We're dividing 597191 by 70 
The aim is to understand the frequency of 70 in 597191.

Advancing to step 1:
When dividing 5 by 70, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 70

Going ahead to step 2:
The number 70 fits into 59 0 times, leaving a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 59 leaves us with 59.
Append the next digit (7) from the dividend to 59 and continue with: 597 / 70

Step 3:
70 goes into 597 8 times with a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 560 from 597 to get 37.
Fetch the next digit (1) from the dividend, attach it to 37 and continue: 371 / 70

Going ahead to step 4:
70 can be fit into 371 5 times, resulting in a remainder of 21.
The next digit of our result is 5. 
Result so far: 85.0
Deduct 350 from 371 and we're left with 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 70

Step 5:
The number 70 fits into 219 3 times, leaving a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 853.0
If we subtract 210 from 219, we get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 70

On to step 6:
91 divided by 70 is 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 8531.0
Subtract 70 from 91 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
70 can be fit into 210 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 8531.3
If we subtract 210 from 210, 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.

On to step 8:
70 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 8531.3
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.

Step 9:
When dividing 0 by 70, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8531.3
If we take 0 away from 0, we end up 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.

The final result is 8531.3 with a remainder of 0.0.
