25974025 ÷ 389 
Our goal is to divide 25974025 by 389.

On to step 1:
389 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 389

Step 2:
25 divided by 389 is 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 389

Step 3:
389 goes into 259 0 times with a remainder of 259.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 259, we end up with 259.
Fetch the next digit (7) from the dividend, attach it to 259 and continue: 2597 / 389

Let's proceed to step 4:
2597 divided by 389 is 6 with a remainder of 263.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 2334 from 2597 leaves us with 263.
Bring next digit (4) of the dividend behind the 263 and repeat the process: 2634 / 389

On to step 5:
If we divide 2634 by 389, we get 6 and a remainder of 300.
Write down 6 as next digit of the result. 
Result so far: 66.0
If we subtract 2334 from 2634, we get 300.
Take the next digit (0) from the dividend and append it to 300, then repeat: 3000 / 389

Step 6:
389 goes into 3000 7 times with a remainder of 277.
The number 7 becomes the next digit in our result. 
Result so far: 667.0
Subtracting 2723 from 3000 leaves us with 277.
Append the next digit (2) from the dividend to 277 and continue with: 2772 / 389

Moving on to step 7:
The number 389 fits into 2772 7 times, leaving a remainder of 49.
The next digit of our result is 7. 
Result so far: 6677.0
Deduct 2723 from 2772 and we're left with 49.
Grab the next digit (5) from the dividend, add it to 49, then carry on: 495 / 389

Step 8:
If we divide 495 by 389, we get 1 and a remainder of 106.
The next digit of our result is 1. 
Result so far: 66771.0
Deduct 389 from 495 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 9:
The number 389 fits into 1060 2 times, leaving a remainder of 282.
The next digit of our result is 2. 
Result so far: 66771.2
The remainder is 282 after subtracting 778 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 10:
389 can be fit into 2820 7 times, resulting in a remainder of 97.
Record the quotient 7 as the next digit in the result. 
Result so far: 66771.27
If we subtract 2723 from 2820, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 11:
970 divided by 389 is 2 with a remainder of 192.
The number 2 becomes the next digit in our result. 
Result so far: 66771.272
Deduct 778 from 970 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 12:
If we divide 1920 by 389, we get 4 and a remainder of 364.
Record the quotient 4 as the next digit in the result. 
Result so far: 66771.2724
If we take 1556 away from 1920, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 13:
The number 389 fits into 3640 9 times, leaving a remainder of 139.
Write down 9 as next digit of the result. 
Result so far: 66771.27249
If we take 3501 away from 3640, we end up with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Moving on to step 14:
The number 389 fits into 1390 3 times, leaving a remainder of 223.
The number 3 becomes the next digit in our result. 
Result so far: 66771.272493
Subtracting 1167 from 1390 leaves us with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Step 15:
The number 389 fits into 2230 5 times, leaving a remainder of 285.
Record the quotient 5 as the next digit in the result. 
Result so far: 66771.2724935
If we subtract 1945 from 2230, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 16:
389 can be fit into 2850 7 times, resulting in a remainder of 127.
Write down 7 as next digit of the result. 
Result so far: 66771.27249357
If we subtract 2723 from 2850, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

The final outcome is 66771.27249357, with a leftover of 1.27e-07.
