We divide 25835245 by 421
We want to figure out the number of times 25835245 can be divided by 421.

Advancing to step 1:
421 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 421

On to step 2:
The number 421 fits into 25 0 times, leaving a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 421

Let's proceed to step 3:
421 goes into 258 0 times with a remainder of 258.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 258 and we're left with 258.
Fetch the next digit (3) from the dividend, attach it to 258 and continue: 2583 / 421

Going ahead to step 4:
The number 421 fits into 2583 6 times, leaving a remainder of 57.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 2526 from 2583, we get 57.
Include the next digit (5) from the dividend after 57, then repeat: 575 / 421

Step 5:
When dividing 575 by 421, we get 1 with a remainder of 154.
Write down 1 as next digit of the result. 
Result so far: 61.0
If we take 421 away from 575, we end up with 154.
Fetch the next digit (2) from the dividend, attach it to 154 and continue: 1542 / 421

Going ahead to step 6:
The number 421 fits into 1542 3 times, leaving a remainder of 279.
Put 3 as the next digit of the answer. 
Result so far: 613.0
If we take 1263 away from 1542, we end up with 279.
Fetch the next digit (4) from the dividend, attach it to 279 and continue: 2794 / 421

Let's proceed to step 7:
When dividing 2794 by 421, we get 6 with a remainder of 268.
Record the quotient 6 as the next digit in the result. 
Result so far: 6136.0
Subtract 2526 from 2794 to get 268.
Take the next digit (5) from the dividend and append it to 268, then repeat: 2685 / 421

Let's proceed to step 8:
When dividing 2685 by 421, we get 6 with a remainder of 159.
Write down 6 as next digit of the result. 
Result so far: 61366.0
Subtracting 2526 from 2685 leaves us with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 9:
1590 divided by 421 is 3 with a remainder of 327.
The number 3 becomes the next digit in our result. 
Result so far: 61366.3
If we subtract 1263 from 1590, we get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Step 10:
421 can be fit into 3270 7 times, resulting in a remainder of 323.
The next digit of our result is 7. 
Result so far: 61366.37
If we take 2947 away from 3270, we end up with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Advancing to step 11:
421 can be fit into 3230 7 times, resulting in a remainder of 283.
The number 7 becomes the next digit in our result. 
Result so far: 61366.377
If we take 2947 away from 3230, we end up with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

The final result is 61366.377 with a remainder of 0.0283.
