We're dividing 459689 by 70 
The aim is to understand the frequency of 70 in 459689.

Advancing to step 1:
If we divide 4 by 70, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 70

Let's proceed to step 2:
If we divide 45 by 70, we get 0 and a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Fetch the next digit (9) from the dividend, attach it to 45 and continue: 459 / 70

Advancing to step 3:
When dividing 459 by 70, we get 6 with a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 420 from 459 and we're left with 39.
Take the next digit (6) from the dividend and append it to 39, then repeat: 396 / 70

Step 4:
If we divide 396 by 70, we get 5 and a remainder of 46.
Put 5 as the next digit of the answer. 
Result so far: 65.0
Deduct 350 from 396 and we're left with 46.
Grab the next digit (8) from the dividend, add it to 46, then carry on: 468 / 70

On to step 5:
If we divide 468 by 70, we get 6 and a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 656.0
If we subtract 420 from 468, we get 48.
Bring next digit (9) of the dividend behind the 48 and repeat the process: 489 / 70

Step 6:
70 goes into 489 6 times with a remainder of 69.
Use 6 as the next digit of our solution. 
Result so far: 6566.0
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.

Moving on to step 7:
The number 70 fits into 690 9 times, leaving a remainder of 60.
Record the quotient 9 as the next digit in the result. 
Result so far: 6566.9
Subtracting 630 from 690 leaves us 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 8:
600 divided by 70 is 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 6566.98
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.

Going ahead to step 9:
The number 70 fits into 400 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 6566.985
If we take 350 away from 400, we end up 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.

Moving on to step 10:
The number 70 fits into 500 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 6566.9857
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.

Moving on to step 11:
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: 6566.98571
Subtracting 70 from 100 leaves us 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.

Step 12:
300 divided by 70 is 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 6566.985714
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.

Step 13:
70 goes into 200 2 times with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 6566.9857142
Subtracting 140 from 200 leaves us 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 14:
If we divide 600 by 70, we get 8 and a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 6566.98571428
If we take 560 away from 600, we end up 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.

Our division results in 6566.98571428 with a remaining 4e-08.
