We look at the division of 15188635 by 77 
We want to figure out the number of times 15188635 can be divided by 77.

Advancing to step 1:
When dividing 1 by 77, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 77

Step 2:
If we divide 15 by 77, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 77

Advancing to step 3:
77 can be fit into 151 1 times, resulting in a remainder of 74.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 77 from 151 and we're left with 74.
Include the next digit (8) from the dividend after 74, then repeat: 748 / 77

On to step 4:
When dividing 748 by 77, we get 9 with a remainder of 55.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 693 from 748 to get 55.
Include the next digit (8) from the dividend after 55, then repeat: 558 / 77

Let's proceed to step 5:
When dividing 558 by 77, we get 7 with a remainder of 19.
The next digit of our result is 7. 
Result so far: 197.0
The remainder is 19 after subtracting 539 from 558.
Bring next digit (6) of the dividend behind the 19 and repeat the process: 196 / 77

Step 6:
When dividing 196 by 77, we get 2 with a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 1972.0
Subtracting 154 from 196 leaves us with 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 77

Let's proceed to step 7:
The number 77 fits into 423 5 times, leaving a remainder of 38.
Write down 5 as next digit of the result. 
Result so far: 19725.0
Subtracting 385 from 423 leaves us with 38.
Fetch the next digit (5) from the dividend, attach it to 38 and continue: 385 / 77

Going ahead to step 8:
77 goes into 385 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 197255.0
The remainder is 0 after subtracting 385 from 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
77 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 197255.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
77 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 197255.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 197255.0 with a balance of 0.0.
