We're dividing 809660 by 70 
The aim is to understand the frequency of 70 in 809660.

Going ahead to step 1:
70 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 70

Step 2:
70 can be fit into 80 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 70 from 80 to get 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 70

Going ahead to step 3:
When dividing 109 by 70, we get 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 39 after subtracting 70 from 109.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 70

Going ahead to step 4:
70 can be fit into 396 5 times, resulting in a remainder of 46.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
Subtracting 350 from 396 leaves us with 46.
Include the next digit (6) from the dividend after 46, then repeat: 466 / 70

Going ahead to step 5:
466 divided by 70 is 6 with a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 1156.0
Subtracting 420 from 466 leaves us with 46.
Take the next digit (0) from the dividend and append it to 46, then repeat: 460 / 70

Moving on to step 6:
If we divide 460 by 70, we get 6 and a remainder of 40.
The next digit of our result is 6. 
Result so far: 11566.0
Subtract 420 from 460 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.

On to step 7:
If we divide 400 by 70, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 11566.5
Deduct 350 from 400 and we're left 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 8:
70 goes into 500 7 times with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 11566.57
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.

Advancing to step 9:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 11566.571
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.

Going ahead to step 10:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 11566.5714
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.

Step 11:
When dividing 200 by 70, we get 2 with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 11566.57142
If we take 140 away from 200, we end up 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.

Step 12:
600 divided by 70 is 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 11566.571428
If we subtract 560 from 600, we 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.

Going ahead to step 13:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 11566.5714285
The remainder is 50 after subtracting 350 from 400.
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 14:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 11566.57142857
The remainder is 10 after subtracting 490 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 11566.57142857 with a remaining 1e-08.
