Let's divide 15405769 by 278
We're looking to find how many times 278 goes into 15405769.

Moving on to step 1:
If we divide 1 by 278, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 278

Moving on to step 2:
The number 278 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 278

Let's proceed to step 3:
154 divided by 278 is 0 with a remainder of 154.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 154, we end up with 154.
Append the next digit (0) from the dividend to 154 and continue with: 1540 / 278

Advancing to step 4:
The number 278 fits into 1540 5 times, leaving a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 150 after subtracting 1390 from 1540.
Bring next digit (5) of the dividend behind the 150 and repeat the process: 1505 / 278

Going ahead to step 5:
278 goes into 1505 5 times with a remainder of 115.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
If we subtract 1390 from 1505, we get 115.
Append the next digit (7) from the dividend to 115 and continue with: 1157 / 278

Moving on to step 6:
1157 divided by 278 is 4 with a remainder of 45.
The next digit of our result is 4. 
Result so far: 554.0
If we take 1112 away from 1157, we end up with 45.
Include the next digit (6) from the dividend after 45, then repeat: 456 / 278

Going ahead to step 7:
If we divide 456 by 278, we get 1 and a remainder of 178.
Record the quotient 1 as the next digit in the result. 
Result so far: 5541.0
The remainder is 178 after subtracting 278 from 456.
Append the next digit (9) from the dividend to 178 and continue with: 1789 / 278

Step 8:
1789 divided by 278 is 6 with a remainder of 121.
Write down 6 as next digit of the result. 
Result so far: 55416.0
If we subtract 1668 from 1789, we get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 9:
278 goes into 1210 4 times with a remainder of 98.
The next digit of our result is 4. 
Result so far: 55416.4
Deduct 1112 from 1210 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 10:
If we divide 980 by 278, we get 3 and a remainder of 146.
The next digit of our result is 3. 
Result so far: 55416.43
Subtract 834 from 980 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 11:
278 goes into 1460 5 times with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 55416.435
Deduct 1390 from 1460 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 12:
278 can be fit into 700 2 times, resulting in a remainder of 144.
Record the quotient 2 as the next digit in the result. 
Result so far: 55416.4352
If we take 556 away from 700, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 13:
If we divide 1440 by 278, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 55416.43525
If we subtract 1390 from 1440, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 14:
When dividing 500 by 278, we get 1 with a remainder of 222.
Write down 1 as next digit of the result. 
Result so far: 55416.435251
Subtracting 278 from 500 leaves us with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Moving on to step 15:
278 can be fit into 2220 7 times, resulting in a remainder of 274.
The next digit of our result is 7. 
Result so far: 55416.4352517
Subtracting 1946 from 2220 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 16:
If we divide 2740 by 278, we get 9 and a remainder of 238.
Write down 9 as next digit of the result. 
Result so far: 55416.43525179
If we take 2502 away from 2740, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

After the division, we end up with 55416.43525179 and a remainder of 2.38e-07.
