We look at the division of 648524 by 70 
The aim is to understand the frequency of 70 in 648524.

On to step 1:
70 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 70

Let's proceed to step 2:
64 divided by 70 is 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Include the next digit (8) from the dividend after 64, then repeat: 648 / 70

Step 3:
70 can be fit into 648 9 times, resulting in a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 630 from 648 leaves us with 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 70

Moving on to step 4:
70 goes into 185 2 times with a remainder of 45.
Put 2 as the next digit of the answer. 
Result so far: 92.0
Deduct 140 from 185 and we're left with 45.
Include the next digit (2) from the dividend after 45, then repeat: 452 / 70

Going ahead to step 5:
When dividing 452 by 70, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 926.0
If we take 420 away from 452, we end up with 32.
Include the next digit (4) from the dividend after 32, then repeat: 324 / 70

Moving on to step 6:
70 can be fit into 324 4 times, resulting in a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 9264.0
Subtracting 280 from 324 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
When dividing 440 by 70, we get 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 9264.6
Deduct 420 from 440 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 8:
If we divide 200 by 70, we get 2 and a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 9264.62
If we take 140 away from 200, we end up 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.

Advancing to step 9:
When dividing 600 by 70, we get 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 9264.628
Deduct 560 from 600 and we're left 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.

Going ahead to step 10:
70 goes into 400 5 times with a remainder of 50.
The next digit of our result is 5. 
Result so far: 9264.6285
If we subtract 350 from 400, we 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.

Going ahead to step 11:
70 goes into 500 7 times with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 9264.62857
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.

Advancing to step 12:
100 divided by 70 is 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 9264.628571
Deduct 70 from 100 and we're left 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.

Advancing to step 13:
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: 9264.6285714
If we take 280 away from 300, we end up 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.

On to step 14:
When dividing 200 by 70, we get 2 with a remainder of 60.
The next digit of our result is 2. 
Result so far: 9264.62857142
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.

In conclusion, the division gives 9264.62857142 with a balance of 6e-08.
