686894 ÷ 49 
We want to divide 686894 by 49.

Going ahead to step 1:
49 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 49

Advancing to step 2:
49 goes into 68 1 times with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 49 from 68 and we're left with 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 49

On to step 3:
49 goes into 196 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 196 from 196 and we're left with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 49

Moving on to step 4:
49 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 140.0
Subtract 0 from 8 to get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 49

Advancing to step 5:
When dividing 89 by 49, we get 1 with a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 1401.0
Subtracting 49 from 89 leaves us with 40.
Append the next digit (4) from the dividend to 40 and continue with: 404 / 49

Going ahead to step 6:
If we divide 404 by 49, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 14018.0
Deduct 392 from 404 and we're left 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.

Advancing to step 7:
120 divided by 49 is 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 14018.2
If we take 98 away from 120, we end up 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.

Going ahead to step 8:
When dividing 220 by 49, we get 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 14018.24
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.

Let's proceed to step 9:
If we divide 240 by 49, we get 4 and a remainder of 44.
The next digit of our result is 4. 
Result so far: 14018.244
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.

Our division results in 14018.244 with a remaining 0.0044.
