We look at the division of 64408630 by 670 
The aim is to understand the frequency of 670 in 64408630.

Let's proceed to step 1:
670 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 670

Going ahead to step 2:
When dividing 64 by 670, we get 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 670

On to step 3:
670 can be fit into 644 0 times, resulting in a remainder of 644.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 644 to get 644.
Take the next digit (0) from the dividend and append it to 644, then repeat: 6440 / 670

Moving on to step 4:
The number 670 fits into 6440 9 times, leaving a remainder of 410.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 6030 from 6440 leaves us with 410.
Include the next digit (8) from the dividend after 410, then repeat: 4108 / 670

Going ahead to step 5:
The number 670 fits into 4108 6 times, leaving a remainder of 88.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
Subtract 4020 from 4108 to get 88.
Append the next digit (6) from the dividend to 88 and continue with: 886 / 670

Advancing to step 6:
670 can be fit into 886 1 times, resulting in a remainder of 216.
Write down 1 as next digit of the result. 
Result so far: 961.0
Subtract 670 from 886 to get 216.
Fetch the next digit (3) from the dividend, attach it to 216 and continue: 2163 / 670

On to step 7:
670 can be fit into 2163 3 times, resulting in a remainder of 153.
Use 3 as the next digit of our solution. 
Result so far: 9613.0
Subtracting 2010 from 2163 leaves us with 153.
Take the next digit (0) from the dividend and append it to 153, then repeat: 1530 / 670

Step 8:
670 can be fit into 1530 2 times, resulting in a remainder of 190.
Record the quotient 2 as the next digit in the result. 
Result so far: 96132.0
If we take 1340 away from 1530, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 9:
When dividing 1900 by 670, we get 2 with a remainder of 560.
The next digit of our result is 2. 
Result so far: 96132.2
Subtracting 1340 from 1900 leaves us 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 10:
5600 divided by 670 is 8 with a remainder of 240.
Write down 8 as next digit of the result. 
Result so far: 96132.28
Subtract 5360 from 5600 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 11:
The number 670 fits into 2400 3 times, leaving a remainder of 390.
Record the quotient 3 as the next digit in the result. 
Result so far: 96132.283
If we subtract 2010 from 2400, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 12:
3900 divided by 670 is 5 with a remainder of 550.
The next digit of our result is 5. 
Result so far: 96132.2835
If we subtract 3350 from 3900, we 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.

Advancing to step 13:
When dividing 5500 by 670, we get 8 with a remainder of 140.
The next digit of our result is 8. 
Result so far: 96132.28358
Subtract 5360 from 5500 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 14:
When dividing 1400 by 670, we get 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 96132.283582
Subtracting 1340 from 1400 leaves us 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.

Let's proceed to step 15:
600 divided by 670 is 0 with a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 96132.283582
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 16:
When dividing 6000 by 670, we get 8 with a remainder of 640.
Write down 8 as next digit of the result. 
Result so far: 96132.28358208
Subtract 5360 from 6000 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

In conclusion, the division gives 96132.28358208 with a balance of 6.4e-07.
