315404 ÷ 70 
The aim is to understand the frequency of 70 in 315404.

Let's proceed to step 1:
3 divided by 70 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 70

Going ahead to step 2:
The number 70 fits into 31 0 times, leaving a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 70

On to step 3:
The number 70 fits into 315 4 times, leaving a remainder of 35.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 280 from 315 and we're left with 35.
Bring next digit (4) of the dividend behind the 35 and repeat the process: 354 / 70

Let's proceed to step 4:
If we divide 354 by 70, we get 5 and a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we take 350 away from 354, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 70

On to step 5:
70 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 450.0
If we subtract 0 from 40, we get 40.
Grab the next digit (4) from the dividend, add it to 40, then carry on: 404 / 70

Step 6:
70 goes into 404 5 times with a remainder of 54.
The number 5 becomes the next digit in our result. 
Result so far: 4505.0
Subtracting 350 from 404 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 7:
If we divide 540 by 70, we get 7 and a remainder of 50.
The next digit of our result is 7. 
Result so far: 4505.7
Deduct 490 from 540 and we're left 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.

Step 8:
When dividing 500 by 70, we get 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 4505.77
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.

The final outcome is 4505.77, with a leftover of 0.01.
