We look at the division of 661482 by 70 
The aim is to understand the frequency of 70 in 661482.

Going ahead to step 1:
The number 70 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 70

Let's proceed to step 2:
If we divide 66 by 70, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 70

Let's proceed to step 3:
If we divide 661 by 70, we get 9 and a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 630 from 661, we get 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 70

Advancing to step 4:
314 divided by 70 is 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 94.0
Subtracting 280 from 314 leaves us with 34.
Include the next digit (8) from the dividend after 34, then repeat: 348 / 70

On to step 5:
The number 70 fits into 348 4 times, leaving a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 944.0
If we take 280 away from 348, we end up with 68.
Bring next digit (2) of the dividend behind the 68 and repeat the process: 682 / 70

Moving on to step 6:
When dividing 682 by 70, we get 9 with a remainder of 52.
The next digit of our result is 9. 
Result so far: 9449.0
Subtract 630 from 682 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 7:
520 divided by 70 is 7 with a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 9449.7
Subtract 490 from 520 to get 30.
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 8:
When dividing 300 by 70, we get 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 9449.74
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
70 goes into 200 2 times with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 9449.742
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.

Advancing to step 10:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 9449.7428
Deduct 560 from 600 and we're left 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.

On to step 11:
When dividing 400 by 70, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 9449.74285
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 12:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 9449.742857
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.

Going ahead to step 13:
70 can be fit into 100 1 times, resulting in a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 9449.7428571
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 14:
The number 70 fits into 300 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 9449.74285714
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.

The final result is 9449.74285714 with a remainder of 2e-08.
