52536 ÷ 70 
The aim is to understand the frequency of 70 in 52536.

Step 1:
5 divided by 70 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 70

Going ahead to step 2:
If we divide 52 by 70, we get 0 and a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Take the next digit (5) from the dividend and append it to 52, then repeat: 525 / 70

Moving on to step 3:
The number 70 fits into 525 7 times, leaving a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 490 from 525, we get 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 70

Going ahead to step 4:
70 goes into 353 5 times with a remainder of 3.
The next digit of our result is 5. 
Result so far: 75.0
The remainder is 3 after subtracting 350 from 353.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 70

Let's proceed to step 5:
70 can be fit into 36 0 times, resulting in a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 750.0
The remainder is 36 after subtracting 0 from 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 6:
70 goes into 360 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 750.5
If we subtract 350 from 360, 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.

Going ahead to step 7:
70 goes into 100 1 times with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 750.51
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 8:
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: 750.514
Subtracting 280 from 300 leaves us 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.

Going ahead to step 9:
70 can be fit into 200 2 times, resulting in a remainder of 60.
The next digit of our result is 2. 
Result so far: 750.5142
If we subtract 140 from 200, we 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:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 750.51428
If we subtract 560 from 600, we 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.

On to step 11:
When dividing 400 by 70, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 750.514285
The remainder is 50 after subtracting 350 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
When dividing 500 by 70, we get 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 750.5142857
If we take 490 away from 500, we end up 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.

Advancing to step 13:
100 divided by 70 is 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 750.51428571
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.

The final result is 750.51428571 with a remainder of 3e-08.
