We're dividing 971255 by 77 
Let's see how many times 77 fits into 971255.

Step 1:
77 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 77

Step 2:
If we divide 97 by 77, we get 1 and a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 77 from 97 to get 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 77

Going ahead to step 3:
If we divide 201 by 77, we get 2 and a remainder of 47.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 154 from 201 leaves us with 47.
Fetch the next digit (2) from the dividend, attach it to 47 and continue: 472 / 77

Let's proceed to step 4:
The number 77 fits into 472 6 times, leaving a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Deduct 462 from 472 and we're left with 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 77

Going ahead to step 5:
77 can be fit into 105 1 times, resulting in a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 1261.0
Subtract 77 from 105 to get 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 77

Step 6:
If we divide 285 by 77, we get 3 and a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 12613.0
Deduct 231 from 285 and we're left 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.

Advancing to step 7:
540 divided by 77 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 12613.7
If we subtract 539 from 540, we 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.

Step 8:
When dividing 10 by 77, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 12613.7
Subtracting 0 from 10 leaves us 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.

Going ahead to step 9:
When dividing 100 by 77, we get 1 with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 12613.701
Subtract 77 from 100 to 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.

Step 10:
The number 77 fits into 230 2 times, leaving a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 12613.7012
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.

Step 11:
77 can be fit into 760 9 times, resulting in a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 12613.70129
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.

Let's proceed to step 12:
If we divide 670 by 77, we get 8 and a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 12613.701298
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.

Let's proceed to step 13:
When dividing 540 by 77, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 12613.7012987
Deduct 539 from 540 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 14:
When dividing 10 by 77, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 12613.7012987
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.

The final result is 12613.7012987 with a remainder of 1e-08.
