93984963 ÷ 680 
The aim is to understand the frequency of 680 in 93984963.

Going ahead to step 1:
680 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 680

Step 2:
680 goes into 93 0 times with a remainder of 93.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 93, we get 93.
Include the next digit (9) from the dividend after 93, then repeat: 939 / 680

Going ahead to step 3:
680 goes into 939 1 times with a remainder of 259.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 680 away from 939, we end up with 259.
Include the next digit (8) from the dividend after 259, then repeat: 2598 / 680

Moving on to step 4:
The number 680 fits into 2598 3 times, leaving a remainder of 558.
The next digit of our result is 3. 
Result so far: 13.0
If we take 2040 away from 2598, we end up with 558.
Fetch the next digit (4) from the dividend, attach it to 558 and continue: 5584 / 680

Moving on to step 5:
5584 divided by 680 is 8 with a remainder of 144.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
If we take 5440 away from 5584, we end up with 144.
Fetch the next digit (9) from the dividend, attach it to 144 and continue: 1449 / 680

Advancing to step 6:
The number 680 fits into 1449 2 times, leaving a remainder of 89.
Record the quotient 2 as the next digit in the result. 
Result so far: 1382.0
Subtracting 1360 from 1449 leaves us with 89.
Take the next digit (6) from the dividend and append it to 89, then repeat: 896 / 680

On to step 7:
When dividing 896 by 680, we get 1 with a remainder of 216.
Use 1 as the next digit of our solution. 
Result so far: 13821.0
The remainder is 216 after subtracting 680 from 896.
Fetch the next digit (3) from the dividend, attach it to 216 and continue: 2163 / 680

On to step 8:
If we divide 2163 by 680, we get 3 and a remainder of 123.
Use 3 as the next digit of our solution. 
Result so far: 138213.0
If we take 2040 away from 2163, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Moving on to step 9:
680 can be fit into 1230 1 times, resulting in a remainder of 550.
The number 1 becomes the next digit in our result. 
Result so far: 138213.1
Subtract 680 from 1230 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 10:
When dividing 5500 by 680, we get 8 with a remainder of 60.
The next digit of our result is 8. 
Result so far: 138213.18
Deduct 5440 from 5500 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
The number 680 fits into 600 0 times, leaving a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 138213.18
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 12:
680 can be fit into 6000 8 times, resulting in a remainder of 560.
The number 8 becomes the next digit in our result. 
Result so far: 138213.1808
Deduct 5440 from 6000 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 13:
680 goes into 5600 8 times with a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 138213.18088
The remainder is 160 after subtracting 5440 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

After the division, we end up with 138213.18088 and a remainder of 0.00016.
