79318765 divided by 668 
The aim is to understand the frequency of 668 in 79318765.

Going ahead to step 1:
668 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 668

Let's proceed to step 2:
When dividing 79 by 668, we get 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Grab the next digit (3) from the dividend, add it to 79, then carry on: 793 / 668

Advancing to step 3:
If we divide 793 by 668, we get 1 and a remainder of 125.
The next digit of our result is 1. 
Result so far: 1.0
If we take 668 away from 793, we end up with 125.
Grab the next digit (1) from the dividend, add it to 125, then carry on: 1251 / 668

Let's proceed to step 4:
1251 divided by 668 is 1 with a remainder of 583.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 583 after subtracting 668 from 1251.
Append the next digit (8) from the dividend to 583 and continue with: 5838 / 668

Advancing to step 5:
5838 divided by 668 is 8 with a remainder of 494.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
If we take 5344 away from 5838, we end up with 494.
Take the next digit (7) from the dividend and append it to 494, then repeat: 4947 / 668

Step 6:
668 goes into 4947 7 times with a remainder of 271.
Use 7 as the next digit of our solution. 
Result so far: 1187.0
If we take 4676 away from 4947, we end up with 271.
Append the next digit (6) from the dividend to 271 and continue with: 2716 / 668

Let's proceed to step 7:
If we divide 2716 by 668, we get 4 and a remainder of 44.
The next digit of our result is 4. 
Result so far: 11874.0
Subtracting 2672 from 2716 leaves us with 44.
Include the next digit (5) from the dividend after 44, then repeat: 445 / 668

Step 8:
The number 668 fits into 445 0 times, leaving a remainder of 445.
Record the quotient 0 as the next digit in the result. 
Result so far: 118740.0
If we subtract 0 from 445, we get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Let's proceed to step 9:
When dividing 4450 by 668, we get 6 with a remainder of 442.
The next digit of our result is 6. 
Result so far: 118740.6
If we take 4008 away from 4450, we end up with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

On to step 10:
The number 668 fits into 4420 6 times, leaving a remainder of 412.
Record the quotient 6 as the next digit in the result. 
Result so far: 118740.66
Subtract 4008 from 4420 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

After the division, we end up with 118740.66 and a remainder of 0.412.
