We divide 66690785 by 320
The aim is to understand the frequency of 320 in 66690785.

Going ahead to step 1:
The number 320 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 320

On to step 2:
The number 320 fits into 66 0 times, leaving a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Bring next digit (6) of the dividend behind the 66 and repeat the process: 666 / 320

Let's proceed to step 3:
320 goes into 666 2 times with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 640 from 666 and we're left with 26.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 320

Let's proceed to step 4:
269 divided by 320 is 0 with a remainder of 269.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtracting 0 from 269 leaves us with 269.
Include the next digit (0) from the dividend after 269, then repeat: 2690 / 320

Step 5:
The number 320 fits into 2690 8 times, leaving a remainder of 130.
Use 8 as the next digit of our solution. 
Result so far: 208.0
Deduct 2560 from 2690 and we're left with 130.
Include the next digit (7) from the dividend after 130, then repeat: 1307 / 320

Let's proceed to step 6:
1307 divided by 320 is 4 with a remainder of 27.
The next digit of our result is 4. 
Result so far: 2084.0
If we subtract 1280 from 1307, we get 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 320

Moving on to step 7:
The number 320 fits into 278 0 times, leaving a remainder of 278.
Use 0 as the next digit of our solution. 
Result so far: 20840.0
If we subtract 0 from 278, we get 278.
Include the next digit (5) from the dividend after 278, then repeat: 2785 / 320

Let's proceed to step 8:
320 goes into 2785 8 times with a remainder of 225.
Use 8 as the next digit of our solution. 
Result so far: 208408.0
Subtracting 2560 from 2785 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Let's proceed to step 9:
If we divide 2250 by 320, we get 7 and a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 208408.7
Subtract 2240 from 2250 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
320 goes into 100 0 times with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 208408.7
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
If we divide 1000 by 320, we get 3 and a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 208408.703
Subtract 960 from 1000 to 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 12:
320 goes into 400 1 times with a remainder of 80.
The number 1 becomes the next digit in our result. 
Result so far: 208408.7031
The remainder is 80 after subtracting 320 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
320 can be fit into 800 2 times, resulting in a remainder of 160.
Record the quotient 2 as the next digit in the result. 
Result so far: 208408.70312
Deduct 640 from 800 and we're left 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.

Advancing to step 14:
The number 320 fits into 1600 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 208408.703125
Subtracting 1600 from 1600 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 15:
320 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 208408.703125
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 16:
When dividing 0 by 320, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 208408.703125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 208408.703125 and a remainder of 0.0.
