853064 divided by 20 
Our goal is to divide 853064 by 20.

Advancing to step 1:
20 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 20

Advancing to step 2:
20 goes into 85 4 times with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 80 from 85 to get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 20

Moving on to step 3:
20 can be fit into 53 2 times, resulting in a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtracting 40 from 53 leaves us with 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 20

Step 4:
The number 20 fits into 130 6 times, leaving a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 426.0
Deduct 120 from 130 and we're left with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 20

Step 5:
20 can be fit into 106 5 times, resulting in a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 4265.0
If we take 100 away from 106, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 20

Advancing to step 6:
When dividing 64 by 20, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 42653.0
The remainder is 4 after subtracting 60 from 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
20 goes into 40 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 42653.2
If we take 40 away from 40, 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.

On to step 8:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 42653.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 42653.2
If we subtract 0 from 0, we get 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 result is 42653.2 with a remainder of 0.0.
