91830823 ÷ 686 
We're looking to find how many times 686 goes into 91830823.

Let's proceed to step 1:
9 divided by 686 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 686

On to step 2:
91 divided by 686 is 0 with a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Append the next digit (8) from the dividend to 91 and continue with: 918 / 686

Advancing to step 3:
The number 686 fits into 918 1 times, leaving a remainder of 232.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 686 away from 918, we end up with 232.
Grab the next digit (3) from the dividend, add it to 232, then carry on: 2323 / 686

Advancing to step 4:
The number 686 fits into 2323 3 times, leaving a remainder of 265.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 2058 from 2323 and we're left with 265.
Include the next digit (0) from the dividend after 265, then repeat: 2650 / 686

On to step 5:
If we divide 2650 by 686, we get 3 and a remainder of 592.
Use 3 as the next digit of our solution. 
Result so far: 133.0
Subtracting 2058 from 2650 leaves us with 592.
Bring next digit (8) of the dividend behind the 592 and repeat the process: 5928 / 686

Step 6:
The number 686 fits into 5928 8 times, leaving a remainder of 440.
The next digit of our result is 8. 
Result so far: 1338.0
Subtract 5488 from 5928 to get 440.
Bring next digit (2) of the dividend behind the 440 and repeat the process: 4402 / 686

Going ahead to step 7:
686 goes into 4402 6 times with a remainder of 286.
Record the quotient 6 as the next digit in the result. 
Result so far: 13386.0
The remainder is 286 after subtracting 4116 from 4402.
Include the next digit (3) from the dividend after 286, then repeat: 2863 / 686

Let's proceed to step 8:
The number 686 fits into 2863 4 times, leaving a remainder of 119.
Use 4 as the next digit of our solution. 
Result so far: 133864.0
Subtract 2744 from 2863 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 9:
The number 686 fits into 1190 1 times, leaving a remainder of 504.
Put 1 as the next digit of the answer. 
Result so far: 133864.1
If we subtract 686 from 1190, we get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Going ahead to step 10:
The number 686 fits into 5040 7 times, leaving a remainder of 238.
The next digit of our result is 7. 
Result so far: 133864.17
Deduct 4802 from 5040 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 11:
If we divide 2380 by 686, we get 3 and a remainder of 322.
Use 3 as the next digit of our solution. 
Result so far: 133864.173
If we take 2058 away from 2380, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 12:
3220 divided by 686 is 4 with a remainder of 476.
The next digit of our result is 4. 
Result so far: 133864.1734
If we take 2744 away from 3220, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 13:
If we divide 4760 by 686, we get 6 and a remainder of 644.
Put 6 as the next digit of the answer. 
Result so far: 133864.17346
Subtracting 4116 from 4760 leaves us with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Let's proceed to step 14:
The number 686 fits into 6440 9 times, leaving a remainder of 266.
Use 9 as the next digit of our solution. 
Result so far: 133864.173469
The remainder is 266 after subtracting 6174 from 6440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Let's proceed to step 15:
If we divide 2660 by 686, we get 3 and a remainder of 602.
Record the quotient 3 as the next digit in the result. 
Result so far: 133864.1734693
If we take 2058 away from 2660, we end up with 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Moving on to step 16:
686 can be fit into 6020 8 times, resulting in a remainder of 532.
The next digit of our result is 8. 
Result so far: 133864.17346938
The remainder is 532 after subtracting 5488 from 6020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Our division results in 133864.17346938 with a remaining 5.32e-07.
