We're dividing 77687266 by 634 
We want to divide 77687266 by 634.

Going ahead to step 1:
If we divide 7 by 634, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 634

Let's proceed to step 2:
634 can be fit into 77 0 times, resulting in a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Grab the next digit (6) from the dividend, add it to 77, then carry on: 776 / 634

Step 3:
When dividing 776 by 634, we get 1 with a remainder of 142.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 634 from 776 and we're left with 142.
Include the next digit (8) from the dividend after 142, then repeat: 1428 / 634

On to step 4:
1428 divided by 634 is 2 with a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 160 after subtracting 1268 from 1428.
Fetch the next digit (7) from the dividend, attach it to 160 and continue: 1607 / 634

Let's proceed to step 5:
The number 634 fits into 1607 2 times, leaving a remainder of 339.
Put 2 as the next digit of the answer. 
Result so far: 122.0
Deduct 1268 from 1607 and we're left with 339.
Bring next digit (2) of the dividend behind the 339 and repeat the process: 3392 / 634

Step 6:
When dividing 3392 by 634, we get 5 with a remainder of 222.
Use 5 as the next digit of our solution. 
Result so far: 1225.0
Subtracting 3170 from 3392 leaves us with 222.
Include the next digit (6) from the dividend after 222, then repeat: 2226 / 634

Step 7:
2226 divided by 634 is 3 with a remainder of 324.
Use 3 as the next digit of our solution. 
Result so far: 12253.0
Deduct 1902 from 2226 and we're left with 324.
Take the next digit (6) from the dividend and append it to 324, then repeat: 3246 / 634

Step 8:
When dividing 3246 by 634, we get 5 with a remainder of 76.
Record the quotient 5 as the next digit in the result. 
Result so far: 122535.0
Subtract 3170 from 3246 to get 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 9:
If we divide 760 by 634, we get 1 and a remainder of 126.
Write down 1 as next digit of the result. 
Result so far: 122535.1
Subtract 634 from 760 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 10:
If we divide 1260 by 634, we get 1 and a remainder of 626.
Write down 1 as next digit of the result. 
Result so far: 122535.11
The remainder is 626 after subtracting 634 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

The quotient of the division is 122535.11, and the remainder is 0.626.
