We look at the division of 174079 by 70 
The aim is to understand the frequency of 70 in 174079.

Step 1:
70 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 70

Advancing to step 2:
17 divided by 70 is 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 70

Advancing to step 3:
If we divide 174 by 70, we get 2 and a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 140 from 174 and we're left with 34.
Include the next digit (0) from the dividend after 34, then repeat: 340 / 70

On to step 4:
70 can be fit into 340 4 times, resulting in a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Deduct 280 from 340 and we're left with 60.
Include the next digit (7) from the dividend after 60, then repeat: 607 / 70

Going ahead to step 5:
607 divided by 70 is 8 with a remainder of 47.
The next digit of our result is 8. 
Result so far: 248.0
If we take 560 away from 607, we end up with 47.
Grab the next digit (9) from the dividend, add it to 47, then carry on: 479 / 70

Moving on to step 6:
When dividing 479 by 70, we get 6 with a remainder of 59.
The number 6 becomes the next digit in our result. 
Result so far: 2486.0
Subtracting 420 from 479 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 7:
The number 70 fits into 590 8 times, leaving a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 2486.8
Subtract 560 from 590 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 8:
When dividing 300 by 70, we get 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 2486.84
If we subtract 280 from 300, we 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.

On to step 9:
200 divided by 70 is 2 with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 2486.842
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.

Step 10:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 2486.8428
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
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: 2486.84285
If we take 350 away from 400, we end up 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.

On to step 12:
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: 2486.842857
Deduct 490 from 500 and we're left 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.

Moving on to step 13:
If we divide 100 by 70, we get 1 and a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 2486.8428571
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 2486.84285714
If we subtract 280 from 300, we 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.

The final outcome is 2486.84285714, with a leftover of 2e-08.
