We're dividing 19368817 by 77 
We want to figure out the number of times 19368817 can be divided by 77.

Advancing to step 1:
When dividing 1 by 77, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 77

Step 2:
When dividing 19 by 77, we get 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 77

Moving on to step 3:
77 can be fit into 193 2 times, resulting in a remainder of 39.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 154 from 193 leaves us with 39.
Fetch the next digit (6) from the dividend, attach it to 39 and continue: 396 / 77

Moving on to step 4:
The number 77 fits into 396 5 times, leaving a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we subtract 385 from 396, we get 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 77

Step 5:
77 can be fit into 118 1 times, resulting in a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 251.0
Subtract 77 from 118 to get 41.
Append the next digit (8) from the dividend to 41 and continue with: 418 / 77

On to step 6:
77 can be fit into 418 5 times, resulting in a remainder of 33.
Write down 5 as next digit of the result. 
Result so far: 2515.0
Subtract 385 from 418 to get 33.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 77

Advancing to step 7:
When dividing 331 by 77, we get 4 with a remainder of 23.
Write down 4 as next digit of the result. 
Result so far: 25154.0
Subtract 308 from 331 to get 23.
Bring next digit (7) of the dividend behind the 23 and repeat the process: 237 / 77

Going ahead to step 8:
237 divided by 77 is 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 251543.0
Deduct 231 from 237 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
If we divide 60 by 77, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 251543.0
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
77 goes into 600 7 times with a remainder of 61.
The number 7 becomes the next digit in our result. 
Result so far: 251543.07
Subtracting 539 from 600 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 11:
If we divide 610 by 77, we get 7 and a remainder of 71.
The next digit of our result is 7. 
Result so far: 251543.077
The remainder is 71 after subtracting 539 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The final outcome is 251543.077, with a leftover of 0.0071.
