672448 divided by 86 
We want to divide 672448 by 86.

Going ahead 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 subtract 0 from 6, we get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 86

Step 2:
When dividing 67 by 86, we get 0 with a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Append the next digit (2) from the dividend to 67 and continue with: 672 / 86

Step 3:
86 can be fit into 672 7 times, resulting in a remainder of 70.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 602 from 672, we get 70.
Include the next digit (4) from the dividend after 70, then repeat: 704 / 86

Step 4:
If we divide 704 by 86, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 78.0
Subtract 688 from 704 to get 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 86

Let's proceed to step 5:
86 goes into 164 1 times with a remainder of 78.
The number 1 becomes the next digit in our result. 
Result so far: 781.0
If we subtract 86 from 164, we get 78.
Include the next digit (8) from the dividend after 78, then repeat: 788 / 86

On to step 6:
86 goes into 788 9 times with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 7819.0
Subtracting 774 from 788 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
The number 86 fits into 140 1 times, leaving a remainder of 54.
The next digit of our result is 1. 
Result so far: 7819.1
Deduct 86 from 140 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 8:
86 can be fit into 540 6 times, resulting in a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 7819.16
Deduct 516 from 540 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
The number 86 fits into 240 2 times, leaving a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 7819.162
Subtracting 172 from 240 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 10:
680 divided by 86 is 7 with a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 7819.1627
If we take 602 away from 680, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 11:
When dividing 780 by 86, we get 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 7819.16279
If we take 774 away from 780, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
60 divided by 86 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 7819.16279
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 13:
86 can be fit into 600 6 times, resulting in a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 7819.1627906
The remainder is 84 after subtracting 516 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 14:
If we divide 840 by 86, we get 9 and a remainder of 66.
The next digit of our result is 9. 
Result so far: 7819.16279069
If we subtract 774 from 840, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final result is 7819.16279069 with a remainder of 6.6e-08.
