We're dividing 866126 by 77 
Let's see how many times 77 fits into 866126.

On to step 1:
77 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 77

Going ahead to step 2:
When dividing 86 by 77, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 77 from 86, we get 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 77

On to 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
If we take 77 away from 96, we end up with 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 77

On to step 4:
191 divided by 77 is 2 with a remainder of 37.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
If we subtract 154 from 191, we get 37.
Take the next digit (2) from the dividend and append it to 37, then repeat: 372 / 77

Going ahead to step 5:
372 divided by 77 is 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 1124.0
Subtract 308 from 372 to get 64.
Append the next digit (6) from the dividend to 64 and continue with: 646 / 77

Advancing to step 6:
When dividing 646 by 77, we get 8 with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 11248.0
If we take 616 away from 646, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
If we divide 300 by 77, we get 3 and a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 11248.3
The remainder is 69 after subtracting 231 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 8:
When dividing 690 by 77, we get 8 with a remainder of 74.
The next digit of our result is 8. 
Result so far: 11248.38
Deduct 616 from 690 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 9:
740 divided by 77 is 9 with a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 11248.389
Deduct 693 from 740 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 10:
77 goes into 470 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 11248.3896
Deduct 462 from 470 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
80 divided by 77 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 11248.38961
Subtract 77 from 80 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 12:
30 divided by 77 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 11248.38961
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
77 can be fit into 300 3 times, resulting in a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 11248.3896103
If we subtract 231 from 300, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 14:
When dividing 690 by 77, we get 8 with a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 11248.38961038
Subtract 616 from 690 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Our division results in 11248.38961038 with a remaining 7.4e-08.
