89763434 divided by 686 
Let's see how many times 686 fits into 89763434.

Let's proceed to step 1:
If we divide 8 by 686, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 686

On to step 2:
686 goes into 89 0 times with a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Bring next digit (7) of the dividend behind the 89 and repeat the process: 897 / 686

Step 3:
686 can be fit into 897 1 times, resulting in a remainder of 211.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 686 from 897 to get 211.
Fetch the next digit (6) from the dividend, attach it to 211 and continue: 2116 / 686

Moving on to step 4:
When dividing 2116 by 686, we get 3 with a remainder of 58.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 58 after subtracting 2058 from 2116.
Append the next digit (3) from the dividend to 58 and continue with: 583 / 686

Moving on to step 5:
686 goes into 583 0 times with a remainder of 583.
The number 0 becomes the next digit in our result. 
Result so far: 130.0
The remainder is 583 after subtracting 0 from 583.
Grab the next digit (4) from the dividend, add it to 583, then carry on: 5834 / 686

Advancing to step 6:
686 goes into 5834 8 times with a remainder of 346.
The next digit of our result is 8. 
Result so far: 1308.0
Subtract 5488 from 5834 to get 346.
Bring next digit (3) of the dividend behind the 346 and repeat the process: 3463 / 686

On to step 7:
The number 686 fits into 3463 5 times, leaving a remainder of 33.
The next digit of our result is 5. 
Result so far: 13085.0
Deduct 3430 from 3463 and we're left with 33.
Include the next digit (4) from the dividend after 33, then repeat: 334 / 686

Going ahead to step 8:
If we divide 334 by 686, we get 0 and a remainder of 334.
Record the quotient 0 as the next digit in the result. 
Result so far: 130850.0
If we take 0 away from 334, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 9:
If we divide 3340 by 686, we get 4 and a remainder of 596.
Use 4 as the next digit of our solution. 
Result so far: 130850.4
Subtract 2744 from 3340 to get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

On to step 10:
When dividing 5960 by 686, we get 8 with a remainder of 472.
Write down 8 as next digit of the result. 
Result so far: 130850.48
Deduct 5488 from 5960 and we're left with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Going ahead to step 11:
686 can be fit into 4720 6 times, resulting in a remainder of 604.
The number 6 becomes the next digit in our result. 
Result so far: 130850.486
Subtracting 4116 from 4720 leaves us with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Let's proceed to step 12:
6040 divided by 686 is 8 with a remainder of 552.
Use 8 as the next digit of our solution. 
Result so far: 130850.4868
If we take 5488 away from 6040, we end up with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

On to step 13:
If we divide 5520 by 686, we get 8 and a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 130850.48688
Subtract 5488 from 5520 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 130850.48688 with a remainder of 3.2e-05.
