We look at the division of 79343907 by 668 
The aim is to understand the frequency of 668 in 79343907.

Step 1:
The number 668 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 668

Moving on to step 2:
If we divide 79 by 668, we get 0 and a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Append the next digit (3) from the dividend to 79 and continue with: 793 / 668

On to step 3:
The number 668 fits into 793 1 times, leaving a remainder of 125.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 668 from 793 leaves us with 125.
Bring next digit (4) of the dividend behind the 125 and repeat the process: 1254 / 668

Moving on to step 4:
668 can be fit into 1254 1 times, resulting in a remainder of 586.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 668 from 1254 to get 586.
Bring next digit (3) of the dividend behind the 586 and repeat the process: 5863 / 668

Advancing to step 5:
5863 divided by 668 is 8 with a remainder of 519.
Put 8 as the next digit of the answer. 
Result so far: 118.0
The remainder is 519 after subtracting 5344 from 5863.
Bring next digit (9) of the dividend behind the 519 and repeat the process: 5199 / 668

Let's proceed to step 6:
When dividing 5199 by 668, we get 7 with a remainder of 523.
Record the quotient 7 as the next digit in the result. 
Result so far: 1187.0
The remainder is 523 after subtracting 4676 from 5199.
Grab the next digit (0) from the dividend, add it to 523, then carry on: 5230 / 668

Moving on to step 7:
668 can be fit into 5230 7 times, resulting in a remainder of 554.
Put 7 as the next digit of the answer. 
Result so far: 11877.0
The remainder is 554 after subtracting 4676 from 5230.
Bring next digit (7) of the dividend behind the 554 and repeat the process: 5547 / 668

Let's proceed to step 8:
When dividing 5547 by 668, we get 8 with a remainder of 203.
Use 8 as the next digit of our solution. 
Result so far: 118778.0
Subtract 5344 from 5547 to get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Let's proceed to step 9:
2030 divided by 668 is 3 with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 118778.3
Subtracting 2004 from 2030 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
668 goes into 260 0 times with a remainder of 260.
Record the quotient 0 as the next digit in the result. 
Result so far: 118778.3
Subtracting 0 from 260 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 11:
The number 668 fits into 2600 3 times, leaving a remainder of 596.
The number 3 becomes the next digit in our result. 
Result so far: 118778.303
Subtracting 2004 from 2600 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 12:
If we divide 5960 by 668, we get 8 and a remainder of 616.
The next digit of our result is 8. 
Result so far: 118778.3038
If we subtract 5344 from 5960, we get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Going ahead to step 13:
668 can be fit into 6160 9 times, resulting in a remainder of 148.
Put 9 as the next digit of the answer. 
Result so far: 118778.30389
If we subtract 6012 from 6160, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 14:
668 goes into 1480 2 times with a remainder of 144.
Write down 2 as next digit of the result. 
Result so far: 118778.303892
If we subtract 1336 from 1480, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 15:
If we divide 1440 by 668, we get 2 and a remainder of 104.
Write down 2 as next digit of the result. 
Result so far: 118778.3038922
Subtract 1336 from 1440 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

In conclusion, the division gives 118778.3038922 with a balance of 1.04e-06.
