25451366 ÷ 394 
We want to figure out the number of times 25451366 can be divided by 394.

Going ahead to step 1:
The number 394 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 394

Step 2:
394 goes into 25 0 times with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 394

Step 3:
254 divided by 394 is 0 with a remainder of 254.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 254, we get 254.
Grab the next digit (5) from the dividend, add it to 254, then carry on: 2545 / 394

On to step 4:
394 can be fit into 2545 6 times, resulting in a remainder of 181.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 2364 away from 2545, we end up with 181.
Take the next digit (1) from the dividend and append it to 181, then repeat: 1811 / 394

Step 5:
The number 394 fits into 1811 4 times, leaving a remainder of 235.
Write down 4 as next digit of the result. 
Result so far: 64.0
The remainder is 235 after subtracting 1576 from 1811.
Include the next digit (3) from the dividend after 235, then repeat: 2353 / 394

Moving on to step 6:
If we divide 2353 by 394, we get 5 and a remainder of 383.
Write down 5 as next digit of the result. 
Result so far: 645.0
If we subtract 1970 from 2353, we get 383.
Take the next digit (6) from the dividend and append it to 383, then repeat: 3836 / 394

Going ahead to step 7:
394 can be fit into 3836 9 times, resulting in a remainder of 290.
Write down 9 as next digit of the result. 
Result so far: 6459.0
If we take 3546 away from 3836, we end up with 290.
Include the next digit (6) from the dividend after 290, then repeat: 2906 / 394

On to step 8:
394 goes into 2906 7 times with a remainder of 148.
The next digit of our result is 7. 
Result so far: 64597.0
If we subtract 2758 from 2906, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 9:
The number 394 fits into 1480 3 times, leaving a remainder of 298.
Use 3 as the next digit of our solution. 
Result so far: 64597.3
If we subtract 1182 from 1480, we get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Moving on to step 10:
The number 394 fits into 2980 7 times, leaving a remainder of 222.
The number 7 becomes the next digit in our result. 
Result so far: 64597.37
Subtract 2758 from 2980 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 11:
2220 divided by 394 is 5 with a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 64597.375
Deduct 1970 from 2220 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 12:
If we divide 2500 by 394, we get 6 and a remainder of 136.
Write down 6 as next digit of the result. 
Result so far: 64597.3756
If we take 2364 away from 2500, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 13:
When dividing 1360 by 394, we get 3 with a remainder of 178.
Use 3 as the next digit of our solution. 
Result so far: 64597.37563
If we subtract 1182 from 1360, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Let's proceed to step 14:
If we divide 1780 by 394, we get 4 and a remainder of 204.
Use 4 as the next digit of our solution. 
Result so far: 64597.375634
If we take 1576 away from 1780, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 15:
394 can be fit into 2040 5 times, resulting in a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 64597.3756345
If we subtract 1970 from 2040, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 16:
394 can be fit into 700 1 times, resulting in a remainder of 306.
Write down 1 as next digit of the result. 
Result so far: 64597.37563451
If we subtract 394 from 700, we get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

The final result is 64597.37563451 with a remainder of 3.06e-07.
