19811 ÷ 77 
We want to divide 19811 by 77.

Moving on to step 1:
The number 77 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 77

On to step 2:
19 divided by 77 is 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 77

Moving on to step 3:
77 can be fit into 198 2 times, resulting in a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 44 after subtracting 154 from 198.
Grab the next digit (1) from the dividend, add it to 44, then carry on: 441 / 77

Let's proceed to step 4:
The number 77 fits into 441 5 times, leaving a remainder of 56.
The next digit of our result is 5. 
Result so far: 25.0
Deduct 385 from 441 and we're left with 56.
Append the next digit (1) from the dividend to 56 and continue with: 561 / 77

On to step 5:
If we divide 561 by 77, we get 7 and a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 257.0
The remainder is 22 after subtracting 539 from 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 6:
If we divide 220 by 77, we get 2 and a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 257.2
If we subtract 154 from 220, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 7:
If we divide 660 by 77, we get 8 and a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 257.28
If we take 616 away from 660, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 8:
The number 77 fits into 440 5 times, leaving a remainder of 55.
The next digit of our result is 5. 
Result so far: 257.285
If we take 385 away from 440, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 9:
77 can be fit into 550 7 times, resulting in a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 257.2857
If we subtract 539 from 550, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 10:
77 can be fit into 110 1 times, resulting in a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 257.28571
Subtracting 77 from 110 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 11:
The number 77 fits into 330 4 times, leaving a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 257.285714
If we subtract 308 from 330, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
77 goes into 220 2 times with a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 257.2857142
Deduct 154 from 220 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 13:
77 goes into 660 8 times with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 257.28571428
If we subtract 616 from 660, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 257.28571428, with a leftover of 4.4e-08.
