3784131 ÷ 777 
Let's see how many times 777 fits into 3784131.

On to step 1:
When dividing 3 by 777, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 777

On to step 2:
The number 777 fits into 37 0 times, leaving a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 777

On to step 3:
When dividing 378 by 777, we get 0 with a remainder of 378.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 378, we end up with 378.
Append the next digit (4) from the dividend to 378 and continue with: 3784 / 777

Moving on to step 4:
When dividing 3784 by 777, we get 4 with a remainder of 676.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 676 after subtracting 3108 from 3784.
Include the next digit (1) from the dividend after 676, then repeat: 6761 / 777

Step 5:
The number 777 fits into 6761 8 times, leaving a remainder of 545.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we take 6216 away from 6761, we end up with 545.
Append the next digit (3) from the dividend to 545 and continue with: 5453 / 777

Step 6:
The number 777 fits into 5453 7 times, leaving a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 487.0
The remainder is 14 after subtracting 5439 from 5453.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 777

On to step 7:
777 goes into 141 0 times with a remainder of 141.
The number 0 becomes the next digit in our result. 
Result so far: 4870.0
Subtracting 0 from 141 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Step 8:
777 can be fit into 1410 1 times, resulting in a remainder of 633.
Put 1 as the next digit of the answer. 
Result so far: 4870.1
If we take 777 away from 1410, we end up with 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

Step 9:
777 goes into 6330 8 times with a remainder of 114.
The number 8 becomes the next digit in our result. 
Result so far: 4870.18
Subtracting 6216 from 6330 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 10:
When dividing 1140 by 777, we get 1 with a remainder of 363.
Record the quotient 1 as the next digit in the result. 
Result so far: 4870.181
Subtract 777 from 1140 to get 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Advancing to step 11:
The number 777 fits into 3630 4 times, leaving a remainder of 522.
The next digit of our result is 4. 
Result so far: 4870.1814
Subtract 3108 from 3630 to get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Step 12:
When dividing 5220 by 777, we get 6 with a remainder of 558.
The number 6 becomes the next digit in our result. 
Result so far: 4870.18146
The remainder is 558 after subtracting 4662 from 5220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Going ahead to step 13:
777 goes into 5580 7 times with a remainder of 141.
The next digit of our result is 7. 
Result so far: 4870.181467
Deduct 5439 from 5580 and we're left with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Moving on to step 14:
777 can be fit into 1410 1 times, resulting in a remainder of 633.
Put 1 as the next digit of the answer. 
Result so far: 4870.1814671
If we subtract 777 from 1410, we get 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

Going ahead to step 15:
The number 777 fits into 6330 8 times, leaving a remainder of 114.
Put 8 as the next digit of the answer. 
Result so far: 4870.18146718
If we subtract 6216 from 6330, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

The final result is 4870.18146718 with a remainder of 1.14e-07.
