106209 ÷ 70 
The aim is to understand the frequency of 70 in 106209.

On to step 1:
70 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 70

Advancing to step 2:
The number 70 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 70

On to step 3:
70 goes into 106 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 36 after subtracting 70 from 106.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 70

On to step 4:
When dividing 362 by 70, we get 5 with a remainder of 12.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 350 from 362 to get 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 70

Step 5:
70 can be fit into 120 1 times, resulting in a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 151.0
Deduct 70 from 120 and we're left with 50.
Append the next digit (9) from the dividend to 50 and continue with: 509 / 70

Moving on to step 6:
70 can be fit into 509 7 times, resulting in a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 1517.0
Deduct 490 from 509 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
The number 70 fits into 190 2 times, leaving a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 1517.2
Subtract 140 from 190 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
The number 70 fits into 500 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 1517.27
If we subtract 490 from 500, we get 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 9:
When dividing 100 by 70, we get 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 1517.271
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.

Let's proceed to step 10:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 1517.2714
If we take 280 away from 300, we end up with 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 11:
If we divide 200 by 70, we get 2 and a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 1517.27142
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.

Moving on to step 12:
When dividing 600 by 70, we get 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 1517.271428
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.

Going ahead to step 13:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 1517.2714285
If we subtract 350 from 400, we get 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 14:
70 goes into 500 7 times with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 1517.27142857
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.

Our division results in 1517.27142857 with a remaining 1e-08.
