Let's divide 80027591 by 77
We want to figure out the number of times 80027591 can be divided by 77.

Step 1:
When dividing 8 by 77, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 77

Step 2:
The number 77 fits into 80 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 77 from 80 leaves us with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 77

Going ahead to step 3:
If we divide 30 by 77, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 30 after subtracting 0 from 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 77

On to step 4:
77 can be fit into 302 3 times, resulting in a remainder of 71.
The next digit of our result is 3. 
Result so far: 103.0
Subtracting 231 from 302 leaves us with 71.
Take the next digit (7) from the dividend and append it to 71, then repeat: 717 / 77

On to step 5:
The number 77 fits into 717 9 times, leaving a remainder of 24.
Record the quotient 9 as the next digit in the result. 
Result so far: 1039.0
Deduct 693 from 717 and we're left with 24.
Include the next digit (5) from the dividend after 24, then repeat: 245 / 77

Going ahead to step 6:
The number 77 fits into 245 3 times, leaving a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 10393.0
Subtracting 231 from 245 leaves us with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 77

Going ahead to step 7:
149 divided by 77 is 1 with a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 103931.0
Subtract 77 from 149 to get 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 77

Moving on to step 8:
When dividing 721 by 77, we get 9 with a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 1039319.0
If we take 693 away from 721, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
The number 77 fits into 280 3 times, leaving a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 1039319.3
Subtract 231 from 280 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 10:
77 can be fit into 490 6 times, resulting in a remainder of 28.
The next digit of our result is 6. 
Result so far: 1039319.36
Subtract 462 from 490 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
77 can be fit into 280 3 times, resulting in a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 1039319.363
Subtracting 231 from 280 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 12:
490 divided by 77 is 6 with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 1039319.3636
Subtract 462 from 490 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 13:
The number 77 fits into 280 3 times, leaving a remainder of 49.
The next digit of our result is 3. 
Result so far: 1039319.36363
Subtract 231 from 280 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 14:
77 goes into 490 6 times with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 1039319.363636
If we subtract 462 from 490, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 15:
280 divided by 77 is 3 with a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 1039319.3636363
The remainder is 49 after subtracting 231 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 16:
77 goes into 490 6 times with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 1039319.36363636
If we subtract 462 from 490, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 1039319.36363636, and the remainder is 2.8e-08.
