51821 divided by 49 
Our goal is to divide 51821 by 49.

Going ahead to step 1:
49 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 49

On to step 2:
51 divided by 49 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
If we take 49 away from 51, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 49

On to step 3:
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: 10.0
If we subtract 0 from 28, we get 28.
Fetch the next digit (2) from the dividend, attach it to 28 and continue: 282 / 49

Moving on to step 4:
When dividing 282 by 49, we get 5 with a remainder of 37.
Use 5 as the next digit of our solution. 
Result so far: 105.0
If we take 245 away from 282, we end up with 37.
Include the next digit (1) from the dividend after 37, then repeat: 371 / 49

Moving on to step 5:
49 can be fit into 371 7 times, resulting in a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 1057.0
Subtracting 343 from 371 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 6:
280 divided by 49 is 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 1057.5
The remainder is 35 after subtracting 245 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 7:
49 goes into 350 7 times with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 1057.57
If we take 343 away from 350, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
70 divided by 49 is 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1057.571
If we subtract 49 from 70, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 9:
The number 49 fits into 210 4 times, leaving a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 1057.5714
Deduct 196 from 210 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
If we divide 140 by 49, we get 2 and a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 1057.57142
If we take 98 away from 140, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 11:
When dividing 420 by 49, we get 8 with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 1057.571428
If we take 392 away from 420, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 12:
49 can be fit into 280 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 1057.5714285
Subtract 245 from 280 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 13:
49 goes into 350 7 times with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 1057.57142857
If we take 343 away from 350, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 1057.57142857 with a remaining 7e-09.
