We're dividing 670974 by 70 
The aim is to understand the frequency of 70 in 670974.

Step 1:
The number 70 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 70

Let's proceed to step 2:
70 can be fit into 67 0 times, resulting in a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Take the next digit (0) from the dividend and append it to 67, then repeat: 670 / 70

Step 3:
If we divide 670 by 70, we get 9 and a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 630 from 670 leaves us with 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 70

Step 4:
409 divided by 70 is 5 with a remainder of 59.
Use 5 as the next digit of our solution. 
Result so far: 95.0
The remainder is 59 after subtracting 350 from 409.
Grab the next digit (7) from the dividend, add it to 59, then carry on: 597 / 70

On to step 5:
If we divide 597 by 70, we get 8 and a remainder of 37.
The next digit of our result is 8. 
Result so far: 958.0
Deduct 560 from 597 and we're left with 37.
Append the next digit (4) from the dividend to 37 and continue with: 374 / 70

On to step 6:
The number 70 fits into 374 5 times, leaving a remainder of 24.
Record the quotient 5 as the next digit in the result. 
Result so far: 9585.0
If we take 350 away from 374, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
The number 70 fits into 240 3 times, leaving a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 9585.3
If we take 210 away from 240, we end up 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.

Let's proceed to step 8:
70 goes into 300 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 9585.34
If we take 280 away from 300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 9585.342
Subtracting 140 from 200 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.

Moving on to step 10:
70 goes into 600 8 times with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 9585.3428
If we subtract 560 from 600, we 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.

Step 11:
The number 70 fits into 400 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 9585.34285
Subtract 350 from 400 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
500 divided by 70 is 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 9585.342857
If we take 490 away from 500, we end up with 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 13:
The number 70 fits into 100 1 times, leaving a remainder of 30.
The next digit of our result is 1. 
Result so far: 9585.3428571
If we subtract 70 from 100, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
The number 70 fits into 300 4 times, leaving a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 9585.34285714
If we take 280 away from 300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 9585.34285714, with a leftover of 2e-08.
