20449370 ÷ 278 
We're looking to find how many times 278 goes into 20449370.

Let's proceed to step 1:
278 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 278

Going ahead to step 2:
When dividing 20 by 278, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 278

Moving on to step 3:
The number 278 fits into 204 0 times, leaving a remainder of 204.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 204 after subtracting 0 from 204.
Grab the next digit (4) from the dividend, add it to 204, then carry on: 2044 / 278

Moving on to step 4:
When dividing 2044 by 278, we get 7 with a remainder of 98.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 1946 from 2044 and we're left with 98.
Fetch the next digit (9) from the dividend, attach it to 98 and continue: 989 / 278

Moving on to step 5:
278 can be fit into 989 3 times, resulting in a remainder of 155.
Use 3 as the next digit of our solution. 
Result so far: 73.0
Deduct 834 from 989 and we're left with 155.
Append the next digit (3) from the dividend to 155 and continue with: 1553 / 278

Advancing to step 6:
When dividing 1553 by 278, we get 5 with a remainder of 163.
The number 5 becomes the next digit in our result. 
Result so far: 735.0
If we take 1390 away from 1553, we end up with 163.
Take the next digit (7) from the dividend and append it to 163, then repeat: 1637 / 278

Going ahead to step 7:
The number 278 fits into 1637 5 times, leaving a remainder of 247.
The next digit of our result is 5. 
Result so far: 7355.0
Subtracting 1390 from 1637 leaves us with 247.
Include the next digit (0) from the dividend after 247, then repeat: 2470 / 278

Step 8:
When dividing 2470 by 278, we get 8 with a remainder of 246.
Record the quotient 8 as the next digit in the result. 
Result so far: 73558.0
If we take 2224 away from 2470, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 9:
If we divide 2460 by 278, we get 8 and a remainder of 236.
The next digit of our result is 8. 
Result so far: 73558.8
Subtracting 2224 from 2460 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 10:
2360 divided by 278 is 8 with a remainder of 136.
The number 8 becomes the next digit in our result. 
Result so far: 73558.88
The remainder is 136 after subtracting 2224 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The final outcome is 73558.88, with a leftover of 0.136.
