77570797 ÷ 684 
The aim is to understand the frequency of 684 in 77570797.

Going ahead to step 1:
The number 684 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 684

Step 2:
684 can be fit into 77 0 times, resulting in a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Fetch the next digit (5) from the dividend, attach it to 77 and continue: 775 / 684

Moving on to step 3:
The number 684 fits into 775 1 times, leaving a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 91 after subtracting 684 from 775.
Include the next digit (7) from the dividend after 91, then repeat: 917 / 684

Advancing to step 4:
If we divide 917 by 684, we get 1 and a remainder of 233.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 684 away from 917, we end up with 233.
Append the next digit (0) from the dividend to 233 and continue with: 2330 / 684

Going ahead to step 5:
If we divide 2330 by 684, we get 3 and a remainder of 278.
The next digit of our result is 3. 
Result so far: 113.0
If we subtract 2052 from 2330, we get 278.
Include the next digit (7) from the dividend after 278, then repeat: 2787 / 684

Going ahead to step 6:
The number 684 fits into 2787 4 times, leaving a remainder of 51.
The next digit of our result is 4. 
Result so far: 1134.0
Subtracting 2736 from 2787 leaves us with 51.
Fetch the next digit (9) from the dividend, attach it to 51 and continue: 519 / 684

Moving on to step 7:
The number 684 fits into 519 0 times, leaving a remainder of 519.
The next digit of our result is 0. 
Result so far: 11340.0
If we take 0 away from 519, we end up with 519.
Append the next digit (7) from the dividend to 519 and continue with: 5197 / 684

Let's proceed to step 8:
684 goes into 5197 7 times with a remainder of 409.
Write down 7 as next digit of the result. 
Result so far: 113407.0
Subtract 4788 from 5197 to get 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Going ahead to step 9:
684 goes into 4090 5 times with a remainder of 670.
Write down 5 as next digit of the result. 
Result so far: 113407.5
Subtracting 3420 from 4090 leaves us with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

On to step 10:
If we divide 6700 by 684, we get 9 and a remainder of 544.
Record the quotient 9 as the next digit in the result. 
Result so far: 113407.59
Subtracting 6156 from 6700 leaves us with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Step 11:
5440 divided by 684 is 7 with a remainder of 652.
Use 7 as the next digit of our solution. 
Result so far: 113407.597
Subtracting 4788 from 5440 leaves us with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Going ahead to step 12:
684 can be fit into 6520 9 times, resulting in a remainder of 364.
Write down 9 as next digit of the result. 
Result so far: 113407.5979
If we take 6156 away from 6520, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 13:
3640 divided by 684 is 5 with a remainder of 220.
Put 5 as the next digit of the answer. 
Result so far: 113407.59795
Deduct 3420 from 3640 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 14:
2200 divided by 684 is 3 with a remainder of 148.
Write down 3 as next digit of the result. 
Result so far: 113407.597953
Subtracting 2052 from 2200 leaves us 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.

Moving on to step 15:
684 can be fit into 1480 2 times, resulting in a remainder of 112.
The number 2 becomes the next digit in our result. 
Result so far: 113407.5979532
Subtract 1368 from 1480 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 16:
The number 684 fits into 1120 1 times, leaving a remainder of 436.
The number 1 becomes the next digit in our result. 
Result so far: 113407.59795321
If we subtract 684 from 1120, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

The final outcome is 113407.59795321, with a leftover of 4.36e-07.
