34397695 ÷ 686 
Let's see how many times 686 fits into 34397695.

Step 1:
When dividing 3 by 686, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 686

Advancing to step 2:
If we divide 34 by 686, we get 0 and a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Take the next digit (3) from the dividend and append it to 34, then repeat: 343 / 686

Step 3:
The number 686 fits into 343 0 times, leaving a remainder of 343.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 343 and we're left with 343.
Take the next digit (9) from the dividend and append it to 343, then repeat: 3439 / 686

Going ahead to step 4:
3439 divided by 686 is 5 with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 3430 from 3439, we get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 686

Moving on to step 5:
686 can be fit into 97 0 times, resulting in a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 50.0
The remainder is 97 after subtracting 0 from 97.
Append the next digit (6) from the dividend to 97 and continue with: 976 / 686

Let's proceed to step 6:
686 can be fit into 976 1 times, resulting in a remainder of 290.
The next digit of our result is 1. 
Result so far: 501.0
If we subtract 686 from 976, we get 290.
Append the next digit (9) from the dividend to 290 and continue with: 2909 / 686

Going ahead to step 7:
2909 divided by 686 is 4 with a remainder of 165.
The number 4 becomes the next digit in our result. 
Result so far: 5014.0
If we subtract 2744 from 2909, we get 165.
Bring next digit (5) of the dividend behind the 165 and repeat the process: 1655 / 686

Moving on to step 8:
The number 686 fits into 1655 2 times, leaving a remainder of 283.
The number 2 becomes the next digit in our result. 
Result so far: 50142.0
Subtracting 1372 from 1655 leaves us with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

On to step 9:
The number 686 fits into 2830 4 times, leaving a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 50142.4
If we take 2744 away from 2830, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 10:
860 divided by 686 is 1 with a remainder of 174.
Record the quotient 1 as the next digit in the result. 
Result so far: 50142.41
Deduct 686 from 860 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 11:
If we divide 1740 by 686, we get 2 and a remainder of 368.
Write down 2 as next digit of the result. 
Result so far: 50142.412
If we subtract 1372 from 1740, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 12:
If we divide 3680 by 686, we get 5 and a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 50142.4125
Deduct 3430 from 3680 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 13:
When dividing 2500 by 686, we get 3 with a remainder of 442.
Use 3 as the next digit of our solution. 
Result so far: 50142.41253
Subtract 2058 from 2500 to get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Let's proceed to step 14:
When dividing 4420 by 686, we get 6 with a remainder of 304.
Write down 6 as next digit of the result. 
Result so far: 50142.412536
Deduct 4116 from 4420 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 15:
686 goes into 3040 4 times with a remainder of 296.
The next digit of our result is 4. 
Result so far: 50142.4125364
Deduct 2744 from 3040 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 16:
686 goes into 2960 4 times with a remainder of 216.
Put 4 as the next digit of the answer. 
Result so far: 50142.41253644
If we take 2744 away from 2960, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

After the division, we end up with 50142.41253644 and a remainder of 2.16e-07.
