Write down 5 as next digit of the result. 
Result so far: 105.0
Subtract 3430 from 3739 to get 309.
Append the next digit (7) from the dividend to 309 and continue with: 3097 / 686

Moving on to step 6:
686 goes into 3097 4 times with a remainder of 353.
Put 4 as the next digit of the answer. 
Result so far: 1054.0
If we subtract 2744 from 3097, we get 353.
Fetch the next digit (2) from the dividend, attach it to 353 and continue: 3532 / 686

Let's proceed to step 7:
When dividing 3532 by 686, we get 5 with a remainder of 102.
The next digit of our result is 5. 
Result so far: 10545.0
Subtract 3430 from 3532 to get 102.
Take the next digit (6) from the dividend and append it to 102, then repeat: 1026 / 686

Going ahead to step 8:
If we divide 1026 by 686, we get 1 and a remainder of 340.
The number 1 becomes the next digit in our result. 
Result so far: 105451.0
Subtract 686 from 1026 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 9:
686 goes into 3400 4 times with a remainder of 656.
Put 4 as the next digit of the answer. 
Result so far: 105451.4
Subtract 2744 from 3400 to get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Let's proceed to step 10:
When dividing 6560 by 686, we get 9 with a remainder of 386.
The number 9 becomes the next digit in our result. 
Result so far: 105451.49
Deduct 6174 from 6560 and we're left with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Moving on to step 11:
3860 divided by 686 is 5 with a remainder of 430.
Put 5 as the next digit of the answer. 
Result so far: 105451.495
If we subtract 3430 from 3860, we get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 12:
4300 divided by 686 is 6 with a remainder of 184.
The next digit of our result is 6. 
Result so far: 105451.4956
The remainder is 184 after subtracting 4116 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 13:
If we divide 1840 by 686, we get 2 and a remainder of 468.
Record the quotient 2 as the next digit in the result. 
Result so far: 105451.49562
Deduct 1372 from 1840 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

On to step 14:
If we divide 4680 by 686, we get 6 and a remainder of 564.
The next digit of our result is 6. 
Result so far: 105451.495626
If we take 4116 away from 4680, we end up with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Step 15:
686 goes into 5640 8 times with a remainder of 152.
The next digit of our result is 8. 
Result so far: 105451.4956268
The remainder is 152 after subtracting 5488 from 5640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 16:
The number 686 fits into 1520 2 times, leaving a remainder of 148.
Put 2 as the next digit of the answer. 
Result so far: 105451.49562682
Deduct 1372 from 1520 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

After the division, we end up with 105451.49562682 and a remainder of 1.48e-07.
