Let's divide 25283921 by 678
Let's see how many times 678 fits into 25283921.

Going ahead to step 1:
If we divide 2 by 678, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 678

Moving on to step 2:
The number 678 fits into 25 0 times, leaving a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Append the next digit (2) from the dividend to 25 and continue with: 252 / 678

Let's proceed to step 3:
When dividing 252 by 678, we get 0 with a remainder of 252.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 252 leaves us with 252.
Include the next digit (8) from the dividend after 252, then repeat: 2528 / 678

Going ahead to step 4:
2528 divided by 678 is 3 with a remainder of 494.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 2034 from 2528 leaves us with 494.
Fetch the next digit (3) from the dividend, attach it to 494 and continue: 4943 / 678

Step 5:
4943 divided by 678 is 7 with a remainder of 197.
Write down 7 as next digit of the result. 
Result so far: 37.0
Deduct 4746 from 4943 and we're left with 197.
Bring next digit (9) of the dividend behind the 197 and repeat the process: 1979 / 678

Going ahead to step 6:
The number 678 fits into 1979 2 times, leaving a remainder of 623.
Use 2 as the next digit of our solution. 
Result so far: 372.0
If we subtract 1356 from 1979, we get 623.
Take the next digit (2) from the dividend and append it to 623, then repeat: 6232 / 678

Going ahead to step 7:
678 can be fit into 6232 9 times, resulting in a remainder of 130.
Use 9 as the next digit of our solution. 
Result so far: 3729.0
Subtract 6102 from 6232 to get 130.
Fetch the next digit (1) from the dividend, attach it to 130 and continue: 1301 / 678

Advancing to step 8:
If we divide 1301 by 678, we get 1 and a remainder of 623.
The number 1 becomes the next digit in our result. 
Result so far: 37291.0
Deduct 678 from 1301 and we're left with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Step 9:
678 goes into 6230 9 times with a remainder of 128.
Record the quotient 9 as the next digit in the result. 
Result so far: 37291.9
The remainder is 128 after subtracting 6102 from 6230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 10:
If we divide 1280 by 678, we get 1 and a remainder of 602.
Use 1 as the next digit of our solution. 
Result so far: 37291.91
Subtract 678 from 1280 to get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Advancing to step 11:
The number 678 fits into 6020 8 times, leaving a remainder of 596.
Record the quotient 8 as the next digit in the result. 
Result so far: 37291.918
If we subtract 5424 from 6020, we get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

On to step 12:
5960 divided by 678 is 8 with a remainder of 536.
The number 8 becomes the next digit in our result. 
Result so far: 37291.9188
If we take 5424 away from 5960, we end up with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

The final outcome is 37291.9188, with a leftover of 0.00536.
