We look at the division of 19797819 by 649 
Our goal is to divide 19797819 by 649.

Moving on to step 1:
649 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 649

Advancing to step 2:
When dividing 19 by 649, we get 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 649

Let's proceed to step 3:
649 can be fit into 197 0 times, resulting in a remainder of 197.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 197 and we're left with 197.
Fetch the next digit (9) from the dividend, attach it to 197 and continue: 1979 / 649

Let's proceed to step 4:
The number 649 fits into 1979 3 times, leaving a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 32 after subtracting 1947 from 1979.
Append the next digit (7) from the dividend to 32 and continue with: 327 / 649

Moving on to step 5:
When dividing 327 by 649, we get 0 with a remainder of 327.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtracting 0 from 327 leaves us with 327.
Bring next digit (8) of the dividend behind the 327 and repeat the process: 3278 / 649

On to step 6:
The number 649 fits into 3278 5 times, leaving a remainder of 33.
Put 5 as the next digit of the answer. 
Result so far: 305.0
Subtract 3245 from 3278 to get 33.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 649

Moving on to step 7:
When dividing 331 by 649, we get 0 with a remainder of 331.
Use 0 as the next digit of our solution. 
Result so far: 3050.0
Subtract 0 from 331 to get 331.
Append the next digit (9) from the dividend to 331 and continue with: 3319 / 649

Going ahead to step 8:
3319 divided by 649 is 5 with a remainder of 74.
Put 5 as the next digit of the answer. 
Result so far: 30505.0
The remainder is 74 after subtracting 3245 from 3319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 9:
649 can be fit into 740 1 times, resulting in a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 30505.1
If we subtract 649 from 740, we get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 10:
649 goes into 910 1 times with a remainder of 261.
Put 1 as the next digit of the answer. 
Result so far: 30505.11
Subtracting 649 from 910 leaves us with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

After the division, we end up with 30505.11 and a remainder of 0.261.
