We're dividing 77689864 by 105 
Our goal is to divide 77689864 by 105.

Going ahead to step 1:
7 divided by 105 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 105

On to step 2:
105 can be fit into 77 0 times, resulting in a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Fetch the next digit (6) from the dividend, attach it to 77 and continue: 776 / 105

Advancing to step 3:
105 can be fit into 776 7 times, resulting in a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 735 from 776, we get 41.
Take the next digit (8) from the dividend and append it to 41, then repeat: 418 / 105

Step 4:
If we divide 418 by 105, we get 3 and a remainder of 103.
The next digit of our result is 3. 
Result so far: 73.0
If we take 315 away from 418, we end up with 103.
Append the next digit (9) from the dividend to 103 and continue with: 1039 / 105

Step 5:
When dividing 1039 by 105, we get 9 with a remainder of 94.
The number 9 becomes the next digit in our result. 
Result so far: 739.0
If we subtract 945 from 1039, we get 94.
Include the next digit (8) from the dividend after 94, then repeat: 948 / 105

Advancing to step 6:
The number 105 fits into 948 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 7399.0
Deduct 945 from 948 and we're left with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 105

Step 7:
105 can be fit into 36 0 times, resulting in a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 73990.0
The remainder is 36 after subtracting 0 from 36.
Take the next digit (4) from the dividend and append it to 36, then repeat: 364 / 105

On to step 8:
If we divide 364 by 105, we get 3 and a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 739903.0
Deduct 315 from 364 and we're left 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.

Let's proceed to step 9:
When dividing 490 by 105, we get 4 with a remainder of 70.
The number 4 becomes the next digit in our result. 
Result so far: 739903.4
Subtracting 420 from 490 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
105 goes into 700 6 times with a remainder of 70.
Record the quotient 6 as the next digit in the result. 
Result so far: 739903.46
Subtract 630 from 700 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
The number 105 fits into 700 6 times, leaving a remainder of 70.
Use 6 as the next digit of our solution. 
Result so far: 739903.466
Deduct 630 from 700 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 739903.466, and the remainder is 0.007.
