We're dividing 837756 by 20 
The aim is to understand the frequency of 20 in 837756.

On to step 1:
8 divided by 20 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 20

On to step 2:
When dividing 83 by 20, we get 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 80 from 83 leaves us with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 20

On to step 3:
When dividing 37 by 20, we get 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Deduct 20 from 37 and we're left with 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 20

On to step 4:
177 divided by 20 is 8 with a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 418.0
If we subtract 160 from 177, we get 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 20

Moving on to step 5:
When dividing 175 by 20, we get 8 with a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 4188.0
If we subtract 160 from 175, we get 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 20

Moving on to step 6:
When dividing 156 by 20, we get 7 with a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 41887.0
Subtract 140 from 156 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.

Let's proceed to step 7:
When dividing 160 by 20, we get 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 41887.8
Subtracting 160 from 160 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.

Moving on to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 41887.8
If we take 0 away from 0, we end up 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.

Let's proceed to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 41887.8
Deduct 0 from 0 and we're left 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 quotient of the division is 41887.8, and the remainder is 0.0.
