We look at the division of 398322 by 70 
The aim is to understand the frequency of 70 in 398322.

Moving on to step 1:
If we divide 3 by 70, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 70

Step 2:
If we divide 39 by 70, we get 0 and a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (8) from the dividend, attach it to 39 and continue: 398 / 70

Moving on to step 3:
When dividing 398 by 70, we get 5 with a remainder of 48.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 350 away from 398, we end up with 48.
Append the next digit (3) from the dividend to 48 and continue with: 483 / 70

Moving on to step 4:
When dividing 483 by 70, we get 6 with a remainder of 63.
Put 6 as the next digit of the answer. 
Result so far: 56.0
If we subtract 420 from 483, we get 63.
Append the next digit (2) from the dividend to 63 and continue with: 632 / 70

Advancing to step 5:
If we divide 632 by 70, we get 9 and a remainder of 2.
The next digit of our result is 9. 
Result so far: 569.0
The remainder is 2 after subtracting 630 from 632.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 70

Going ahead to step 6:
70 can be fit into 22 0 times, resulting in a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 5690.0
If we subtract 0 from 22, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
If we divide 220 by 70, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 5690.3
The remainder is 10 after subtracting 210 from 220.
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 8:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 5690.31
Subtract 70 from 100 to 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.

Let's proceed to step 9:
If we divide 300 by 70, we get 4 and a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 5690.314
Subtract 280 from 300 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
200 divided by 70 is 2 with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 5690.3142
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.

Going ahead to step 11:
When dividing 600 by 70, we get 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 5690.31428
Subtract 560 from 600 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.

Moving on to step 12:
If we divide 400 by 70, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 5690.314285
Subtracting 350 from 400 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 13:
500 divided by 70 is 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 5690.3142857
The remainder is 10 after subtracting 490 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
70 goes into 100 1 times with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 5690.31428571
If we take 70 away from 100, 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.

After the division, we end up with 5690.31428571 and a remainder of 3e-08.
