Let's divide 853058 by 20
The aim is to understand the frequency of 20 in 853058.

Advancing to step 1:
The number 20 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 20

Step 2:
The number 20 fits into 85 4 times, leaving a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 5 after subtracting 80 from 85.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 20

Going ahead to step 3:
When dividing 53 by 20, we get 2 with a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Deduct 40 from 53 and we're left with 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 20

Let's proceed to step 4:
The number 20 fits into 130 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 426.0
Deduct 120 from 130 and we're left with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 20

Step 5:
When dividing 105 by 20, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 4265.0
Subtract 100 from 105 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 20

Advancing to step 6:
58 divided by 20 is 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 42652.0
The remainder is 18 after subtracting 40 from 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
20 goes into 180 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 42652.9
The remainder is 0 after subtracting 180 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 42652.9
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 42652.9
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 42652.9, with a leftover of 0.0.
