672446 divided by 86 
We want to figure out the number of times 672446 can be divided by 86.

Advancing 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
Subtracting 0 from 6 leaves us with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 86

Moving on to step 2:
The number 86 fits into 67 0 times, leaving a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Take the next digit (2) from the dividend and append it to 67, then repeat: 672 / 86

On to step 3:
672 divided by 86 is 7 with a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 602 from 672 leaves us with 70.
Append the next digit (4) from the dividend to 70 and continue with: 704 / 86

Let's proceed to step 4:
When dividing 704 by 86, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Subtract 688 from 704 to get 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 86

Let's proceed to step 5:
86 goes into 164 1 times with a remainder of 78.
The next digit of our result is 1. 
Result so far: 781.0
If we take 86 away from 164, we end up with 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 86

Let's proceed to step 6:
If we divide 786 by 86, we get 9 and a remainder of 12.
The next digit of our result is 9. 
Result so far: 7819.0
The remainder is 12 after subtracting 774 from 786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
86 goes into 120 1 times with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 7819.1
If we take 86 away from 120, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
If we divide 340 by 86, we get 3 and a remainder of 82.
The next digit of our result is 3. 
Result so far: 7819.13
If we subtract 258 from 340, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 9:
86 goes into 820 9 times with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 7819.139
Subtract 774 from 820 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 10:
86 goes into 460 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 7819.1395
If we subtract 430 from 460, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
When dividing 300 by 86, we get 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 7819.13953
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
420 divided by 86 is 4 with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 7819.139534
If we take 344 away from 420, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 13:
760 divided by 86 is 8 with a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 7819.1395348
Subtract 688 from 760 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 14:
When dividing 720 by 86, we get 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 7819.13953488
The remainder is 32 after subtracting 688 from 720.
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 outcome is 7819.13953488, with a leftover of 3.2e-08.
