100857 ÷ 49 
We want to divide 100857 by 49.

Going ahead to step 1:
The number 49 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 49

On to step 2:
49 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 49

Advancing to step 3:
49 goes into 100 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 98 from 100 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 49

On to step 4:
If we divide 28 by 49, we get 0 and a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtracting 0 from 28 leaves us with 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 49

Moving on to step 5:
49 can be fit into 285 5 times, resulting in a remainder of 40.
The next digit of our result is 5. 
Result so far: 205.0
Subtract 245 from 285 to get 40.
Append the next digit (7) from the dividend to 40 and continue with: 407 / 49

Moving on to step 6:
The number 49 fits into 407 8 times, leaving a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 2058.0
The remainder is 15 after subtracting 392 from 407.
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:
The number 49 fits into 150 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 2058.3
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 8:
30 divided by 49 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 2058.3
If we subtract 0 from 30, we 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.

Going ahead to step 9:
49 can be fit into 300 6 times, resulting in a remainder of 6.
The next digit of our result is 6. 
Result so far: 2058.306
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.

Step 10:
60 divided by 49 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 2058.3061
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.

Let's proceed to step 11:
When dividing 110 by 49, we get 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 2058.30612
If we take 98 away from 110, we end up 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:
When dividing 120 by 49, we get 2 with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 2058.306122
If we subtract 98 from 120, we 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 2058.306122 with a remainder of 2.2e-06.
