We're dividing 661145 by 77 
We want to divide 661145 by 77.

Going ahead to step 1:
6 divided by 77 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 77

Step 2:
66 divided by 77 is 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 77

On to step 3:
The number 77 fits into 661 8 times, leaving a remainder of 45.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 616 from 661 to get 45.
Grab the next digit (1) from the dividend, add it to 45, then carry on: 451 / 77

Going ahead to step 4:
When dividing 451 by 77, we get 5 with a remainder of 66.
The next digit of our result is 5. 
Result so far: 85.0
The remainder is 66 after subtracting 385 from 451.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 77

Advancing to step 5:
664 divided by 77 is 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 858.0
Deduct 616 from 664 and we're left with 48.
Include the next digit (5) from the dividend after 48, then repeat: 485 / 77

Step 6:
If we divide 485 by 77, we get 6 and a remainder of 23.
The number 6 becomes the next digit in our result. 
Result so far: 8586.0
If we subtract 462 from 485, we 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.

Going ahead to step 7:
230 divided by 77 is 2 with a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 8586.2
The remainder is 76 after subtracting 154 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 8:
The number 77 fits into 760 9 times, leaving a remainder of 67.
Write down 9 as next digit of the result. 
Result so far: 8586.29
If we take 693 away from 760, we end up 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.

Going ahead to step 9:
When dividing 670 by 77, we get 8 with a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 8586.298
If we take 616 away from 670, we end up 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.

Moving on to step 10:
540 divided by 77 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 8586.2987
Subtract 539 from 540 to 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.

Advancing to step 11:
77 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 8586.2987
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
When dividing 100 by 77, we get 1 with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 8586.298701
Subtracting 77 from 100 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 13:
When dividing 230 by 77, we get 2 with a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 8586.2987012
Subtract 154 from 230 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 14:
77 goes into 760 9 times with a remainder of 67.
The next digit of our result is 9. 
Result so far: 8586.29870129
If we subtract 693 from 760, 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.

Our division results in 8586.29870129 with a remaining 6.7e-08.
