We divide 85982837 by 646
The aim is to understand the frequency of 646 in 85982837.

Moving on to step 1:
646 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 646

Moving on to step 2:
When dividing 85 by 646, we get 0 with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Fetch the next digit (9) from the dividend, attach it to 85 and continue: 859 / 646

Let's proceed to step 3:
859 divided by 646 is 1 with a remainder of 213.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 646 from 859, we get 213.
Append the next digit (8) from the dividend to 213 and continue with: 2138 / 646

Moving on to step 4:
646 can be fit into 2138 3 times, resulting in a remainder of 200.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 1938 from 2138 leaves us with 200.
Include the next digit (2) from the dividend after 200, then repeat: 2002 / 646

Advancing to step 5:
646 goes into 2002 3 times with a remainder of 64.
Write down 3 as next digit of the result. 
Result so far: 133.0
Subtract 1938 from 2002 to get 64.
Fetch the next digit (8) from the dividend, attach it to 64 and continue: 648 / 646

Step 6:
When dividing 648 by 646, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1331.0
The remainder is 2 after subtracting 646 from 648.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 646

Let's proceed to step 7:
646 can be fit into 23 0 times, resulting in a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 13310.0
Subtracting 0 from 23 leaves us with 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 646

Moving on to step 8:
If we divide 237 by 646, we get 0 and a remainder of 237.
Write down 0 as next digit of the result. 
Result so far: 133100.0
If we take 0 away from 237, we end up with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Going ahead to step 9:
When dividing 2370 by 646, we get 3 with a remainder of 432.
The next digit of our result is 3. 
Result so far: 133100.3
If we take 1938 away from 2370, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Advancing to step 10:
When dividing 4320 by 646, we get 6 with a remainder of 444.
Use 6 as the next digit of our solution. 
Result so far: 133100.36
If we take 3876 away from 4320, we end up with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

On to step 11:
The number 646 fits into 4440 6 times, leaving a remainder of 564.
The number 6 becomes the next digit in our result. 
Result so far: 133100.366
The remainder is 564 after subtracting 3876 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

In conclusion, the division gives 133100.366 with a balance of 0.0564.
