We're dividing 18871151 by 779 
We want to figure out the number of times 18871151 can be divided by 779.

Step 1:
The number 779 fits into 1 0 times, leaving 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.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 779

On to step 2:
779 goes into 18 0 times with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 779

On to step 3:
If we divide 188 by 779, we get 0 and a remainder of 188.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 188 and we're left with 188.
Include the next digit (7) from the dividend after 188, then repeat: 1887 / 779

Moving on to step 4:
When dividing 1887 by 779, we get 2 with a remainder of 329.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 1558 away from 1887, we end up with 329.
Append the next digit (1) from the dividend to 329 and continue with: 3291 / 779

Step 5:
The number 779 fits into 3291 4 times, leaving a remainder of 175.
The next digit of our result is 4. 
Result so far: 24.0
If we subtract 3116 from 3291, we get 175.
Include the next digit (1) from the dividend after 175, then repeat: 1751 / 779

Going ahead to step 6:
779 goes into 1751 2 times with a remainder of 193.
Put 2 as the next digit of the answer. 
Result so far: 242.0
The remainder is 193 after subtracting 1558 from 1751.
Include the next digit (5) from the dividend after 193, then repeat: 1935 / 779

Moving on to step 7:
If we divide 1935 by 779, we get 2 and a remainder of 377.
Write down 2 as next digit of the result. 
Result so far: 2422.0
Deduct 1558 from 1935 and we're left with 377.
Fetch the next digit (1) from the dividend, attach it to 377 and continue: 3771 / 779

Advancing to step 8:
779 goes into 3771 4 times with a remainder of 655.
The number 4 becomes the next digit in our result. 
Result so far: 24224.0
The remainder is 655 after subtracting 3116 from 3771.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Going ahead to step 9:
If we divide 6550 by 779, we get 8 and a remainder of 318.
The next digit of our result is 8. 
Result so far: 24224.8
If we subtract 6232 from 6550, we get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Going ahead to step 10:
779 goes into 3180 4 times with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 24224.84
Subtracting 3116 from 3180 leaves us 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.

Let's proceed to step 11:
The number 779 fits into 640 0 times, leaving a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 24224.84
Subtract 0 from 640 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 12:
When dividing 6400 by 779, we get 8 with a remainder of 168.
Put 8 as the next digit of the answer. 
Result so far: 24224.8408
The remainder is 168 after subtracting 6232 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 13:
1680 divided by 779 is 2 with a remainder of 122.
Use 2 as the next digit of our solution. 
Result so far: 24224.84082
Subtracting 1558 from 1680 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 14:
779 can be fit into 1220 1 times, resulting in a remainder of 441.
Record the quotient 1 as the next digit in the result. 
Result so far: 24224.840821
Deduct 779 from 1220 and we're left with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Moving on to step 15:
The number 779 fits into 4410 5 times, leaving a remainder of 515.
Write down 5 as next digit of the result. 
Result so far: 24224.8408215
Subtracting 3895 from 4410 leaves us with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Step 16:
779 goes into 5150 6 times with a remainder of 476.
The number 6 becomes the next digit in our result. 
Result so far: 24224.84082156
Deduct 4674 from 5150 and we're left with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

The final result is 24224.84082156 with a remainder of 4.76e-07.
