82591400 ÷ 777 
The aim is to understand the frequency of 777 in 82591400.

Going ahead to step 1:
777 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 777

On to step 2:
82 divided by 777 is 0 with a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 82 and we're left with 82.
Append the next digit (5) from the dividend to 82 and continue with: 825 / 777

Advancing to step 3:
If we divide 825 by 777, we get 1 and a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 777 from 825, we get 48.
Bring next digit (9) of the dividend behind the 48 and repeat the process: 489 / 777

On to step 4:
When dividing 489 by 777, we get 0 with a remainder of 489.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 489 leaves us with 489.
Fetch the next digit (1) from the dividend, attach it to 489 and continue: 4891 / 777

Moving on to step 5:
777 can be fit into 4891 6 times, resulting in a remainder of 229.
Use 6 as the next digit of our solution. 
Result so far: 106.0
Deduct 4662 from 4891 and we're left with 229.
Grab the next digit (4) from the dividend, add it to 229, then carry on: 2294 / 777

Moving on to step 6:
When dividing 2294 by 777, we get 2 with a remainder of 740.
The next digit of our result is 2. 
Result so far: 1062.0
Subtract 1554 from 2294 to get 740.
Include the next digit (0) from the dividend after 740, then repeat: 7400 / 777

Step 7:
When dividing 7400 by 777, we get 9 with a remainder of 407.
The next digit of our result is 9. 
Result so far: 10629.0
If we subtract 6993 from 7400, we get 407.
Bring next digit (0) of the dividend behind the 407 and repeat the process: 4070 / 777

Step 8:
777 can be fit into 4070 5 times, resulting in a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 106295.0
Subtracting 3885 from 4070 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Moving on to step 9:
The number 777 fits into 1850 2 times, leaving a remainder of 296.
The number 2 becomes the next digit in our result. 
Result so far: 106295.2
Deduct 1554 from 1850 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 10:
The number 777 fits into 2960 3 times, leaving a remainder of 629.
The number 3 becomes the next digit in our result. 
Result so far: 106295.23
The remainder is 629 after subtracting 2331 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

Going ahead to step 11:
The number 777 fits into 6290 8 times, leaving a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 106295.238
Deduct 6216 from 6290 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 12:
If we divide 740 by 777, we get 0 and a remainder of 740.
The number 0 becomes the next digit in our result. 
Result so far: 106295.238
Subtract 0 from 740 to get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

On to step 13:
When dividing 7400 by 777, we get 9 with a remainder of 407.
Write down 9 as next digit of the result. 
Result so far: 106295.23809
Subtracting 6993 from 7400 leaves us with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Advancing to step 14:
The number 777 fits into 4070 5 times, leaving a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 106295.238095
If we subtract 3885 from 4070, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 15:
777 can be fit into 1850 2 times, resulting in a remainder of 296.
Write down 2 as next digit of the result. 
Result so far: 106295.2380952
If we take 1554 away from 1850, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 16:
2960 divided by 777 is 3 with a remainder of 629.
Record the quotient 3 as the next digit in the result. 
Result so far: 106295.23809523
The remainder is 629 after subtracting 2331 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

After the division, we end up with 106295.23809523 and a remainder of 6.29e-07.
