We're dividing 667723 by 70 
The aim is to understand the frequency of 70 in 667723.

Step 1:
70 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 70

On to step 2:
70 can be fit into 66 0 times, resulting in a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Take the next digit (7) from the dividend and append it to 66, then repeat: 667 / 70

Let's proceed to step 3:
70 can be fit into 667 9 times, resulting in a remainder of 37.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 630 from 667 to get 37.
Include the next digit (7) from the dividend after 37, then repeat: 377 / 70

Moving on to step 4:
70 goes into 377 5 times with a remainder of 27.
The next digit of our result is 5. 
Result so far: 95.0
Subtracting 350 from 377 leaves us with 27.
Bring next digit (2) of the dividend behind the 27 and repeat the process: 272 / 70

Step 5:
272 divided by 70 is 3 with a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 953.0
Deduct 210 from 272 and we're left with 62.
Grab the next digit (3) from the dividend, add it to 62, then carry on: 623 / 70

Advancing to step 6:
70 goes into 623 8 times with a remainder of 63.
Use 8 as the next digit of our solution. 
Result so far: 9538.0
If we subtract 560 from 623, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 7:
The number 70 fits into 630 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 9538.9
If we subtract 630 from 630, 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.

Step 8:
The number 70 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9538.9
Deduct 0 from 0 and we're left 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.

Advancing to step 9:
70 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9538.9
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.

The final outcome is 9538.9, with a leftover of 0.0.
