172720 divided by 70 
The aim is to understand the frequency of 70 in 172720.

On to step 1:
The number 70 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 70

Step 2:
If we divide 17 by 70, we get 0 and a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 70

Advancing to step 3:
172 divided by 70 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 140 away from 172, we end up with 32.
Fetch the next digit (7) from the dividend, attach it to 32 and continue: 327 / 70

On to step 4:
327 divided by 70 is 4 with a remainder of 47.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtracting 280 from 327 leaves us with 47.
Grab the next digit (2) from the dividend, add it to 47, then carry on: 472 / 70

Let's proceed to step 5:
472 divided by 70 is 6 with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 246.0
If we take 420 away from 472, we end up with 52.
Bring next digit (0) of the dividend behind the 52 and repeat the process: 520 / 70

Advancing to step 6:
When dividing 520 by 70, we get 7 with a remainder of 30.
The next digit of our result is 7. 
Result so far: 2467.0
The remainder is 30 after subtracting 490 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
70 goes into 300 4 times with a remainder of 20.
The next digit of our result is 4. 
Result so far: 2467.4
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.

On to step 8:
When dividing 200 by 70, we get 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 2467.42
Subtract 140 from 200 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
If we divide 600 by 70, we get 8 and a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 2467.428
Subtract 560 from 600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 2467.4285
Subtracting 350 from 400 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
500 divided by 70 is 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 2467.42857
Subtracting 490 from 500 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
If we divide 100 by 70, we get 1 and a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 2467.428571
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
When dividing 300 by 70, we get 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 2467.4285714
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.

Let's proceed to step 14:
70 goes into 200 2 times with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 2467.42857142
The remainder is 60 after subtracting 140 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 2467.42857142 with a remaining 6e-08.
