971585 divided by 77 
We want to figure out the number of times 971585 can be divided by 77.

Step 1:
77 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 77

On to step 2:
97 divided by 77 is 1 with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 77 from 97 leaves us with 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 77

Moving on to step 3:
The number 77 fits into 201 2 times, leaving a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 154 from 201 and we're left with 47.
Append the next digit (5) from the dividend to 47 and continue with: 475 / 77

Advancing to step 4:
77 can be fit into 475 6 times, resulting in a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Subtract 462 from 475 to get 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 77

Step 5:
The number 77 fits into 138 1 times, leaving a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 1261.0
If we take 77 away from 138, we end up with 61.
Grab the next digit (5) from the dividend, add it to 61, then carry on: 615 / 77

On to step 6:
615 divided by 77 is 7 with a remainder of 76.
Put 7 as the next digit of the answer. 
Result so far: 12617.0
Subtracting 539 from 615 leaves us with 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 7:
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: 12617.9
Subtract 693 from 760 to 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.

Let's proceed to step 8:
670 divided by 77 is 8 with a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 12617.98
The remainder is 54 after subtracting 616 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 9:
77 goes into 540 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 12617.987
Subtracting 539 from 540 leaves us 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.

On to step 10:
When dividing 10 by 77, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 12617.987
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
77 can be fit into 100 1 times, resulting in a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 12617.98701
If we take 77 away from 100, we end up 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 12:
77 can be fit into 230 2 times, resulting in a remainder of 76.
The next digit of our result is 2. 
Result so far: 12617.987012
Subtracting 154 from 230 leaves us with 76.
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 13:
77 goes into 760 9 times with a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 12617.9870129
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.

Going ahead to step 14:
77 goes into 670 8 times with a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 12617.98701298
Subtracting 616 from 670 leaves us 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.

After the division, we end up with 12617.98701298 and a remainder of 5.4e-08.
