866023 ÷ 77 
We're looking to find how many times 77 goes into 866023.

Advancing to step 1:
When dividing 8 by 77, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 77

Step 2:
If we divide 86 by 77, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 77 from 86 leaves us with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 77

Step 3:
96 divided by 77 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 19 after subtracting 77 from 96.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 77

Let's proceed to step 4:
If we divide 190 by 77, we get 2 and a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 112.0
The remainder is 36 after subtracting 154 from 190.
Grab the next digit (2) from the dividend, add it to 36, then carry on: 362 / 77

Advancing to step 5:
The number 77 fits into 362 4 times, leaving a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 1124.0
Deduct 308 from 362 and we're left with 54.
Fetch the next digit (3) from the dividend, attach it to 54 and continue: 543 / 77

Moving on to step 6:
77 goes into 543 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 11247.0
The remainder is 4 after subtracting 539 from 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
The number 77 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 11247.0
If we subtract 0 from 40, we 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.

Moving on to step 8:
When dividing 400 by 77, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 11247.05
The remainder is 15 after subtracting 385 from 400.
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 9:
The number 77 fits into 150 1 times, leaving a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 11247.051
Deduct 77 from 150 and we're left 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.

On to step 10:
730 divided by 77 is 9 with a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 11247.0519
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.

Moving on to step 11:
77 can be fit into 370 4 times, resulting in a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 11247.05194
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.

Advancing to step 12:
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: 11247.051948
If we take 616 away from 620, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
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: 11247.051948
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
If we divide 400 by 77, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 11247.05194805
Subtracting 385 from 400 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 11247.05194805 with a remaining 1.5e-08.
