We're dividing 20918389 by 496 
Our goal is to divide 20918389 by 496.

On to step 1:
If we divide 2 by 496, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 496

On to step 2:
496 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 496

Going ahead to step 3:
When dividing 209 by 496, we get 0 with a remainder of 209.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 209 and we're left with 209.
Append the next digit (1) from the dividend to 209 and continue with: 2091 / 496

Advancing to step 4:
If we divide 2091 by 496, we get 4 and a remainder of 107.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 1984 from 2091 to get 107.
Append the next digit (8) from the dividend to 107 and continue with: 1078 / 496

Going ahead to step 5:
When dividing 1078 by 496, we get 2 with a remainder of 86.
The next digit of our result is 2. 
Result so far: 42.0
Subtracting 992 from 1078 leaves us with 86.
Take the next digit (3) from the dividend and append it to 86, then repeat: 863 / 496

Moving on to step 6:
496 goes into 863 1 times with a remainder of 367.
The number 1 becomes the next digit in our result. 
Result so far: 421.0
Subtracting 496 from 863 leaves us with 367.
Append the next digit (8) from the dividend to 367 and continue with: 3678 / 496

Advancing to step 7:
496 goes into 3678 7 times with a remainder of 206.
The next digit of our result is 7. 
Result so far: 4217.0
Deduct 3472 from 3678 and we're left with 206.
Bring next digit (9) of the dividend behind the 206 and repeat the process: 2069 / 496

On to step 8:
496 goes into 2069 4 times with a remainder of 85.
Put 4 as the next digit of the answer. 
Result so far: 42174.0
Subtracting 1984 from 2069 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 9:
If we divide 850 by 496, we get 1 and a remainder of 354.
Record the quotient 1 as the next digit in the result. 
Result so far: 42174.1
If we take 496 away from 850, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Moving on to step 10:
The number 496 fits into 3540 7 times, leaving a remainder of 68.
Record the quotient 7 as the next digit in the result. 
Result so far: 42174.17
Deduct 3472 from 3540 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 11:
The number 496 fits into 680 1 times, leaving a remainder of 184.
The next digit of our result is 1. 
Result so far: 42174.171
Subtracting 496 from 680 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 12:
The number 496 fits into 1840 3 times, leaving a remainder of 352.
Use 3 as the next digit of our solution. 
Result so far: 42174.1713
Deduct 1488 from 1840 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 13:
If we divide 3520 by 496, we get 7 and a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 42174.17137
If we subtract 3472 from 3520, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 14:
480 divided by 496 is 0 with a remainder of 480.
The number 0 becomes the next digit in our result. 
Result so far: 42174.17137
Subtracting 0 from 480 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 15:
When dividing 4800 by 496, we get 9 with a remainder of 336.
Write down 9 as next digit of the result. 
Result so far: 42174.1713709
If we subtract 4464 from 4800, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 16:
496 can be fit into 3360 6 times, resulting in a remainder of 384.
The number 6 becomes the next digit in our result. 
Result so far: 42174.17137096
If we take 2976 away from 3360, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

After the division, we end up with 42174.17137096 and a remainder of 3.84e-07.
