528230 ÷ 70 
The aim is to understand the frequency of 70 in 528230.

Going ahead to step 1:
70 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 70

Moving on to step 2:
If we divide 52 by 70, we get 0 and a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Include the next digit (8) from the dividend after 52, then repeat: 528 / 70

On to step 3:
70 goes into 528 7 times with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 490 from 528 leaves us with 38.
Take the next digit (2) from the dividend and append it to 38, then repeat: 382 / 70

Moving on to step 4:
382 divided by 70 is 5 with a remainder of 32.
Write down 5 as next digit of the result. 
Result so far: 75.0
Deduct 350 from 382 and we're left with 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 70

Step 5:
323 divided by 70 is 4 with a remainder of 43.
The number 4 becomes the next digit in our result. 
Result so far: 754.0
The remainder is 43 after subtracting 280 from 323.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 70

Moving on to step 6:
The number 70 fits into 430 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 7546.0
Subtracting 420 from 430 leaves us 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.

Step 7:
When dividing 100 by 70, we get 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 7546.1
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.

Moving on to step 8:
When dividing 300 by 70, we get 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 7546.14
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.

Let's proceed to step 9:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 7546.142
Deduct 140 from 200 and we're left 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.

Let's proceed to step 10:
The number 70 fits into 600 8 times, leaving a remainder of 40.
The next digit of our result is 8. 
Result so far: 7546.1428
Subtracting 560 from 600 leaves us 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.

Moving on to step 11:
When dividing 400 by 70, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 7546.14285
Subtract 350 from 400 to 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 12:
70 goes into 500 7 times with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 7546.142857
Subtract 490 from 500 to 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 13:
If we divide 100 by 70, we get 1 and a remainder of 30.
The next digit of our result is 1. 
Result so far: 7546.1428571
Subtract 70 from 100 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.

Moving on to step 14:
When dividing 300 by 70, we get 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 7546.14285714
Deduct 280 from 300 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.

After the division, we end up with 7546.14285714 and a remainder of 2e-08.
