45211801 ÷ 499 
We want to figure out the number of times 45211801 can be divided by 499.

Moving on to step 1:
4 divided by 499 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 499

Advancing to step 2:
45 divided by 499 is 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Grab the next digit (2) from the dividend, add it to 45, then carry on: 452 / 499

Step 3:
The number 499 fits into 452 0 times, leaving a remainder of 452.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 452 leaves us with 452.
Bring next digit (1) of the dividend behind the 452 and repeat the process: 4521 / 499

On to step 4:
The number 499 fits into 4521 9 times, leaving a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 4491 away from 4521, we end up with 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 499

Step 5:
499 can be fit into 301 0 times, resulting in a remainder of 301.
The next digit of our result is 0. 
Result so far: 90.0
If we subtract 0 from 301, we get 301.
Fetch the next digit (8) from the dividend, attach it to 301 and continue: 3018 / 499

Going ahead to step 6:
The number 499 fits into 3018 6 times, leaving a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 906.0
Deduct 2994 from 3018 and we're left with 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 499

Going ahead to step 7:
499 goes into 240 0 times with a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 9060.0
Subtract 0 from 240 to get 240.
Grab the next digit (1) from the dividend, add it to 240, then carry on: 2401 / 499

Advancing to step 8:
If we divide 2401 by 499, we get 4 and a remainder of 405.
Record the quotient 4 as the next digit in the result. 
Result so far: 90604.0
Deduct 1996 from 2401 and we're left with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Step 9:
The number 499 fits into 4050 8 times, leaving a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 90604.8
The remainder is 58 after subtracting 3992 from 4050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 10:
If we divide 580 by 499, we get 1 and a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 90604.81
Subtracting 499 from 580 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 11:
499 goes into 810 1 times with a remainder of 311.
Record the quotient 1 as the next digit in the result. 
Result so far: 90604.811
If we take 499 away from 810, we end up with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

The final outcome is 90604.811, with a leftover of 0.0311.
