781671 ÷ 77 
Our goal is to divide 781671 by 77.

On to step 1:
77 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 77

Let's proceed to step 2:
If we divide 78 by 77, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 77 from 78 leaves us with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 77

Advancing to step 3:
When dividing 11 by 77, we get 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 11 after subtracting 0 from 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 77

Moving on to step 4:
If we divide 116 by 77, we get 1 and a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 101.0
If we subtract 77 from 116, we get 39.
Grab the next digit (7) from the dividend, add it to 39, then carry on: 397 / 77

Going ahead to step 5:
If we divide 397 by 77, we get 5 and a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 1015.0
Deduct 385 from 397 and we're left with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 77

Step 6:
The number 77 fits into 121 1 times, leaving a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 10151.0
Deduct 77 from 121 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
The number 77 fits into 440 5 times, leaving a remainder of 55.
The next digit of our result is 5. 
Result so far: 10151.5
If we take 385 away from 440, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 8:
The number 77 fits into 550 7 times, leaving a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 10151.57
If we take 539 away from 550, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
When dividing 110 by 77, we get 1 with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 10151.571
Subtracting 77 from 110 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 10:
77 can be fit into 330 4 times, resulting in a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 10151.5714
If we take 308 away from 330, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 11:
77 can be fit into 220 2 times, resulting in a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 10151.57142
If we take 154 away from 220, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 12:
660 divided by 77 is 8 with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 10151.571428
If we take 616 away from 660, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 13:
When dividing 440 by 77, we get 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 10151.5714285
If we take 385 away from 440, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 14:
When dividing 550 by 77, we get 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 10151.57142857
Subtract 539 from 550 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 10151.57142857, and the remainder is 1.1e-08.
