We're dividing 16978075 by 670 
The aim is to understand the frequency of 670 in 16978075.

Let's proceed to step 1:
1 divided by 670 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 670

Moving on to step 2:
16 divided by 670 is 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 670

Advancing to step 3:
670 goes into 169 0 times with a remainder of 169.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 169 and we're left with 169.
Bring next digit (7) of the dividend behind the 169 and repeat the process: 1697 / 670

Step 4:
670 can be fit into 1697 2 times, resulting in a remainder of 357.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1340 from 1697, we get 357.
Fetch the next digit (8) from the dividend, attach it to 357 and continue: 3578 / 670

On to step 5:
3578 divided by 670 is 5 with a remainder of 228.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
The remainder is 228 after subtracting 3350 from 3578.
Bring next digit (0) of the dividend behind the 228 and repeat the process: 2280 / 670

Moving on to step 6:
The number 670 fits into 2280 3 times, leaving a remainder of 270.
The next digit of our result is 3. 
Result so far: 253.0
The remainder is 270 after subtracting 2010 from 2280.
Fetch the next digit (7) from the dividend, attach it to 270 and continue: 2707 / 670

On to step 7:
If we divide 2707 by 670, we get 4 and a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 2534.0
Subtracting 2680 from 2707 leaves us with 27.
Bring next digit (5) of the dividend behind the 27 and repeat the process: 275 / 670

Moving on to step 8:
670 goes into 275 0 times with a remainder of 275.
Use 0 as the next digit of our solution. 
Result so far: 25340.0
Subtract 0 from 275 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 9:
2750 divided by 670 is 4 with a remainder of 70.
Put 4 as the next digit of the answer. 
Result so far: 25340.4
Subtracting 2680 from 2750 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
When dividing 700 by 670, we get 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 25340.41
Deduct 670 from 700 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
300 divided by 670 is 0 with a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 25340.41
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 12:
3000 divided by 670 is 4 with a remainder of 320.
Put 4 as the next digit of the answer. 
Result so far: 25340.4104
If we subtract 2680 from 3000, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 13:
670 goes into 3200 4 times with a remainder of 520.
The number 4 becomes the next digit in our result. 
Result so far: 25340.41044
The remainder is 520 after subtracting 2680 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Our division results in 25340.41044 with a remaining 0.00052.
