We look at the division of 217294 by 70 
The aim is to understand the frequency of 70 in 217294.

On to step 1:
2 divided by 70 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 70

Going ahead to step 2:
70 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 70

Advancing to step 3:
The number 70 fits into 217 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 210 from 217 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 70

Advancing to step 4:
If we divide 72 by 70, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Deduct 70 from 72 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 70

Advancing to step 5:
70 goes into 29 0 times with a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 310.0
The remainder is 29 after subtracting 0 from 29.
Fetch the next digit (4) from the dividend, attach it to 29 and continue: 294 / 70

On to step 6:
294 divided by 70 is 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 3104.0
If we subtract 280 from 294, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
140 divided by 70 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 3104.2
The remainder is 0 after subtracting 140 from 140.
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 8:
If we divide 0 by 70, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3104.2
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:
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: 3104.2
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.

Our division results in 3104.2 with a remaining 0.0.
