871573 ÷ 49 
Let's see how many times 49 fits into 871573.

Going ahead to step 1:
49 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 49

Going ahead to step 2:
When dividing 87 by 49, we get 1 with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 49 from 87, we get 38.
Append the next digit (1) from the dividend to 38 and continue with: 381 / 49

Step 3:
If we divide 381 by 49, we get 7 and a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 38 after subtracting 343 from 381.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 49

Step 4:
385 divided by 49 is 7 with a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 177.0
If we subtract 343 from 385, we get 42.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 49

Going ahead to step 5:
427 divided by 49 is 8 with a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 1778.0
If we subtract 392 from 427, we get 35.
Fetch the next digit (3) from the dividend, attach it to 35 and continue: 353 / 49

Advancing to step 6:
353 divided by 49 is 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 17787.0
If we subtract 343 from 353, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
When dividing 100 by 49, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 17787.2
If we take 98 away from 100, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
The number 49 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 17787.2
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
If we divide 200 by 49, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 17787.204
Deduct 196 from 200 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
49 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 17787.204
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
49 goes into 400 8 times with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 17787.20408
Deduct 392 from 400 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
49 goes into 80 1 times with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 17787.204081
If we take 49 away from 80, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 13:
The number 49 fits into 310 6 times, leaving a remainder of 16.
The next digit of our result is 6. 
Result so far: 17787.2040816
If we take 294 away from 310, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
49 goes into 160 3 times with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 17787.20408163
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 17787.20408163, with a leftover of 1.3e-08.
