686087 ÷ 34 
We want to divide 686087 by 34.

On to step 1:
34 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
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 34

Advancing to step 2:
If we divide 68 by 34, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 68 from 68 to get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 34

Going ahead to step 3:
When dividing 6 by 34, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 34

Moving on to step 4:
If we divide 60 by 34, we get 1 and a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 201.0
Subtracting 34 from 60 leaves us with 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 34

Moving on to step 5:
The number 34 fits into 268 7 times, leaving a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 2017.0
Subtracting 238 from 268 leaves us with 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 34

Going ahead to step 6:
34 goes into 307 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 20179.0
If we subtract 306 from 307, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
10 divided by 34 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 20179.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 34, we get 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 20179.02
Subtracting 68 from 100 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
34 goes into 320 9 times with a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 20179.029
If we subtract 306 from 320, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
140 divided by 34 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 20179.0294
Deduct 136 from 140 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
When dividing 40 by 34, we get 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 20179.02941
Deduct 34 from 40 and we're left 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.

Advancing to step 12:
34 goes into 60 1 times with a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 20179.029411
Subtract 34 from 60 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 20179.029411, with a leftover of 2.6e-06.
