2748286 ÷ 777 
The aim is to understand the frequency of 777 in 2748286.

Step 1:
777 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 777

Advancing to step 2:
777 can be fit into 27 0 times, resulting in a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 27 to get 27.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 777

Step 3:
If we divide 274 by 777, we get 0 and a remainder of 274.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 274 leaves us with 274.
Include the next digit (8) from the dividend after 274, then repeat: 2748 / 777

On to step 4:
777 can be fit into 2748 3 times, resulting in a remainder of 417.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 2331 from 2748 and we're left with 417.
Grab the next digit (2) from the dividend, add it to 417, then carry on: 4172 / 777

Advancing to step 5:
777 can be fit into 4172 5 times, resulting in a remainder of 287.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we take 3885 away from 4172, we end up with 287.
Fetch the next digit (8) from the dividend, attach it to 287 and continue: 2878 / 777

Going ahead to step 6:
When dividing 2878 by 777, we get 3 with a remainder of 547.
Write down 3 as next digit of the result. 
Result so far: 353.0
If we subtract 2331 from 2878, we get 547.
Append the next digit (6) from the dividend to 547 and continue with: 5476 / 777

Moving on to step 7:
When dividing 5476 by 777, we get 7 with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 3537.0
Subtracting 5439 from 5476 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 8:
777 can be fit into 370 0 times, resulting in a remainder of 370.
Put 0 as the next digit of the answer. 
Result so far: 3537.0
The remainder is 370 after subtracting 0 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 9:
3700 divided by 777 is 4 with a remainder of 592.
Record the quotient 4 as the next digit in the result. 
Result so far: 3537.04
Subtract 3108 from 3700 to get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Advancing to step 10:
777 can be fit into 5920 7 times, resulting in a remainder of 481.
The number 7 becomes the next digit in our result. 
Result so far: 3537.047
If we take 5439 away from 5920, we end up with 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

On to step 11:
When dividing 4810 by 777, we get 6 with a remainder of 148.
Record the quotient 6 as the next digit in the result. 
Result so far: 3537.0476
Deduct 4662 from 4810 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 12:
777 goes into 1480 1 times with a remainder of 703.
The number 1 becomes the next digit in our result. 
Result so far: 3537.04761
If we subtract 777 from 1480, we get 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

Going ahead to step 13:
When dividing 7030 by 777, we get 9 with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 3537.047619
Deduct 6993 from 7030 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 14:
If we divide 370 by 777, we get 0 and a remainder of 370.
Use 0 as the next digit of our solution. 
Result so far: 3537.047619
The remainder is 370 after subtracting 0 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 15:
When dividing 3700 by 777, we get 4 with a remainder of 592.
Write down 4 as next digit of the result. 
Result so far: 3537.04761904
Deduct 3108 from 3700 and we're left with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

The final result is 3537.04761904 with a remainder of 5.92e-07.
