65020561 ÷ 77 
We want to figure out the number of times 65020561 can be divided by 77.

Going ahead to step 1:
The number 77 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 77

On to step 2:
When dividing 65 by 77, we get 0 with a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 65 after subtracting 0 from 65.
Bring next digit (0) of the dividend behind the 65 and repeat the process: 650 / 77

Step 3:
The number 77 fits into 650 8 times, leaving a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 616 from 650 and we're left with 34.
Bring next digit (2) of the dividend behind the 34 and repeat the process: 342 / 77

Step 4:
77 can be fit into 342 4 times, resulting in a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 84.0
Deduct 308 from 342 and we're left with 34.
Include the next digit (0) from the dividend after 34, then repeat: 340 / 77

Moving on to step 5:
77 goes into 340 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 844.0
If we subtract 308 from 340, we get 32.
Take the next digit (5) from the dividend and append it to 32, then repeat: 325 / 77

Step 6:
When dividing 325 by 77, we get 4 with a remainder of 17.
The next digit of our result is 4. 
Result so far: 8444.0
Subtracting 308 from 325 leaves us with 17.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 77

Step 7:
77 goes into 176 2 times with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 84442.0
Subtract 154 from 176 to get 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 77

Going ahead to step 8:
The number 77 fits into 221 2 times, leaving a remainder of 67.
The number 2 becomes the next digit in our result. 
Result so far: 844422.0
Subtracting 154 from 221 leaves us 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.

Advancing to step 9:
When dividing 670 by 77, we get 8 with a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 844422.8
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.

On to step 10:
77 goes into 540 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 844422.87
If we take 539 away from 540, we end up 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.

Going ahead to step 11:
The number 77 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 844422.87
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.

On to step 12:
If we divide 100 by 77, we get 1 and a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 844422.8701
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.

Advancing to step 13:
77 goes into 230 2 times with a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 844422.87012
If we take 154 away from 230, we end up 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.

On to step 14:
77 can be fit into 760 9 times, resulting in a remainder of 67.
Write down 9 as next digit of the result. 
Result so far: 844422.870129
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.

Advancing to step 15:
670 divided by 77 is 8 with a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 844422.8701298
Deduct 616 from 670 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.

Going ahead to step 16:
77 goes into 540 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 844422.87012987
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.

The quotient of the division is 844422.87012987, and the remainder is 1e-09.
