We look at the division of 10179975 by 407 
Let's see how many times 407 fits into 10179975.

Let's proceed to step 1:
407 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 407

Going ahead to step 2:
The number 407 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 407

Advancing to step 3:
The number 407 fits into 101 0 times, leaving a remainder of 101.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 101 leaves us with 101.
Take the next digit (7) from the dividend and append it to 101, then repeat: 1017 / 407

Going ahead to step 4:
If we divide 1017 by 407, we get 2 and a remainder of 203.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 814 from 1017 to get 203.
Include the next digit (9) from the dividend after 203, then repeat: 2039 / 407

Advancing to step 5:
If we divide 2039 by 407, we get 5 and a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtract 2035 from 2039 to get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 407

Let's proceed to step 6:
407 can be fit into 49 0 times, resulting in a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 250.0
The remainder is 49 after subtracting 0 from 49.
Include the next digit (7) from the dividend after 49, then repeat: 497 / 407

Advancing to step 7:
497 divided by 407 is 1 with a remainder of 90.
Write down 1 as next digit of the result. 
Result so far: 2501.0
Deduct 407 from 497 and we're left with 90.
Grab the next digit (5) from the dividend, add it to 90, then carry on: 905 / 407

Step 8:
If we divide 905 by 407, we get 2 and a remainder of 91.
Put 2 as the next digit of the answer. 
Result so far: 25012.0
Subtracting 814 from 905 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 9:
When dividing 910 by 407, we get 2 with a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 25012.2
If we subtract 814 from 910, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 10:
407 can be fit into 960 2 times, resulting in a remainder of 146.
Write down 2 as next digit of the result. 
Result so far: 25012.22
If we take 814 away from 960, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

The final result is 25012.22 with a remainder of 0.146.
