Let's divide 820840 by 70
The aim is to understand the frequency of 70 in 820840.

Step 1:
If we divide 8 by 70, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 70

Let's proceed to step 2:
82 divided by 70 is 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
If we take 70 away from 82, we end up with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 70

Advancing to step 3:
If we divide 120 by 70, we get 1 and a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 50 after subtracting 70 from 120.
Take the next digit (8) from the dividend and append it to 50, then repeat: 508 / 70

Advancing to step 4:
If we divide 508 by 70, we get 7 and a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
Subtracting 490 from 508 leaves us with 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 70

Moving on to step 5:
70 goes into 184 2 times with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 1172.0
Subtract 140 from 184 to get 44.
Bring next digit (0) of the dividend behind the 44 and repeat the process: 440 / 70

On to step 6:
When dividing 440 by 70, we get 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 11726.0
Deduct 420 from 440 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.

Going ahead to step 7:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 11726.2
Deduct 140 from 200 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.

Going ahead to step 8:
When dividing 600 by 70, we get 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 11726.28
Deduct 560 from 600 and we're left 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.

Let's proceed to step 9:
If we divide 400 by 70, we get 5 and a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 11726.285
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.

Step 10:
When dividing 500 by 70, we get 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 11726.2857
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.

Let's proceed to step 11:
100 divided by 70 is 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 11726.28571
Deduct 70 from 100 and we're left 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 12:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 11726.285714
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.

Let's proceed to step 13:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 11726.2857142
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:
When dividing 600 by 70, we get 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 11726.28571428
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.

In conclusion, the division gives 11726.28571428 with a balance of 4e-08.
