We look at the division of 505189 by 70 
The aim is to understand the frequency of 70 in 505189.

On to step 1:
If we divide 5 by 70, we get 0 and 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.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 70

Step 2:
When dividing 50 by 70, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Fetch the next digit (5) from the dividend, attach it to 50 and continue: 505 / 70

On to step 3:
If we divide 505 by 70, we get 7 and a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 490 from 505 and we're left with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 70

On to step 4:
70 goes into 151 2 times with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 72.0
Subtracting 140 from 151 leaves us with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 70

Going ahead to step 5:
The number 70 fits into 118 1 times, leaving a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 721.0
Subtracting 70 from 118 leaves us with 48.
Append the next digit (9) from the dividend to 48 and continue with: 489 / 70

Going ahead to step 6:
70 can be fit into 489 6 times, resulting in a remainder of 69.
Write down 6 as next digit of the result. 
Result so far: 7216.0
The remainder is 69 after subtracting 420 from 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 7:
The number 70 fits into 690 9 times, leaving a remainder of 60.
Write down 9 as next digit of the result. 
Result so far: 7216.9
Deduct 630 from 690 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.

Moving on to step 8:
70 goes into 600 8 times with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 7216.98
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 9:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 7216.985
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.

Advancing to step 10:
If we divide 500 by 70, we get 7 and a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 7216.9857
Deduct 490 from 500 and we're left 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.

Let's proceed to step 11:
When dividing 100 by 70, we get 1 with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 7216.98571
If we subtract 70 from 100, we 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.

On to step 12:
If we divide 300 by 70, we get 4 and a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 7216.985714
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.

On to step 13:
200 divided by 70 is 2 with a remainder of 60.
The next digit of our result is 2. 
Result so far: 7216.9857142
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.

Step 14:
600 divided by 70 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 7216.98571428
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.

The quotient of the division is 7216.98571428, and the remainder is 4e-08.
