We look at the division of 64605516 by 70 
The aim is to understand the frequency of 70 in 64605516.

Advancing to step 1:
When dividing 6 by 70, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 70

Step 2:
When dividing 64 by 70, we get 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Fetch the next digit (6) from the dividend, attach it to 64 and continue: 646 / 70

On to step 3:
If we divide 646 by 70, we get 9 and a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 630 from 646 leaves us with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 70

Moving on to step 4:
160 divided by 70 is 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
Deduct 140 from 160 and we're left with 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 70

Moving on to step 5:
70 goes into 205 2 times with a remainder of 65.
Write down 2 as next digit of the result. 
Result so far: 922.0
If we take 140 away from 205, we end up with 65.
Include the next digit (5) from the dividend after 65, then repeat: 655 / 70

Step 6:
70 goes into 655 9 times with a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 9229.0
If we subtract 630 from 655, we get 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 70

Going ahead to step 7:
When dividing 251 by 70, we get 3 with a remainder of 41.
The next digit of our result is 3. 
Result so far: 92293.0
Subtract 210 from 251 to get 41.
Fetch the next digit (6) from the dividend, attach it to 41 and continue: 416 / 70

On to step 8:
When dividing 416 by 70, we get 5 with a remainder of 66.
Write down 5 as next digit of the result. 
Result so far: 922935.0
If we subtract 350 from 416, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 9:
If we divide 660 by 70, we get 9 and a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 922935.9
Subtracting 630 from 660 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.

Advancing to step 10:
If we divide 300 by 70, we get 4 and a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 922935.94
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.

Going ahead to step 11:
70 goes into 200 2 times with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 922935.942
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 12:
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: 922935.9428
If we subtract 560 from 600, we 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.

Moving on to step 13:
If we divide 400 by 70, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 922935.94285
The remainder is 50 after subtracting 350 from 400.
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 14:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 922935.942857
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 15:
70 goes into 100 1 times with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 922935.9428571
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 16:
When dividing 300 by 70, we get 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 922935.94285714
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.

After the division, we end up with 922935.94285714 and a remainder of 2e-08.
