We're dividing 7886047 by 485 
We want to figure out the number of times 7886047 can be divided by 485.

Let's proceed to step 1:
If we divide 7 by 485, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 485

Let's proceed to step 2:
If we divide 78 by 485, we get 0 and a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Fetch the next digit (8) from the dividend, attach it to 78 and continue: 788 / 485

Let's proceed to step 3:
788 divided by 485 is 1 with a remainder of 303.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 485 from 788, we get 303.
Append the next digit (6) from the dividend to 303 and continue with: 3036 / 485

On to step 4:
If we divide 3036 by 485, we get 6 and a remainder of 126.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 2910 from 3036 and we're left with 126.
Append the next digit (0) from the dividend to 126 and continue with: 1260 / 485

Step 5:
If we divide 1260 by 485, we get 2 and a remainder of 290.
Record the quotient 2 as the next digit in the result. 
Result so far: 162.0
The remainder is 290 after subtracting 970 from 1260.
Fetch the next digit (4) from the dividend, attach it to 290 and continue: 2904 / 485

Moving on to step 6:
485 can be fit into 2904 5 times, resulting in a remainder of 479.
The number 5 becomes the next digit in our result. 
Result so far: 1625.0
Subtracting 2425 from 2904 leaves us with 479.
Bring next digit (7) of the dividend behind the 479 and repeat the process: 4797 / 485

On to step 7:
4797 divided by 485 is 9 with a remainder of 432.
The next digit of our result is 9. 
Result so far: 16259.0
Subtract 4365 from 4797 to get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Going ahead to step 8:
485 can be fit into 4320 8 times, resulting in a remainder of 440.
The next digit of our result is 8. 
Result so far: 16259.8
If we take 3880 away from 4320, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 9:
4400 divided by 485 is 9 with a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 16259.89
Subtracting 4365 from 4400 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 10:
The number 485 fits into 350 0 times, leaving a remainder of 350.
The next digit of our result is 0. 
Result so far: 16259.89
Subtract 0 from 350 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 11:
485 goes into 3500 7 times with a remainder of 105.
Record the quotient 7 as the next digit in the result. 
Result so far: 16259.8907
Subtract 3395 from 3500 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 12:
If we divide 1050 by 485, we get 2 and a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 16259.89072
Subtract 970 from 1050 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
The number 485 fits into 800 1 times, leaving a remainder of 315.
The number 1 becomes the next digit in our result. 
Result so far: 16259.890721
Deduct 485 from 800 and we're left with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

On to step 14:
The number 485 fits into 3150 6 times, leaving a remainder of 240.
Record the quotient 6 as the next digit in the result. 
Result so far: 16259.8907216
Subtracting 2910 from 3150 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 15:
485 can be fit into 2400 4 times, resulting in a remainder of 460.
Put 4 as the next digit of the answer. 
Result so far: 16259.89072164
If we subtract 1940 from 2400, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

The final outcome is 16259.89072164, with a leftover of 4.6e-07.
