Let's divide 12487834 by 77
We want to divide 12487834 by 77.

Going ahead to step 1:
The number 77 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 77

Moving on to step 2:
77 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 77

Step 3:
When dividing 124 by 77, we get 1 with a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 77 from 124 leaves us with 47.
Take the next digit (8) from the dividend and append it to 47, then repeat: 478 / 77

Advancing to step 4:
The number 77 fits into 478 6 times, leaving a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 462 from 478, we get 16.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 77

Going ahead to step 5:
167 divided by 77 is 2 with a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 162.0
The remainder is 13 after subtracting 154 from 167.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 77

Step 6:
If we divide 138 by 77, we get 1 and a remainder of 61.
The next digit of our result is 1. 
Result so far: 1621.0
Deduct 77 from 138 and we're left with 61.
Fetch the next digit (3) from the dividend, attach it to 61 and continue: 613 / 77

On to step 7:
77 can be fit into 613 7 times, resulting in a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 16217.0
The remainder is 74 after subtracting 539 from 613.
Bring next digit (4) of the dividend behind the 74 and repeat the process: 744 / 77

Step 8:
77 goes into 744 9 times with a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 162179.0
Subtracting 693 from 744 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 9:
When dividing 510 by 77, we get 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 162179.6
Deduct 462 from 510 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
When dividing 480 by 77, we get 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 162179.66
If we subtract 462 from 480, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 162179.66 with a remaining 0.018.
