831845 ÷ 70 
The aim is to understand the frequency of 70 in 831845.

Let's proceed to step 1:
The number 70 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 70

Advancing to step 2:
If we divide 83 by 70, we get 1 and a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 70 away from 83, we end up with 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 70

Moving on to step 3:
If we divide 131 by 70, we get 1 and a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 61 after subtracting 70 from 131.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 70

Step 4:
When dividing 618 by 70, we get 8 with a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
Subtracting 560 from 618 leaves us with 58.
Include the next digit (4) from the dividend after 58, then repeat: 584 / 70

Advancing to step 5:
If we divide 584 by 70, we get 8 and a remainder of 24.
The next digit of our result is 8. 
Result so far: 1188.0
Subtracting 560 from 584 leaves us with 24.
Fetch the next digit (5) from the dividend, attach it to 24 and continue: 245 / 70

Advancing to step 6:
The number 70 fits into 245 3 times, leaving a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 11883.0
If we take 210 away from 245, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
70 goes into 350 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 11883.5
Subtracting 350 from 350 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 70 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11883.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
When dividing 0 by 70, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11883.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 11883.5 with a remaining 0.0.
