We look at the division of 51979670 by 856 
The aim is to understand the frequency of 856 in 51979670.

Let's proceed to step 1:
856 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 856

Going ahead to step 2:
The number 856 fits into 51 0 times, leaving a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 856

Moving on to step 3:
If we divide 519 by 856, we get 0 and a remainder of 519.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 519, we get 519.
Bring next digit (7) of the dividend behind the 519 and repeat the process: 5197 / 856

Step 4:
When dividing 5197 by 856, we get 6 with a remainder of 61.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 5136 from 5197, we get 61.
Include the next digit (9) from the dividend after 61, then repeat: 619 / 856

Advancing to step 5:
The number 856 fits into 619 0 times, leaving a remainder of 619.
The next digit of our result is 0. 
Result so far: 60.0
If we take 0 away from 619, we end up with 619.
Bring next digit (6) of the dividend behind the 619 and repeat the process: 6196 / 856

Let's proceed to step 6:
The number 856 fits into 6196 7 times, leaving a remainder of 204.
Put 7 as the next digit of the answer. 
Result so far: 607.0
The remainder is 204 after subtracting 5992 from 6196.
Append the next digit (7) from the dividend to 204 and continue with: 2047 / 856

Advancing to step 7:
If we divide 2047 by 856, we get 2 and a remainder of 335.
The next digit of our result is 2. 
Result so far: 6072.0
If we subtract 1712 from 2047, we get 335.
Bring next digit (0) of the dividend behind the 335 and repeat the process: 3350 / 856

Step 8:
The number 856 fits into 3350 3 times, leaving a remainder of 782.
The number 3 becomes the next digit in our result. 
Result so far: 60723.0
If we take 2568 away from 3350, we end up with 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Going ahead to step 9:
If we divide 7820 by 856, we get 9 and a remainder of 116.
Put 9 as the next digit of the answer. 
Result so far: 60723.9
Subtract 7704 from 7820 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 10:
If we divide 1160 by 856, we get 1 and a remainder of 304.
Use 1 as the next digit of our solution. 
Result so far: 60723.91
If we subtract 856 from 1160, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 11:
If we divide 3040 by 856, we get 3 and a remainder of 472.
The number 3 becomes the next digit in our result. 
Result so far: 60723.913
If we take 2568 away from 3040, we end up with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Moving on to step 12:
4720 divided by 856 is 5 with a remainder of 440.
Record the quotient 5 as the next digit in the result. 
Result so far: 60723.9135
The remainder is 440 after subtracting 4280 from 4720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 13:
856 goes into 4400 5 times with a remainder of 120.
The next digit of our result is 5. 
Result so far: 60723.91355
If we take 4280 away from 4400, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The quotient of the division is 60723.91355, and the remainder is 0.00012.
