Let's divide 27880917 by 77
We want to divide 27880917 by 77.

On to step 1:
When dividing 2 by 77, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 77

Let's proceed to step 2:
77 can be fit into 27 0 times, resulting in a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 27 leaves us with 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 77

Moving on to step 3:
77 can be fit into 278 3 times, resulting in a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 231 from 278 and we're left with 47.
Fetch the next digit (8) from the dividend, attach it to 47 and continue: 478 / 77

Going ahead to step 4:
When dividing 478 by 77, we get 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
The remainder is 16 after subtracting 462 from 478.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 77

On to step 5:
77 can be fit into 160 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 362.0
If we take 154 away from 160, we end up with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 77

On to step 6:
77 goes into 69 0 times with a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 3620.0
If we take 0 away from 69, we end up with 69.
Bring next digit (1) of the dividend behind the 69 and repeat the process: 691 / 77

Let's proceed to step 7:
The number 77 fits into 691 8 times, leaving a remainder of 75.
The next digit of our result is 8. 
Result so far: 36208.0
Subtract 616 from 691 to get 75.
Include the next digit (7) from the dividend after 75, then repeat: 757 / 77

On to step 8:
77 goes into 757 9 times with a remainder of 64.
Use 9 as the next digit of our solution. 
Result so far: 362089.0
Deduct 693 from 757 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
640 divided by 77 is 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 362089.8
The remainder is 24 after subtracting 616 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
If we divide 240 by 77, we get 3 and a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 362089.83
Subtracting 231 from 240 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
When dividing 90 by 77, we get 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 362089.831
The remainder is 13 after subtracting 77 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 12:
The number 77 fits into 130 1 times, leaving a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 362089.8311
Deduct 77 from 130 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The final outcome is 362089.8311, with a leftover of 0.00053.
