We're dividing 865671 by 77 
Our goal is to divide 865671 by 77.

Step 1:
77 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 77

Going ahead to step 2:
86 divided by 77 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 77 from 86 and we're left with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 77

Going ahead to step 3:
The number 77 fits into 95 1 times, leaving a remainder of 18.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 77 from 95, we get 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 77

Step 4:
If we divide 186 by 77, we get 2 and a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
If we take 154 away from 186, we end up with 32.
Bring next digit (7) of the dividend behind the 32 and repeat the process: 327 / 77

On to step 5:
77 can be fit into 327 4 times, resulting in a remainder of 19.
The next digit of our result is 4. 
Result so far: 1124.0
If we take 308 away from 327, we end up with 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 77

Step 6:
The number 77 fits into 191 2 times, leaving a remainder of 37.
The next digit of our result is 2. 
Result so far: 11242.0
Subtracting 154 from 191 leaves us 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.

Moving on to step 7:
77 goes into 370 4 times with a remainder of 62.
The next digit of our result is 4. 
Result so far: 11242.4
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.
Use 8 as the next digit of our solution. 
Result so far: 11242.48
The remainder is 4 after subtracting 616 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
40 divided by 77 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 11242.48
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
77 can be fit into 400 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 11242.4805
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.

Advancing to step 11:
150 divided by 77 is 1 with a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 11242.48051
If we subtract 77 from 150, we get 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 12:
730 divided by 77 is 9 with a remainder of 37.
The next digit of our result is 9. 
Result so far: 11242.480519
Subtract 693 from 730 to 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:
When dividing 370 by 77, we get 4 with a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 11242.4805194
If we subtract 308 from 370, we get 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 14:
If we divide 620 by 77, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 11242.48051948
If we subtract 616 from 620, we 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.

The final outcome is 11242.48051948, with a leftover of 4e-09.
