We're dividing 860545 by 77 
We want to divide 860545 by 77.

Advancing to step 1:
8 divided by 77 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 77

Let's proceed to step 2:
86 divided by 77 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
If we take 77 away from 86, we end up with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 77

On to step 3:
77 goes into 90 1 times with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 77 away from 90, we end up with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 77

Moving on to step 4:
The number 77 fits into 135 1 times, leaving a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 111.0
Subtracting 77 from 135 leaves us with 58.
Grab the next digit (4) from the dividend, add it to 58, then carry on: 584 / 77

Advancing to step 5:
584 divided by 77 is 7 with a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 1117.0
The remainder is 45 after subtracting 539 from 584.
Bring next digit (5) of the dividend behind the 45 and repeat the process: 455 / 77

Moving on to step 6:
If we divide 455 by 77, we get 5 and a remainder of 70.
The next digit of our result is 5. 
Result so far: 11175.0
Deduct 385 from 455 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 7:
If we divide 700 by 77, we get 9 and a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 11175.9
Subtract 693 from 700 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
The number 77 fits into 70 0 times, leaving a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 11175.9
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
When dividing 700 by 77, we get 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 11175.909
Subtract 693 from 700 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
70 divided by 77 is 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 11175.909
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 11:
77 can be fit into 700 9 times, resulting in a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 11175.90909
The remainder is 7 after subtracting 693 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
70 divided by 77 is 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 11175.90909
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 13:
700 divided by 77 is 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 11175.9090909
Deduct 693 from 700 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
When dividing 70 by 77, we get 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 11175.9090909
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 11175.9090909 and a remainder of 7e-08.
