We look at the division of 359723 by 70 
The aim is to understand the frequency of 70 in 359723.

Going ahead to step 1:
70 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 70

Let's proceed to step 2:
When dividing 35 by 70, we get 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 70

Moving on to step 3:
When dividing 359 by 70, we get 5 with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 350 from 359 leaves us with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 70

Step 4:
When dividing 97 by 70, we get 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 51.0
Deduct 70 from 97 and we're left with 27.
Append the next digit (2) from the dividend to 27 and continue with: 272 / 70

Going ahead to step 5:
The number 70 fits into 272 3 times, leaving a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 513.0
If we subtract 210 from 272, we get 62.
Take the next digit (3) from the dividend and append it to 62, then repeat: 623 / 70

Step 6:
If we divide 623 by 70, we get 8 and a remainder of 63.
Use 8 as the next digit of our solution. 
Result so far: 5138.0
Subtracting 560 from 623 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 7:
When dividing 630 by 70, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 5138.9
The remainder is 0 after subtracting 630 from 630.
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.
Record the quotient 0 as the next digit in the result. 
Result so far: 5138.9
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.

Moving on to step 9:
The number 70 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5138.9
Subtract 0 from 0 to 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.

Our division results in 5138.9 with a remaining 0.0.
