683608 ÷ 86 
We want to figure out the number of times 683608 can be divided by 86.

Advancing to step 1:
6 divided by 86 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 86

Step 2:
68 divided by 86 is 0 with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Take the next digit (3) from the dividend and append it to 68, then repeat: 683 / 86

Going ahead to step 3:
When dividing 683 by 86, we get 7 with a remainder of 81.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 602 from 683 and we're left with 81.
Fetch the next digit (6) from the dividend, attach it to 81 and continue: 816 / 86

Going ahead to step 4:
If we divide 816 by 86, we get 9 and a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
Subtract 774 from 816 to get 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 86

Moving on to step 5:
420 divided by 86 is 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 794.0
If we take 344 away from 420, we end up with 76.
Fetch the next digit (8) from the dividend, attach it to 76 and continue: 768 / 86

On to step 6:
86 can be fit into 768 8 times, resulting in a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 7948.0
Subtracting 688 from 768 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 7:
The number 86 fits into 800 9 times, leaving a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 7948.9
If we take 774 away from 800, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
If we divide 260 by 86, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 7948.93
If we take 258 away from 260, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
86 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 7948.93
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
200 divided by 86 is 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 7948.9302
If we take 172 away from 200, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
86 goes into 280 3 times with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 7948.93023
Subtract 258 from 280 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
86 can be fit into 220 2 times, resulting in a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 7948.930232
Deduct 172 from 220 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 13:
86 can be fit into 480 5 times, resulting in a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 7948.9302325
If we take 430 away from 480, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 14:
86 can be fit into 500 5 times, resulting in a remainder of 70.
The next digit of our result is 5. 
Result so far: 7948.93023255
Subtracting 430 from 500 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 7948.93023255 with a remainder of 7e-08.
