591991 divided by 36 
The aim is to understand the frequency of 36 in 591991.

Going ahead to step 1:
If we divide 5 by 36, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 36

Going ahead to step 2:
When dividing 59 by 36, we get 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 23 after subtracting 36 from 59.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 36

Advancing to step 3:
231 divided by 36 is 6 with a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 16.0
The remainder is 15 after subtracting 216 from 231.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 36

On to step 4:
The number 36 fits into 159 4 times, leaving a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 164.0
The remainder is 15 after subtracting 144 from 159.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 36

Let's proceed to step 5:
36 goes into 159 4 times with a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 1644.0
If we subtract 144 from 159, we get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 36

Going ahead to step 6:
If we divide 151 by 36, we get 4 and a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 16444.0
If we subtract 144 from 151, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
The number 36 fits into 70 1 times, leaving a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 16444.1
The remainder is 34 after subtracting 36 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
36 goes into 340 9 times with a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 16444.19
The remainder is 16 after subtracting 324 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
36 goes into 160 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 16444.194
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
If we divide 160 by 36, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 16444.1944
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 16444.1944, and the remainder is 0.00016.
