We look at the division of 671465 by 86 
We're looking to find how many times 86 goes into 671465.

On to step 1:
86 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 86

Step 2:
86 can be fit into 67 0 times, resulting in a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Grab the next digit (1) from the dividend, add it to 67, then carry on: 671 / 86

Advancing to step 3:
86 can be fit into 671 7 times, resulting in a remainder of 69.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 602 from 671 to get 69.
Take the next digit (4) from the dividend and append it to 69, then repeat: 694 / 86

Moving on to step 4:
694 divided by 86 is 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 78.0
If we take 688 away from 694, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 86

Advancing to step 5:
66 divided by 86 is 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 780.0
Deduct 0 from 66 and we're left with 66.
Fetch the next digit (5) from the dividend, attach it to 66 and continue: 665 / 86

Step 6:
If we divide 665 by 86, we get 7 and a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 7807.0
Subtracting 602 from 665 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 7:
The number 86 fits into 630 7 times, leaving a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 7807.7
Subtract 602 from 630 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
86 goes into 280 3 times with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 7807.73
If we take 258 away from 280, we end up 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.

Advancing to step 9:
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: 7807.732
Subtract 172 from 220 to 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.

Moving on to step 10:
When dividing 480 by 86, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 7807.7325
Subtract 430 from 480 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
86 goes into 500 5 times with a remainder of 70.
The next digit of our result is 5. 
Result so far: 7807.73255
Subtract 430 from 500 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 7807.73255 with a remaining 7e-05.
