We're dividing 302573 by 70 
The aim is to understand the frequency of 70 in 302573.

Going ahead to step 1:
70 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 70

Going ahead to step 2:
The number 70 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 70

On to step 3:
When dividing 302 by 70, we get 4 with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 280 from 302, we get 22.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 70

Moving on to step 4:
225 divided by 70 is 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Deduct 210 from 225 and we're left with 15.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 70

Moving on to step 5:
70 goes into 157 2 times with a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 432.0
If we take 140 away from 157, we end up with 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 70

Advancing to step 6:
When dividing 173 by 70, we get 2 with a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 4322.0
If we subtract 140 from 173, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
If we divide 330 by 70, we get 4 and a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 4322.4
The remainder is 50 after subtracting 280 from 330.
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 8:
The number 70 fits into 500 7 times, leaving a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 4322.47
If we subtract 490 from 500, we 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.

Going ahead to step 9:
The number 70 fits into 100 1 times, leaving a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 4322.471
Subtracting 70 from 100 leaves us 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 10:
If we divide 300 by 70, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 4322.4714
Deduct 280 from 300 and we're left 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 11:
200 divided by 70 is 2 with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 4322.47142
Subtract 140 from 200 to get 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 12:
70 goes into 600 8 times with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 4322.471428
Subtracting 560 from 600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
400 divided by 70 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 4322.4714285
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.

On to step 14:
If we divide 500 by 70, we get 7 and a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 4322.47142857
Subtract 490 from 500 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.

Our division results in 4322.47142857 with a remaining 1e-08.
