12678147 divided by 77 
We're looking to find how many times 77 goes into 12678147.

Step 1:
1 divided by 77 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 77

Let's proceed to step 2:
If we divide 12 by 77, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 77

Let's proceed to step 3:
The number 77 fits into 126 1 times, leaving a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 77 from 126 to get 49.
Fetch the next digit (7) from the dividend, attach it to 49 and continue: 497 / 77

Going ahead to step 4:
77 can be fit into 497 6 times, resulting in a remainder of 35.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 462 from 497 to get 35.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 77

On to step 5:
358 divided by 77 is 4 with a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 164.0
Subtract 308 from 358 to get 50.
Bring next digit (1) of the dividend behind the 50 and repeat the process: 501 / 77

On to step 6:
77 goes into 501 6 times with a remainder of 39.
The next digit of our result is 6. 
Result so far: 1646.0
Subtract 462 from 501 to get 39.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 77

Moving on to step 7:
The number 77 fits into 394 5 times, leaving a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 16465.0
Subtracting 385 from 394 leaves us with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 77

On to step 8:
When dividing 97 by 77, we get 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 164651.0
The remainder is 20 after subtracting 77 from 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
77 goes into 200 2 times with a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 164651.2
Deduct 154 from 200 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
The number 77 fits into 460 5 times, leaving a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 164651.25
If we subtract 385 from 460, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 11:
77 goes into 750 9 times with a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 164651.259
If we subtract 693 from 750, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 12:
570 divided by 77 is 7 with a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 164651.2597
Subtract 539 from 570 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 13:
When dividing 310 by 77, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 164651.25974
If we subtract 308 from 310, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
77 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 164651.25974
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 15:
If we divide 200 by 77, we get 2 and a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 164651.2597402
If we subtract 154 from 200, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 16:
77 goes into 460 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 164651.25974025
Subtract 385 from 460 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The final result is 164651.25974025 with a remainder of 7.5e-08.
