We look at the division of 85907620 by 586 
The aim is to understand the frequency of 586 in 85907620.

Moving on to step 1:
If we divide 8 by 586, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 586

Step 2:
586 can be fit into 85 0 times, resulting in a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Include the next digit (9) from the dividend after 85, then repeat: 859 / 586

Moving on to step 3:
586 can be fit into 859 1 times, resulting in a remainder of 273.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 273 after subtracting 586 from 859.
Grab the next digit (0) from the dividend, add it to 273, then carry on: 2730 / 586

On to step 4:
If we divide 2730 by 586, we get 4 and a remainder of 386.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 2344 from 2730 to get 386.
Append the next digit (7) from the dividend to 386 and continue with: 3867 / 586

Step 5:
The number 586 fits into 3867 6 times, leaving a remainder of 351.
Record the quotient 6 as the next digit in the result. 
Result so far: 146.0
If we subtract 3516 from 3867, we get 351.
Grab the next digit (6) from the dividend, add it to 351, then carry on: 3516 / 586

On to step 6:
If we divide 3516 by 586, we get 6 and a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 1466.0
If we subtract 3516 from 3516, we get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 586

Moving on to step 7:
If we divide 2 by 586, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 14660.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 586

Moving on to step 8:
586 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 146600.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
586 goes into 200 0 times with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 146600.0
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 10:
2000 divided by 586 is 3 with a remainder of 242.
The next digit of our result is 3. 
Result so far: 146600.03
Deduct 1758 from 2000 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Advancing to step 11:
When dividing 2420 by 586, we get 4 with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 146600.034
Deduct 2344 from 2420 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 12:
760 divided by 586 is 1 with a remainder of 174.
The next digit of our result is 1. 
Result so far: 146600.0341
If we subtract 586 from 760, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 13:
When dividing 1740 by 586, we get 2 with a remainder of 568.
The next digit of our result is 2. 
Result so far: 146600.03412
If we subtract 1172 from 1740, we get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

On to step 14:
If we divide 5680 by 586, we get 9 and a remainder of 406.
Write down 9 as next digit of the result. 
Result so far: 146600.034129
If we take 5274 away from 5680, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

On to step 15:
586 can be fit into 4060 6 times, resulting in a remainder of 544.
The next digit of our result is 6. 
Result so far: 146600.0341296
If we subtract 3516 from 4060, we get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Step 16:
5440 divided by 586 is 9 with a remainder of 166.
Record the quotient 9 as the next digit in the result. 
Result so far: 146600.03412969
If we take 5274 away from 5440, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

In conclusion, the division gives 146600.03412969 with a balance of 1.66e-07.
