We look at the division of 49400892 by 680 
The aim is to understand the frequency of 680 in 49400892.

Advancing to step 1:
680 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 680

Going ahead to step 2:
680 can be fit into 49 0 times, resulting in a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Include the next digit (4) from the dividend after 49, then repeat: 494 / 680

Step 3:
If we divide 494 by 680, we get 0 and a remainder of 494.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 494 after subtracting 0 from 494.
Bring next digit (0) of the dividend behind the 494 and repeat the process: 4940 / 680

On to step 4:
The number 680 fits into 4940 7 times, leaving a remainder of 180.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 4760 away from 4940, we end up with 180.
Fetch the next digit (0) from the dividend, attach it to 180 and continue: 1800 / 680

Going ahead to step 5:
680 can be fit into 1800 2 times, resulting in a remainder of 440.
Put 2 as the next digit of the answer. 
Result so far: 72.0
The remainder is 440 after subtracting 1360 from 1800.
Include the next digit (8) from the dividend after 440, then repeat: 4408 / 680

Going ahead to step 6:
680 goes into 4408 6 times with a remainder of 328.
The next digit of our result is 6. 
Result so far: 726.0
Subtracting 4080 from 4408 leaves us with 328.
Include the next digit (9) from the dividend after 328, then repeat: 3289 / 680

On to step 7:
3289 divided by 680 is 4 with a remainder of 569.
Put 4 as the next digit of the answer. 
Result so far: 7264.0
Subtracting 2720 from 3289 leaves us with 569.
Bring next digit (2) of the dividend behind the 569 and repeat the process: 5692 / 680

Moving on to step 8:
When dividing 5692 by 680, we get 8 with a remainder of 252.
Use 8 as the next digit of our solution. 
Result so far: 72648.0
Subtracting 5440 from 5692 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 9:
2520 divided by 680 is 3 with a remainder of 480.
Put 3 as the next digit of the answer. 
Result so far: 72648.3
Subtracting 2040 from 2520 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 10:
680 can be fit into 4800 7 times, resulting in a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 72648.37
If we subtract 4760 from 4800, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
The number 680 fits into 400 0 times, leaving a remainder of 400.
The next digit of our result is 0. 
Result so far: 72648.37
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 12:
If we divide 4000 by 680, we get 5 and a remainder of 600.
The next digit of our result is 5. 
Result so far: 72648.3705
Subtract 3400 from 4000 to 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.

Going ahead to step 13:
The number 680 fits into 6000 8 times, leaving a remainder of 560.
Record the quotient 8 as the next digit in the result. 
Result so far: 72648.37058
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.

On to step 14:
680 can be fit into 5600 8 times, resulting in a remainder of 160.
The next digit of our result is 8. 
Result so far: 72648.370588
If we take 5440 away from 5600, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Our division results in 72648.370588 with a remaining 1.6e-05.
