666271 ÷ 77 
Our goal is to divide 666271 by 77.

Advancing to step 1:
If we divide 6 by 77, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 77

Let's proceed to step 2:
The number 77 fits into 66 0 times, leaving a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (6) from the dividend and append it to 66, then repeat: 666 / 77

Moving on to step 3:
77 goes into 666 8 times with a remainder of 50.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 616 away from 666, we end up with 50.
Bring next digit (2) of the dividend behind the 50 and repeat the process: 502 / 77

On to step 4:
502 divided by 77 is 6 with a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 86.0
Deduct 462 from 502 and we're left with 40.
Fetch the next digit (7) from the dividend, attach it to 40 and continue: 407 / 77

On to step 5:
If we divide 407 by 77, we get 5 and a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 865.0
Deduct 385 from 407 and we're left with 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 77

Step 6:
The number 77 fits into 221 2 times, leaving a remainder of 67.
Write down 2 as next digit of the result. 
Result so far: 8652.0
If we subtract 154 from 221, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 7:
670 divided by 77 is 8 with a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 8652.8
Subtracting 616 from 670 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 8:
When dividing 540 by 77, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 8652.87
Deduct 539 from 540 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
77 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 8652.87
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
The number 77 fits into 100 1 times, leaving a remainder of 23.
The next digit of our result is 1. 
Result so far: 8652.8701
Subtract 77 from 100 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 11:
When dividing 230 by 77, we get 2 with a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 8652.87012
Deduct 154 from 230 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 12:
77 can be fit into 760 9 times, resulting in a remainder of 67.
Write down 9 as next digit of the result. 
Result so far: 8652.870129
Subtracting 693 from 760 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 13:
77 can be fit into 670 8 times, resulting in a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 8652.8701298
Deduct 616 from 670 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 14:
When dividing 540 by 77, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 8652.87012987
If we subtract 539 from 540, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 8652.87012987, with a leftover of 1e-09.
