Let's divide 90336501 by 586
The aim is to understand the frequency of 586 in 90336501.

Going ahead to step 1:
The number 586 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 586

Step 2:
The number 586 fits into 90 0 times, leaving a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Grab the next digit (3) from the dividend, add it to 90, then carry on: 903 / 586

On to step 3:
The number 586 fits into 903 1 times, leaving a remainder of 317.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 586 from 903 and we're left with 317.
Bring next digit (3) of the dividend behind the 317 and repeat the process: 3173 / 586

Let's proceed to step 4:
586 goes into 3173 5 times with a remainder of 243.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 2930 from 3173 and we're left with 243.
Bring next digit (6) of the dividend behind the 243 and repeat the process: 2436 / 586

On to step 5:
586 goes into 2436 4 times with a remainder of 92.
Use 4 as the next digit of our solution. 
Result so far: 154.0
Subtracting 2344 from 2436 leaves us with 92.
Fetch the next digit (5) from the dividend, attach it to 92 and continue: 925 / 586

Moving on to step 6:
The number 586 fits into 925 1 times, leaving a remainder of 339.
Write down 1 as next digit of the result. 
Result so far: 1541.0
Deduct 586 from 925 and we're left with 339.
Fetch the next digit (0) from the dividend, attach it to 339 and continue: 3390 / 586

Moving on to step 7:
When dividing 3390 by 586, we get 5 with a remainder of 460.
Write down 5 as next digit of the result. 
Result so far: 15415.0
If we subtract 2930 from 3390, we get 460.
Append the next digit (1) from the dividend to 460 and continue with: 4601 / 586

Step 8:
If we divide 4601 by 586, we get 7 and a remainder of 499.
The next digit of our result is 7. 
Result so far: 154157.0
Subtract 4102 from 4601 to get 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

On to step 9:
When dividing 4990 by 586, we get 8 with a remainder of 302.
Use 8 as the next digit of our solution. 
Result so far: 154157.8
The remainder is 302 after subtracting 4688 from 4990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Step 10:
586 can be fit into 3020 5 times, resulting in a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 154157.85
Subtract 2930 from 3020 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 11:
When dividing 900 by 586, we get 1 with a remainder of 314.
Write down 1 as next digit of the result. 
Result so far: 154157.851
Subtract 586 from 900 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Let's proceed to step 12:
The number 586 fits into 3140 5 times, leaving a remainder of 210.
The next digit of our result is 5. 
Result so far: 154157.8515
The remainder is 210 after subtracting 2930 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 13:
586 can be fit into 2100 3 times, resulting in a remainder of 342.
The number 3 becomes the next digit in our result. 
Result so far: 154157.85153
Subtract 1758 from 2100 to get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Going ahead to step 14:
The number 586 fits into 3420 5 times, leaving a remainder of 490.
Use 5 as the next digit of our solution. 
Result so far: 154157.851535
Subtract 2930 from 3420 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Going ahead to step 15:
586 goes into 4900 8 times with a remainder of 212.
Record the quotient 8 as the next digit in the result. 
Result so far: 154157.8515358
The remainder is 212 after subtracting 4688 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 16:
586 can be fit into 2120 3 times, resulting in a remainder of 362.
Use 3 as the next digit of our solution. 
Result so far: 154157.85153583
The remainder is 362 after subtracting 1758 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

The final outcome is 154157.85153583, with a leftover of 3.62e-07.
