We're dividing 42595400 by 407 
We're looking to find how many times 407 goes into 42595400.

On to step 1:
The number 407 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 407

Going ahead to step 2:
407 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 407

Step 3:
The number 407 fits into 425 1 times, leaving a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 407 from 425 to get 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 407

Advancing to step 4:
189 divided by 407 is 0 with a remainder of 189.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 189 leaves us with 189.
Bring next digit (5) of the dividend behind the 189 and repeat the process: 1895 / 407

Advancing to step 5:
When dividing 1895 by 407, we get 4 with a remainder of 267.
The next digit of our result is 4. 
Result so far: 104.0
Subtract 1628 from 1895 to get 267.
Append the next digit (4) from the dividend to 267 and continue with: 2674 / 407

On to step 6:
If we divide 2674 by 407, we get 6 and a remainder of 232.
Put 6 as the next digit of the answer. 
Result so far: 1046.0
Deduct 2442 from 2674 and we're left with 232.
Bring next digit (0) of the dividend behind the 232 and repeat the process: 2320 / 407

Moving on to step 7:
407 goes into 2320 5 times with a remainder of 285.
The next digit of our result is 5. 
Result so far: 10465.0
If we subtract 2035 from 2320, we get 285.
Include the next digit (0) from the dividend after 285, then repeat: 2850 / 407

Step 8:
407 goes into 2850 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 104657.0
Deduct 2849 from 2850 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
407 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 104657.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
100 divided by 407 is 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 104657.0
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 104657.0, with a leftover of 0.1.
