878690 ÷ 49 
Our goal is to divide 878690 by 49.

Step 1:
The number 49 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 49

Let's proceed to step 2:
The number 49 fits into 87 1 times, leaving a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 49 away from 87, we end up with 38.
Take the next digit (8) from the dividend and append it to 38, then repeat: 388 / 49

Going ahead to step 3:
If we divide 388 by 49, we get 7 and a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 343 from 388 and we're left with 45.
Fetch the next digit (6) from the dividend, attach it to 45 and continue: 456 / 49

Moving on to step 4:
The number 49 fits into 456 9 times, leaving a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 179.0
Subtracting 441 from 456 leaves us with 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 49

Step 5:
If we divide 159 by 49, we get 3 and a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 1793.0
Subtracting 147 from 159 leaves us with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 49

On to step 6:
120 divided by 49 is 2 with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 17932.0
Subtracting 98 from 120 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
49 can be fit into 220 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 17932.4
Deduct 196 from 220 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
49 goes into 240 4 times with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 17932.44
Deduct 196 from 240 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 17932.44, with a leftover of 0.044.
