We look at the division of 625851 by 20 
Our goal is to divide 625851 by 20.

Let's proceed to step 1:
When dividing 6 by 20, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 20

On to step 2:
20 can be fit into 62 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 60 from 62, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 20

Let's proceed to step 3:
25 divided by 20 is 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 31.0
If we take 20 away from 25, we end up with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 20

Step 4:
If we divide 58 by 20, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 312.0
Subtract 40 from 58 to get 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 20

Step 5:
When dividing 185 by 20, we get 9 with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 3129.0
Subtract 180 from 185 to get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 20

On to step 6:
20 goes into 51 2 times with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 31292.0
If we subtract 40 from 51, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
The number 20 fits into 110 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 31292.5
If we take 100 away from 110, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 31292.55
Subtracting 100 from 100 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 quotient of the division is 31292.55, and the remainder is 0.0.
