128781 ÷ 77 
We want to figure out the number of times 128781 can be divided by 77.

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
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 77

Moving on to step 2:
When dividing 12 by 77, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 77

Advancing to step 3:
77 can be fit into 128 1 times, resulting in a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 77 from 128 and we're left with 51.
Append the next digit (7) from the dividend to 51 and continue with: 517 / 77

Advancing to step 4:
The number 77 fits into 517 6 times, leaving a remainder of 55.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 462 from 517 and we're left with 55.
Take the next digit (8) from the dividend and append it to 55, then repeat: 558 / 77

Step 5:
When dividing 558 by 77, we get 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 167.0
The remainder is 19 after subtracting 539 from 558.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 77

On to step 6:
The number 77 fits into 191 2 times, leaving a remainder of 37.
Use 2 as the next digit of our solution. 
Result so far: 1672.0
Deduct 154 from 191 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 7:
If we divide 370 by 77, we get 4 and a remainder of 62.
The next digit of our result is 4. 
Result so far: 1672.4
The remainder is 62 after subtracting 308 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 8:
The number 77 fits into 620 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 1672.48
Subtract 616 from 620 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
If we divide 40 by 77, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 1672.48
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
77 can be fit into 400 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 1672.4805
Subtract 385 from 400 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
The number 77 fits into 150 1 times, leaving a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 1672.48051
If we take 77 away from 150, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 12:
The number 77 fits into 730 9 times, leaving a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 1672.480519
If we subtract 693 from 730, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 13:
77 goes into 370 4 times with a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 1672.4805194
Subtracting 308 from 370 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 14:
The number 77 fits into 620 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 1672.48051948
Subtract 616 from 620 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 1672.48051948 with a remaining 4e-09.
