We're dividing 86447480 by 14 
Let's see how many times 14 fits into 86447480.

Step 1:
If we divide 8 by 14, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 14

On to step 2:
14 can be fit into 86 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 6.0
If we take 84 away from 86, we end up with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 14

Step 3:
14 goes into 24 1 times with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
Subtract 14 from 24 to get 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 14

On to step 4:
When dividing 104 by 14, we get 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 617.0
Deduct 98 from 104 and we're left with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 14

On to step 5:
67 divided by 14 is 4 with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 6174.0
If we take 56 away from 67, we end up with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 14

Advancing to step 6:
The number 14 fits into 114 8 times, leaving a remainder of 2.
The next digit of our result is 8. 
Result so far: 61748.0
Subtracting 112 from 114 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 14

Step 7:
If we divide 28 by 14, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 617482.0
Subtracting 28 from 28 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 14

Step 8:
The number 14 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 6174820.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
The number 14 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6174820.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
If we divide 0 by 14, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6174820.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 6174820.0 with a remainder of 0.0.
