We look at the division of 85970983 by 584 
The aim is to understand the frequency of 584 in 85970983.

Going ahead to step 1:
The number 584 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 584

Going ahead to step 2:
The number 584 fits into 85 0 times, leaving a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Include the next digit (9) from the dividend after 85, then repeat: 859 / 584

On to step 3:
When dividing 859 by 584, we get 1 with a remainder of 275.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 584 from 859 leaves us with 275.
Grab the next digit (7) from the dividend, add it to 275, then carry on: 2757 / 584

Let's proceed to step 4:
584 goes into 2757 4 times with a remainder of 421.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 421 after subtracting 2336 from 2757.
Include the next digit (0) from the dividend after 421, then repeat: 4210 / 584

Advancing to step 5:
The number 584 fits into 4210 7 times, leaving a remainder of 122.
The number 7 becomes the next digit in our result. 
Result so far: 147.0
If we subtract 4088 from 4210, we get 122.
Take the next digit (9) from the dividend and append it to 122, then repeat: 1229 / 584

On to step 6:
584 goes into 1229 2 times with a remainder of 61.
The number 2 becomes the next digit in our result. 
Result so far: 1472.0
Deduct 1168 from 1229 and we're left with 61.
Include the next digit (8) from the dividend after 61, then repeat: 618 / 584

Moving on to step 7:
If we divide 618 by 584, we get 1 and a remainder of 34.
The next digit of our result is 1. 
Result so far: 14721.0
If we subtract 584 from 618, we get 34.
Append the next digit (3) from the dividend to 34 and continue with: 343 / 584

Moving on to step 8:
584 can be fit into 343 0 times, resulting in a remainder of 343.
Put 0 as the next digit of the answer. 
Result so far: 147210.0
If we subtract 0 from 343, we get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Let's proceed to step 9:
The number 584 fits into 3430 5 times, leaving a remainder of 510.
Put 5 as the next digit of the answer. 
Result so far: 147210.5
Subtract 2920 from 3430 to get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Moving on to step 10:
5100 divided by 584 is 8 with a remainder of 428.
The number 8 becomes the next digit in our result. 
Result so far: 147210.58
Deduct 4672 from 5100 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

On to step 11:
When dividing 4280 by 584, we get 7 with a remainder of 192.
The number 7 becomes the next digit in our result. 
Result so far: 147210.587
Subtract 4088 from 4280 to 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.

Advancing to step 12:
The number 584 fits into 1920 3 times, leaving a remainder of 168.
Put 3 as the next digit of the answer. 
Result so far: 147210.5873
The remainder is 168 after subtracting 1752 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 13:
If we divide 1680 by 584, we get 2 and a remainder of 512.
The number 2 becomes the next digit in our result. 
Result so far: 147210.58732
The remainder is 512 after subtracting 1168 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Step 14:
The number 584 fits into 5120 8 times, leaving a remainder of 448.
The next digit of our result is 8. 
Result so far: 147210.587328
Subtracting 4672 from 5120 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 15:
584 goes into 4480 7 times with a remainder of 392.
Put 7 as the next digit of the answer. 
Result so far: 147210.5873287
Deduct 4088 from 4480 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 16:
The number 584 fits into 3920 6 times, leaving a remainder of 416.
Put 6 as the next digit of the answer. 
Result so far: 147210.58732876
Subtracting 3504 from 3920 leaves us 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.

In conclusion, the division gives 147210.58732876 with a balance of 4.16e-07.
