878890 ÷ 49 
We want to figure out the number of times 878890 can be divided by 49.

Step 1:
8 divided by 49 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 49

Moving on to step 2:
49 goes into 87 1 times with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 49 from 87 to get 38.
Append the next digit (8) from the dividend to 38 and continue with: 388 / 49

Going ahead to step 3:
The number 49 fits into 388 7 times, leaving a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 343 from 388 to get 45.
Include the next digit (8) from the dividend after 45, then repeat: 458 / 49

Going ahead to step 4:
458 divided by 49 is 9 with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 179.0
Subtract 441 from 458 to get 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 49

On to step 5:
49 goes into 179 3 times with a remainder of 32.
Record the quotient 3 as the next digit in the result. 
Result so far: 1793.0
Subtracting 147 from 179 leaves us with 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 49

Let's proceed to step 6:
If we divide 320 by 49, we get 6 and a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 17936.0
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
When dividing 260 by 49, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 17936.5
Deduct 245 from 260 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
49 can be fit into 150 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 17936.53
If we take 147 away from 150, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
When dividing 30 by 49, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 17936.53
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
300 divided by 49 is 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 17936.5306
Subtracting 294 from 300 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
If we divide 60 by 49, we get 1 and a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 17936.53061
Subtracting 49 from 60 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 12:
If we divide 110 by 49, we get 2 and a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 17936.530612
Subtract 98 from 110 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 13:
49 goes into 120 2 times with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 17936.5306122
Subtract 98 from 120 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 17936.5306122 with a remainder of 2.2e-07.
