We're dividing 67616446 by 70 
The aim is to understand the frequency of 70 in 67616446.

On to step 1:
70 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 70

Step 2:
67 divided by 70 is 0 with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Grab the next digit (6) from the dividend, add it to 67, then carry on: 676 / 70

Moving on to step 3:
70 can be fit into 676 9 times, resulting in a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 630 from 676 to get 46.
Take the next digit (1) from the dividend and append it to 46, then repeat: 461 / 70

Step 4:
70 can be fit into 461 6 times, resulting in a remainder of 41.
Use 6 as the next digit of our solution. 
Result so far: 96.0
The remainder is 41 after subtracting 420 from 461.
Grab the next digit (6) from the dividend, add it to 41, then carry on: 416 / 70

Step 5:
416 divided by 70 is 5 with a remainder of 66.
Record the quotient 5 as the next digit in the result. 
Result so far: 965.0
If we take 350 away from 416, we end up with 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 70

Let's proceed to step 6:
The number 70 fits into 664 9 times, leaving a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 9659.0
Subtracting 630 from 664 leaves us with 34.
Bring next digit (4) of the dividend behind the 34 and repeat the process: 344 / 70

Advancing to step 7:
If we divide 344 by 70, we get 4 and a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 96594.0
Deduct 280 from 344 and we're left with 64.
Append the next digit (6) from the dividend to 64 and continue with: 646 / 70

Step 8:
646 divided by 70 is 9 with a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 965949.0
If we take 630 away from 646, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
If we divide 160 by 70, we get 2 and a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 965949.2
Subtract 140 from 160 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.

Moving on to step 10:
If we divide 200 by 70, we get 2 and a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 965949.22
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.

The final outcome is 965949.22, with a leftover of 0.06.
