We're dividing 686406 by 49 
We want to figure out the number of times 686406 can be divided by 49.

Let's proceed to step 1:
The number 49 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 49

On to step 2:
49 can be fit into 68 1 times, resulting in a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 49 from 68 to get 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 49

Let's proceed to step 3:
When dividing 196 by 49, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 196 away from 196, we end up with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 49

Advancing to step 4:
The number 49 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 140.0
Subtract 0 from 4 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 49

Advancing to step 5:
The number 49 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 1400.0
Deduct 0 from 40 and we're left with 40.
Take the next digit (6) from the dividend and append it to 40, then repeat: 406 / 49

Let's proceed to step 6:
If we divide 406 by 49, we get 8 and a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 14008.0
Deduct 392 from 406 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.

Advancing to step 7:
If we divide 140 by 49, we get 2 and a remainder of 42.
The next digit of our result is 2. 
Result so far: 14008.2
The remainder is 42 after subtracting 98 from 140.
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 8:
420 divided by 49 is 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 14008.28
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 9:
49 goes into 280 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 14008.285
If we take 245 away from 280, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
If we divide 350 by 49, we get 7 and a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 14008.2857
Subtracting 343 from 350 leaves us 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.

Let's proceed to step 11:
70 divided by 49 is 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 14008.28571
If we take 49 away from 70, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 12:
49 goes into 210 4 times with a remainder of 14.
The next digit of our result is 4. 
Result so far: 14008.285714
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.

Moving on to step 13:
49 goes into 140 2 times with a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 14008.2857142
If we subtract 98 from 140, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 14:
When dividing 420 by 49, we get 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 14008.28571428
Subtracting 392 from 420 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.

The quotient of the division is 14008.28571428, and the remainder is 2.8e-08.
