We look at the division of 686124 by 49 
We want to divide 686124 by 49.

Let's proceed to step 1:
If we divide 6 by 49, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 49

Moving on to step 2:
49 goes into 68 1 times with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 49 from 68, we get 19.
Include the next digit (6) from the dividend after 19, then repeat: 196 / 49

Let's proceed to step 3:
196 divided by 49 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 196 from 196 and we're left with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 49

Step 4:
49 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 140.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 49

On to step 5:
When dividing 12 by 49, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 1400.0
Subtract 0 from 12 to get 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 49

Going ahead to step 6:
When dividing 124 by 49, we get 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 14002.0
Deduct 98 from 124 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
If we divide 260 by 49, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 14002.5
If we take 245 away from 260, we end up 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.

On to step 8:
150 divided by 49 is 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 14002.53
If we subtract 147 from 150, we 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.

Advancing to step 9:
49 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 14002.53
Deduct 0 from 30 and we're left 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 10:
300 divided by 49 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 14002.5306
If we take 294 away from 300, we end up with 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 11:
If we divide 60 by 49, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 14002.53061
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.

Moving on to step 12:
49 can be fit into 110 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 14002.530612
If we subtract 98 from 110, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
49 goes into 120 2 times with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 14002.5306122
Deduct 98 from 120 and we're left 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 quotient of the division is 14002.5306122, and the remainder is 2.2e-07.
