Let's divide 73897982 by 856
The aim is to understand the frequency of 856 in 73897982.

Moving on to step 1:
856 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 856

Let's proceed to step 2:
If we divide 73 by 856, we get 0 and a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Bring next digit (8) of the dividend behind the 73 and repeat the process: 738 / 856

Step 3:
856 can be fit into 738 0 times, resulting in a remainder of 738.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 738 and we're left with 738.
Fetch the next digit (9) from the dividend, attach it to 738 and continue: 7389 / 856

Advancing to step 4:
856 goes into 7389 8 times with a remainder of 541.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 541 after subtracting 6848 from 7389.
Append the next digit (7) from the dividend to 541 and continue with: 5417 / 856

Let's proceed to step 5:
856 goes into 5417 6 times with a remainder of 281.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtract 5136 from 5417 to get 281.
Append the next digit (9) from the dividend to 281 and continue with: 2819 / 856

Step 6:
856 goes into 2819 3 times with a remainder of 251.
Record the quotient 3 as the next digit in the result. 
Result so far: 863.0
Deduct 2568 from 2819 and we're left with 251.
Append the next digit (8) from the dividend to 251 and continue with: 2518 / 856

Let's proceed to step 7:
The number 856 fits into 2518 2 times, leaving a remainder of 806.
Write down 2 as next digit of the result. 
Result so far: 8632.0
Subtracting 1712 from 2518 leaves us with 806.
Append the next digit (2) from the dividend to 806 and continue with: 8062 / 856

Step 8:
When dividing 8062 by 856, we get 9 with a remainder of 358.
The number 9 becomes the next digit in our result. 
Result so far: 86329.0
Subtracting 7704 from 8062 leaves us with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 9:
If we divide 3580 by 856, we get 4 and a remainder of 156.
Record the quotient 4 as the next digit in the result. 
Result so far: 86329.4
Subtracting 3424 from 3580 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 10:
The number 856 fits into 1560 1 times, leaving a remainder of 704.
Write down 1 as next digit of the result. 
Result so far: 86329.41
If we take 856 away from 1560, we end up with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Going ahead to step 11:
7040 divided by 856 is 8 with a remainder of 192.
Write down 8 as next digit of the result. 
Result so far: 86329.418
If we subtract 6848 from 7040, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 12:
1920 divided by 856 is 2 with a remainder of 208.
Write down 2 as next digit of the result. 
Result so far: 86329.4182
Subtract 1712 from 1920 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 13:
If we divide 2080 by 856, we get 2 and a remainder of 368.
The number 2 becomes the next digit in our result. 
Result so far: 86329.41822
The remainder is 368 after subtracting 1712 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The final outcome is 86329.41822, with a leftover of 0.000368.
