674664 divided by 86 
Let's see how many times 86 fits into 674664.

Advancing to step 1:
86 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 86

Moving on to step 2:
The number 86 fits into 67 0 times, leaving a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Include the next digit (4) from the dividend after 67, then repeat: 674 / 86

Let's proceed to step 3:
674 divided by 86 is 7 with a remainder of 72.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 602 from 674 to get 72.
Take the next digit (6) from the dividend and append it to 72, then repeat: 726 / 86

Going ahead to step 4:
When dividing 726 by 86, we get 8 with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 78.0
If we take 688 away from 726, we end up with 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 86

On to step 5:
If we divide 386 by 86, we get 4 and a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 784.0
Deduct 344 from 386 and we're left with 42.
Fetch the next digit (4) from the dividend, attach it to 42 and continue: 424 / 86

Moving on to step 6:
86 can be fit into 424 4 times, resulting in a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 7844.0
The remainder is 80 after subtracting 344 from 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 7:
The number 86 fits into 800 9 times, leaving a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 7844.9
If we subtract 774 from 800, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
The number 86 fits into 260 3 times, leaving a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 7844.93
Deduct 258 from 260 and we're left 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.

On to step 9:
The number 86 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 7844.93
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.
Put 2 as the next digit of the answer. 
Result so far: 7844.9302
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 next digit of our result is 3. 
Result so far: 7844.93023
Deduct 258 from 280 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
220 divided by 86 is 2 with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 7844.930232
If we subtract 172 from 220, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 13:
When dividing 480 by 86, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 7844.9302325
Deduct 430 from 480 and we're left 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.

On to step 14:
500 divided by 86 is 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 7844.93023255
The remainder is 70 after subtracting 430 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 7844.93023255 and a remainder of 7e-08.
