We're dividing 19780498 by 256 
We want to divide 19780498 by 256.

Step 1:
The number 256 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 256

Let's proceed to step 2:
19 divided by 256 is 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 256

Advancing to step 3:
256 can be fit into 197 0 times, resulting in a remainder of 197.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 197 after subtracting 0 from 197.
Include the next digit (8) from the dividend after 197, then repeat: 1978 / 256

Let's proceed to step 4:
256 can be fit into 1978 7 times, resulting in a remainder of 186.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 1792 away from 1978, we end up with 186.
Append the next digit (0) from the dividend to 186 and continue with: 1860 / 256

On to step 5:
1860 divided by 256 is 7 with a remainder of 68.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
The remainder is 68 after subtracting 1792 from 1860.
Take the next digit (4) from the dividend and append it to 68, then repeat: 684 / 256

Advancing to step 6:
The number 256 fits into 684 2 times, leaving a remainder of 172.
The next digit of our result is 2. 
Result so far: 772.0
Subtracting 512 from 684 leaves us with 172.
Fetch the next digit (9) from the dividend, attach it to 172 and continue: 1729 / 256

On to step 7:
256 goes into 1729 6 times with a remainder of 193.
The number 6 becomes the next digit in our result. 
Result so far: 7726.0
Subtracting 1536 from 1729 leaves us with 193.
Take the next digit (8) from the dividend and append it to 193, then repeat: 1938 / 256

Let's proceed to step 8:
The number 256 fits into 1938 7 times, leaving a remainder of 146.
The number 7 becomes the next digit in our result. 
Result so far: 77267.0
Subtract 1792 from 1938 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 9:
When dividing 1460 by 256, we get 5 with a remainder of 180.
Use 5 as the next digit of our solution. 
Result so far: 77267.5
Deduct 1280 from 1460 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 10:
When dividing 1800 by 256, we get 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 77267.57
Deduct 1792 from 1800 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
256 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 77267.57
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
800 divided by 256 is 3 with a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 77267.5703
Subtract 768 from 800 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
The number 256 fits into 320 1 times, leaving a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 77267.57031
Deduct 256 from 320 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 14:
The number 256 fits into 640 2 times, leaving a remainder of 128.
Put 2 as the next digit of the answer. 
Result so far: 77267.570312
If we take 512 away from 640, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 15:
The number 256 fits into 1280 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 77267.5703125
The remainder is 0 after subtracting 1280 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 16:
256 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 77267.5703125
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 77267.5703125, and the remainder is 0.0.
