419890 ÷ 36 
The aim is to understand the frequency of 36 in 419890.

Step 1:
36 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 36

Going ahead to step 2:
36 can be fit into 41 1 times, resulting in a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 36 from 41 and we're left with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 36

Going ahead to step 3:
When dividing 59 by 36, we get 1 with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 23 after subtracting 36 from 59.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 36

Going ahead to step 4:
36 goes into 238 6 times with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
If we subtract 216 from 238, we get 22.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 36

Going ahead to step 5:
36 can be fit into 229 6 times, resulting in a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 1166.0
Subtracting 216 from 229 leaves us with 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 36

Advancing to step 6:
The number 36 fits into 130 3 times, leaving a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 11663.0
If we subtract 108 from 130, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
36 can be fit into 220 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 11663.6
The remainder is 4 after subtracting 216 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
The number 36 fits into 40 1 times, leaving a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 11663.61
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
When dividing 40 by 36, we get 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 11663.611
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 11663.611, with a leftover of 0.0004.
