We look at the division of 79503728 by 407 
Let's see how many times 407 fits into 79503728.

Let's proceed to step 1:
407 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 407

Going ahead to step 2:
407 can be fit into 79 0 times, resulting in a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Bring next digit (5) of the dividend behind the 79 and repeat the process: 795 / 407

On to step 3:
The number 407 fits into 795 1 times, leaving a remainder of 388.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 407 from 795, we get 388.
Include the next digit (0) from the dividend after 388, then repeat: 3880 / 407

Moving on to step 4:
3880 divided by 407 is 9 with a remainder of 217.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 3663 from 3880 leaves us with 217.
Bring next digit (3) of the dividend behind the 217 and repeat the process: 2173 / 407

Moving on to step 5:
When dividing 2173 by 407, we get 5 with a remainder of 138.
The number 5 becomes the next digit in our result. 
Result so far: 195.0
If we subtract 2035 from 2173, we get 138.
Take the next digit (7) from the dividend and append it to 138, then repeat: 1387 / 407

Moving on to step 6:
1387 divided by 407 is 3 with a remainder of 166.
The number 3 becomes the next digit in our result. 
Result so far: 1953.0
If we subtract 1221 from 1387, we get 166.
Append the next digit (2) from the dividend to 166 and continue with: 1662 / 407

Advancing to step 7:
407 goes into 1662 4 times with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 19534.0
Subtract 1628 from 1662 to get 34.
Include the next digit (8) from the dividend after 34, then repeat: 348 / 407

Moving on to step 8:
407 can be fit into 348 0 times, resulting in a remainder of 348.
Use 0 as the next digit of our solution. 
Result so far: 195340.0
Deduct 0 from 348 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Step 9:
The number 407 fits into 3480 8 times, leaving a remainder of 224.
Put 8 as the next digit of the answer. 
Result so far: 195340.8
Subtract 3256 from 3480 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 10:
407 goes into 2240 5 times with a remainder of 205.
Record the quotient 5 as the next digit in the result. 
Result so far: 195340.85
If we subtract 2035 from 2240, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 11:
When dividing 2050 by 407, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 195340.855
If we take 2035 away from 2050, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 195340.855, and the remainder is 0.0015.
