We look at the division of 4025630 by 251 
Let's see how many times 251 fits into 4025630.

Moving on to step 1:
The number 251 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 251

Step 2:
If we divide 40 by 251, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Bring next digit (2) of the dividend behind the 40 and repeat the process: 402 / 251

Going ahead to step 3:
251 can be fit into 402 1 times, resulting in a remainder of 151.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 251 from 402 leaves us with 151.
Include the next digit (5) from the dividend after 151, then repeat: 1515 / 251

Going ahead to step 4:
If we divide 1515 by 251, we get 6 and a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 1506 from 1515 to get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 251

Advancing to step 5:
When dividing 96 by 251, we get 0 with a remainder of 96.
Use 0 as the next digit of our solution. 
Result so far: 160.0
Subtracting 0 from 96 leaves us with 96.
Grab the next digit (3) from the dividend, add it to 96, then carry on: 963 / 251

Let's proceed to step 6:
251 goes into 963 3 times with a remainder of 210.
Write down 3 as next digit of the result. 
Result so far: 1603.0
If we take 753 away from 963, we end up with 210.
Include the next digit (0) from the dividend after 210, then repeat: 2100 / 251

Going ahead to step 7:
2100 divided by 251 is 8 with a remainder of 92.
Put 8 as the next digit of the answer. 
Result so far: 16038.0
Subtract 2008 from 2100 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 8:
251 goes into 920 3 times with a remainder of 167.
Use 3 as the next digit of our solution. 
Result so far: 16038.3
Subtract 753 from 920 to get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Step 9:
The number 251 fits into 1670 6 times, leaving a remainder of 164.
Use 6 as the next digit of our solution. 
Result so far: 16038.36
If we subtract 1506 from 1670, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 10:
1640 divided by 251 is 6 with a remainder of 134.
The next digit of our result is 6. 
Result so far: 16038.366
Deduct 1506 from 1640 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

The quotient of the division is 16038.366, and the remainder is 0.0134.
