We divide 279250 by 70
The aim is to understand the frequency of 70 in 279250.

Advancing to step 1:
If we divide 2 by 70, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 70

Let's proceed to step 2:
If we divide 27 by 70, we get 0 and a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Fetch the next digit (9) from the dividend, attach it to 27 and continue: 279 / 70

Moving on to step 3:
The number 70 fits into 279 3 times, leaving a remainder of 69.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 210 from 279 and we're left with 69.
Include the next digit (2) from the dividend after 69, then repeat: 692 / 70

Moving on to step 4:
If we divide 692 by 70, we get 9 and a remainder of 62.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Deduct 630 from 692 and we're left with 62.
Include the next digit (5) from the dividend after 62, then repeat: 625 / 70

Advancing to step 5:
When dividing 625 by 70, we get 8 with a remainder of 65.
The next digit of our result is 8. 
Result so far: 398.0
If we subtract 560 from 625, we get 65.
Bring next digit (0) of the dividend behind the 65 and repeat the process: 650 / 70

Advancing to step 6:
650 divided by 70 is 9 with a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 3989.0
Subtract 630 from 650 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 7:
200 divided by 70 is 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 3989.2
Deduct 140 from 200 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
If we divide 600 by 70, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 3989.28
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.

Advancing to step 9:
The number 70 fits into 400 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 3989.285
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.

On to step 10:
500 divided by 70 is 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 3989.2857
If we take 490 away from 500, we end up 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.

On to step 11:
If we divide 100 by 70, we get 1 and a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 3989.28571
Deduct 70 from 100 and we're left with 30.
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 12:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 3989.285714
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.

Going ahead to step 13:
If we divide 200 by 70, we get 2 and a remainder of 60.
The next digit of our result is 2. 
Result so far: 3989.2857142
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.

On to step 14:
70 goes into 600 8 times with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 3989.28571428
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.

Our division results in 3989.28571428 with a remaining 4e-08.
