We look at the division of 25217 by 40 
Our goal is to divide 25217 by 40.

Moving on to step 1:
If we divide 2 by 40, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 40

Let's proceed to step 2:
40 goes into 25 0 times with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 40

Moving on to step 3:
The number 40 fits into 252 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 12 after subtracting 240 from 252.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 40

Going ahead to step 4:
40 goes into 121 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Deduct 120 from 121 and we're left with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 40

Step 5:
40 goes into 17 0 times with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 630.0
Deduct 0 from 17 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 6:
170 divided by 40 is 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 630.4
Subtract 160 from 170 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
40 can be fit into 100 2 times, resulting in a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 630.42
Deduct 80 from 100 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
200 divided by 40 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 630.425
If we subtract 200 from 200, 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:
When dividing 0 by 40, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 630.425
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.

Step 10:
If we divide 0 by 40, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 630.425
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 630.425, with a leftover of 0.0.
