25983489 ÷ 378 
Our goal is to divide 25983489 by 378.

Going ahead to step 1:
378 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 378

Moving on to step 2:
The number 378 fits into 25 0 times, leaving a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 378

Advancing to step 3:
When dividing 259 by 378, we get 0 with a remainder of 259.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 259 and we're left with 259.
Append the next digit (8) from the dividend to 259 and continue with: 2598 / 378

Going ahead to step 4:
378 can be fit into 2598 6 times, resulting in a remainder of 330.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 2268 from 2598, we get 330.
Append the next digit (3) from the dividend to 330 and continue with: 3303 / 378

On to step 5:
When dividing 3303 by 378, we get 8 with a remainder of 279.
The next digit of our result is 8. 
Result so far: 68.0
Deduct 3024 from 3303 and we're left with 279.
Take the next digit (4) from the dividend and append it to 279, then repeat: 2794 / 378

On to step 6:
If we divide 2794 by 378, we get 7 and a remainder of 148.
Put 7 as the next digit of the answer. 
Result so far: 687.0
The remainder is 148 after subtracting 2646 from 2794.
Grab the next digit (8) from the dividend, add it to 148, then carry on: 1488 / 378

On to step 7:
1488 divided by 378 is 3 with a remainder of 354.
Write down 3 as next digit of the result. 
Result so far: 6873.0
The remainder is 354 after subtracting 1134 from 1488.
Grab the next digit (9) from the dividend, add it to 354, then carry on: 3549 / 378

Advancing to step 8:
378 goes into 3549 9 times with a remainder of 147.
Put 9 as the next digit of the answer. 
Result so far: 68739.0
If we take 3402 away from 3549, we end up with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Step 9:
If we divide 1470 by 378, we get 3 and a remainder of 336.
Put 3 as the next digit of the answer. 
Result so far: 68739.3
The remainder is 336 after subtracting 1134 from 1470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 10:
The number 378 fits into 3360 8 times, leaving a remainder of 336.
Use 8 as the next digit of our solution. 
Result so far: 68739.38
If we subtract 3024 from 3360, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 11:
When dividing 3360 by 378, we get 8 with a remainder of 336.
Use 8 as the next digit of our solution. 
Result so far: 68739.388
If we subtract 3024 from 3360, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

After the division, we end up with 68739.388 and a remainder of 0.0336.
