our solution. 
Result so far: 18134.0
The remainder is 115 after subtracting 1996 from 2111.
Fetch the next digit (4) from the dividend, attach it to 115 and continue: 1154 / 499

On to step 8:
499 can be fit into 1154 2 times, resulting in a remainder of 156.
Put 2 as the next digit of the answer. 
Result so far: 181342.0
Subtract 998 from 1154 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 9:
499 can be fit into 1560 3 times, resulting in a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 181342.3
If we subtract 1497 from 1560, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 10:
If we divide 630 by 499, we get 1 and a remainder of 131.
Use 1 as the next digit of our solution. 
Result so far: 181342.31
Deduct 499 from 630 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 11:
499 goes into 1310 2 times with a remainder of 312.
The number 2 becomes the next digit in our result. 
Result so far: 181342.312
If we take 998 away from 1310, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 12:
When dividing 3120 by 499, we get 6 with a remainder of 126.
Use 6 as the next digit of our solution. 
Result so far: 181342.3126
If we subtract 2994 from 3120, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 13:
The number 499 fits into 1260 2 times, leaving a remainder of 262.
The next digit of our result is 2. 
Result so far: 181342.31262
Subtract 998 from 1260 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Moving on to step 14:
499 can be fit into 2620 5 times, resulting in a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 181342.312625
If we take 2495 away from 2620, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 15:
The number 499 fits into 1250 2 times, leaving a remainder of 252.
Use 2 as the next digit of our solution. 
Result so far: 181342.3126252
If we take 998 away from 1250, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 16:
If we divide 2520 by 499, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 181342.31262525
Subtracting 2495 from 2520 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 181342.31262525, with a leftover of 2.5e-08.
