209124 divided by 70 
The aim is to understand the frequency of 70 in 209124.

Step 1:
When dividing 2 by 70, we get 0 with 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.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 70

Step 2:
The number 70 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 70

Advancing to step 3:
70 can be fit into 209 2 times, resulting in a remainder of 69.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 140 from 209 to get 69.
Append the next digit (1) from the dividend to 69 and continue with: 691 / 70

Let's proceed to step 4:
70 goes into 691 9 times with a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtracting 630 from 691 leaves us with 61.
Fetch the next digit (2) from the dividend, attach it to 61 and continue: 612 / 70

Step 5:
612 divided by 70 is 8 with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 298.0
The remainder is 52 after subtracting 560 from 612.
Append the next digit (4) from the dividend to 52 and continue with: 524 / 70

Moving on to step 6:
If we divide 524 by 70, we get 7 and a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 2987.0
Subtracting 490 from 524 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
70 can be fit into 340 4 times, resulting in a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 2987.4
If we take 280 away from 340, we end up 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.

Let's proceed to step 8:
70 goes into 600 8 times with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 2987.48
If we take 560 away from 600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
70 goes into 400 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 2987.485
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.

Moving on to step 10:
70 can be fit into 500 7 times, resulting in a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 2987.4857
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.

Going ahead to step 11:
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: 2987.48571
Subtracting 70 from 100 leaves us 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:
300 divided by 70 is 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 2987.485714
If we subtract 280 from 300, we 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 13:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 2987.4857142
Subtracting 140 from 200 leaves us 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.

Step 14:
70 goes into 600 8 times with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 2987.48571428
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.

The final outcome is 2987.48571428, with a leftover of 4e-08.
