52543081 ÷ 70 
The aim is to understand the frequency of 70 in 52543081.

Advancing to step 1:
5 divided by 70 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 70

Step 2:
If we divide 52 by 70, we get 0 and a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Include the next digit (5) from the dividend after 52, then repeat: 525 / 70

Let's proceed to step 3:
When dividing 525 by 70, we get 7 with a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 490 from 525, we get 35.
Grab the next digit (4) from the dividend, add it to 35, then carry on: 354 / 70

Advancing to step 4:
When dividing 354 by 70, we get 5 with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 75.0
Subtract 350 from 354 to get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 70

Moving on to step 5:
70 can be fit into 43 0 times, resulting in a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 750.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (0) from the dividend, attach it to 43 and continue: 430 / 70

Let's proceed to step 6:
70 can be fit into 430 6 times, resulting in a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 7506.0
Subtracting 420 from 430 leaves us with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 70

Moving on to step 7:
The number 70 fits into 108 1 times, leaving a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 75061.0
Subtracting 70 from 108 leaves us with 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 70

Let's proceed to step 8:
If we divide 381 by 70, we get 5 and a remainder of 31.
The next digit of our result is 5. 
Result so far: 750615.0
If we subtract 350 from 381, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 9:
70 goes into 310 4 times with a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 750615.4
Subtract 280 from 310 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.

Advancing to step 10:
If we divide 300 by 70, we get 4 and a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 750615.44
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.

Our division results in 750615.44 with a remaining 0.02.
