We look at the division of 506187 by 70 
The aim is to understand the frequency of 70 in 506187.

On to step 1:
70 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 70

Let's proceed to step 2:
When dividing 50 by 70, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Bring next digit (6) of the dividend behind the 50 and repeat the process: 506 / 70

On to step 3:
70 goes into 506 7 times with a remainder of 16.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 490 from 506 to get 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 70

Going ahead to step 4:
70 goes into 161 2 times with a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 72.0
If we take 140 away from 161, we end up with 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 70

Moving on to step 5:
When dividing 218 by 70, we get 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 723.0
If we take 210 away from 218, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 70

Moving on to step 6:
The number 70 fits into 87 1 times, leaving a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 7231.0
If we take 70 away from 87, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
70 goes into 170 2 times with a remainder of 30.
The next digit of our result is 2. 
Result so far: 7231.2
If we take 140 away from 170, we end up 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.

Going ahead to step 8:
70 can be fit into 300 4 times, resulting in a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 7231.24
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
When dividing 200 by 70, we get 2 with a remainder of 60.
The next digit of our result is 2. 
Result so far: 7231.242
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.

Going ahead to step 10:
If we divide 600 by 70, we get 8 and a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 7231.2428
Subtract 560 from 600 to 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.

Moving on to step 11:
70 goes into 400 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 7231.24285
Subtracting 350 from 400 leaves us 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:
70 goes into 500 7 times with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 7231.242857
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.

Moving on to step 13:
70 goes into 100 1 times with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 7231.2428571
If we take 70 away from 100, we end up 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.

Going ahead to step 14:
300 divided by 70 is 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 7231.24285714
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 7231.24285714 and a remainder of 2e-08.
