Let's divide 686899 by 70
The aim is to understand the frequency of 70 in 686899.

Going ahead to step 1:
70 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 70

Advancing to step 2:
The number 70 fits into 68 0 times, leaving a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Bring next digit (6) of the dividend behind the 68 and repeat the process: 686 / 70

Going ahead to step 3:
If we divide 686 by 70, we get 9 and a remainder of 56.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 56 after subtracting 630 from 686.
Append the next digit (8) from the dividend to 56 and continue with: 568 / 70

Advancing to step 4:
70 can be fit into 568 8 times, resulting in a remainder of 8.
The next digit of our result is 8. 
Result so far: 98.0
The remainder is 8 after subtracting 560 from 568.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 70

Step 5:
When dividing 89 by 70, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 981.0
Subtracting 70 from 89 leaves us with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 70

Advancing to step 6:
70 can be fit into 199 2 times, resulting in a remainder of 59.
The next digit of our result is 2. 
Result so far: 9812.0
Deduct 140 from 199 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 7:
590 divided by 70 is 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 9812.8
The remainder is 30 after subtracting 560 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
70 goes into 300 4 times with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 9812.84
Subtract 280 from 300 to 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.

On to step 9:
70 goes into 200 2 times with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 9812.842
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.

Moving on to step 10:
70 goes into 600 8 times with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 9812.8428
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
The number 70 fits into 400 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 9812.84285
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.

Moving on to step 12:
If we divide 500 by 70, we get 7 and a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 9812.842857
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.

Step 13:
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: 9812.8428571
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.

Advancing to step 14:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 9812.84285714
If we take 280 away from 300, we end up 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.

Our division results in 9812.84285714 with a remaining 2e-08.
