331318 divided by 70 
The aim is to understand the frequency of 70 in 331318.

On to step 1:
70 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 70

On to step 2:
70 can be fit into 33 0 times, resulting in a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Fetch the next digit (1) from the dividend, attach it to 33 and continue: 331 / 70

Advancing to step 3:
The number 70 fits into 331 4 times, leaving a remainder of 51.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 280 from 331 leaves us with 51.
Include the next digit (3) from the dividend after 51, then repeat: 513 / 70

Moving on to step 4:
When dividing 513 by 70, we get 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Deduct 490 from 513 and we're left with 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 70

Step 5:
70 goes into 231 3 times with a remainder of 21.
The next digit of our result is 3. 
Result so far: 473.0
Subtract 210 from 231 to get 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 70

Let's proceed to step 6:
218 divided by 70 is 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 4733.0
If we subtract 210 from 218, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
70 goes into 80 1 times with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 4733.1
If we subtract 70 from 80, 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.

Advancing to step 8:
70 goes into 100 1 times with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 4733.11
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.

After the division, we end up with 4733.11 and a remainder of 0.03.
