Let's divide 70808872 by 856
The aim is to understand the frequency of 856 in 70808872.

On to step 1:
The number 856 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 856

Advancing to step 2:
When dividing 70 by 856, we get 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Grab the next digit (8) from the dividend, add it to 70, then carry on: 708 / 856

Step 3:
The number 856 fits into 708 0 times, leaving a remainder of 708.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 708 leaves us with 708.
Fetch the next digit (0) from the dividend, attach it to 708 and continue: 7080 / 856

On to step 4:
The number 856 fits into 7080 8 times, leaving a remainder of 232.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 6848 from 7080 and we're left with 232.
Grab the next digit (8) from the dividend, add it to 232, then carry on: 2328 / 856

Going ahead to step 5:
If we divide 2328 by 856, we get 2 and a remainder of 616.
Put 2 as the next digit of the answer. 
Result so far: 82.0
If we subtract 1712 from 2328, we get 616.
Bring next digit (8) of the dividend behind the 616 and repeat the process: 6168 / 856

On to step 6:
If we divide 6168 by 856, we get 7 and a remainder of 176.
The next digit of our result is 7. 
Result so far: 827.0
Deduct 5992 from 6168 and we're left with 176.
Take the next digit (7) from the dividend and append it to 176, then repeat: 1767 / 856

On to step 7:
1767 divided by 856 is 2 with a remainder of 55.
Put 2 as the next digit of the answer. 
Result so far: 8272.0
Subtracting 1712 from 1767 leaves us with 55.
Grab the next digit (2) from the dividend, add it to 55, then carry on: 552 / 856

Moving on to step 8:
The number 856 fits into 552 0 times, leaving a remainder of 552.
Put 0 as the next digit of the answer. 
Result so far: 82720.0
If we subtract 0 from 552, we get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Moving on to step 9:
The number 856 fits into 5520 6 times, leaving a remainder of 384.
Use 6 as the next digit of our solution. 
Result so far: 82720.6
Deduct 5136 from 5520 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 10:
856 goes into 3840 4 times with a remainder of 416.
Put 4 as the next digit of the answer. 
Result so far: 82720.64
If we take 3424 away from 3840, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 11:
856 goes into 4160 4 times with a remainder of 736.
Write down 4 as next digit of the result. 
Result so far: 82720.644
Subtract 3424 from 4160 to get 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

The final result is 82720.644 with a remainder of 0.0736.
