We look at the division of 849871 by 49 
Our goal is to divide 849871 by 49.

Going ahead to step 1:
49 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 49

Moving on to step 2:
49 goes into 84 1 times with a remainder of 35.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 49 from 84 to get 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 49

Moving on to step 3:
359 divided by 49 is 7 with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 16 after subtracting 343 from 359.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 49

Let's proceed to step 4:
49 goes into 168 3 times with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 173.0
Subtracting 147 from 168 leaves us with 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 49

On to step 5:
49 can be fit into 217 4 times, resulting in a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 1734.0
The remainder is 21 after subtracting 196 from 217.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 49

Step 6:
211 divided by 49 is 4 with a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 17344.0
Subtracting 196 from 211 leaves us 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.

Let's proceed to step 7:
If we divide 150 by 49, we get 3 and a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 17344.3
Deduct 147 from 150 and we're left 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 8:
When dividing 30 by 49, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 17344.3
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
49 can be fit into 300 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 17344.306
If we subtract 294 from 300, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
49 goes into 60 1 times with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 17344.3061
Subtract 49 from 60 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
49 can be fit into 110 2 times, resulting in a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 17344.30612
Subtracting 98 from 110 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
49 can be fit into 120 2 times, resulting in a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 17344.306122
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.

The final outcome is 17344.306122, with a leftover of 2.2e-06.
