517261 divided by 70 
The aim is to understand the frequency of 70 in 517261.

Going ahead to step 1:
5 divided by 70 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 70

Advancing to step 2:
If we divide 51 by 70, we get 0 and a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Bring next digit (7) of the dividend behind the 51 and repeat the process: 517 / 70

Step 3:
517 divided by 70 is 7 with a remainder of 27.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 490 from 517 leaves us with 27.
Take the next digit (2) from the dividend and append it to 27, then repeat: 272 / 70

Going ahead to step 4:
If we divide 272 by 70, we get 3 and a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
If we subtract 210 from 272, we get 62.
Grab the next digit (6) from the dividend, add it to 62, then carry on: 626 / 70

Advancing to step 5:
70 goes into 626 8 times with a remainder of 66.
The next digit of our result is 8. 
Result so far: 738.0
Subtract 560 from 626 to get 66.
Include the next digit (1) from the dividend after 66, then repeat: 661 / 70

On to step 6:
The number 70 fits into 661 9 times, leaving a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 7389.0
Deduct 630 from 661 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
When dividing 310 by 70, we get 4 with a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 7389.4
The remainder is 30 after subtracting 280 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
70 goes into 300 4 times with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 7389.44
Subtract 280 from 300 to 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.

The final result is 7389.44 with a remainder of 0.02.
