75148487 ÷ 777 
We want to figure out the number of times 75148487 can be divided by 777.

Let's proceed to step 1:
If we divide 7 by 777, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 777

Advancing to step 2:
777 goes into 75 0 times with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Bring next digit (1) of the dividend behind the 75 and repeat the process: 751 / 777

On to step 3:
777 goes into 751 0 times with a remainder of 751.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 751, we end up with 751.
Fetch the next digit (4) from the dividend, attach it to 751 and continue: 7514 / 777

Let's proceed to step 4:
777 goes into 7514 9 times with a remainder of 521.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 6993 away from 7514, we end up with 521.
Include the next digit (8) from the dividend after 521, then repeat: 5218 / 777

Moving on to step 5:
The number 777 fits into 5218 6 times, leaving a remainder of 556.
The next digit of our result is 6. 
Result so far: 96.0
Subtract 4662 from 5218 to get 556.
Take the next digit (4) from the dividend and append it to 556, then repeat: 5564 / 777

Let's proceed to step 6:
777 goes into 5564 7 times with a remainder of 125.
The next digit of our result is 7. 
Result so far: 967.0
Subtracting 5439 from 5564 leaves us with 125.
Bring next digit (8) of the dividend behind the 125 and repeat the process: 1258 / 777

Going ahead to step 7:
When dividing 1258 by 777, we get 1 with a remainder of 481.
The number 1 becomes the next digit in our result. 
Result so far: 9671.0
Deduct 777 from 1258 and we're left with 481.
Take the next digit (7) from the dividend and append it to 481, then repeat: 4817 / 777

Advancing to step 8:
777 can be fit into 4817 6 times, resulting in a remainder of 155.
The number 6 becomes the next digit in our result. 
Result so far: 96716.0
If we subtract 4662 from 4817, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 9:
1550 divided by 777 is 1 with a remainder of 773.
Use 1 as the next digit of our solution. 
Result so far: 96716.1
Subtracting 777 from 1550 leaves us with 773.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7730, and continue the process.

Step 10:
777 can be fit into 7730 9 times, resulting in a remainder of 737.
Use 9 as the next digit of our solution. 
Result so far: 96716.19
Deduct 6993 from 7730 and we're left with 737.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

Let's proceed to step 11:
The number 777 fits into 7370 9 times, leaving a remainder of 377.
Put 9 as the next digit of the answer. 
Result so far: 96716.199
Subtracting 6993 from 7370 leaves us with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

After the division, we end up with 96716.199 and a remainder of 0.0377.
