We look at the division of 72057126 by 407 
We want to divide 72057126 by 407.

Step 1:
407 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 407

Advancing to step 2:
When dividing 72 by 407, we get 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Take the next digit (0) from the dividend and append it to 72, then repeat: 720 / 407

Let's proceed to step 3:
407 can be fit into 720 1 times, resulting in a remainder of 313.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 407 from 720, we get 313.
Include the next digit (5) from the dividend after 313, then repeat: 3135 / 407

Moving on to step 4:
3135 divided by 407 is 7 with a remainder of 286.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 2849 from 3135 and we're left with 286.
Fetch the next digit (7) from the dividend, attach it to 286 and continue: 2867 / 407

Let's proceed to step 5:
407 goes into 2867 7 times with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 177.0
Subtract 2849 from 2867 to get 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 407

On to step 6:
If we divide 181 by 407, we get 0 and a remainder of 181.
Write down 0 as next digit of the result. 
Result so far: 1770.0
If we subtract 0 from 181, we get 181.
Bring next digit (2) of the dividend behind the 181 and repeat the process: 1812 / 407

Advancing to step 7:
407 goes into 1812 4 times with a remainder of 184.
Use 4 as the next digit of our solution. 
Result so far: 17704.0
Deduct 1628 from 1812 and we're left with 184.
Bring next digit (6) of the dividend behind the 184 and repeat the process: 1846 / 407

Step 8:
If we divide 1846 by 407, we get 4 and a remainder of 218.
Write down 4 as next digit of the result. 
Result so far: 177044.0
Subtract 1628 from 1846 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 9:
407 goes into 2180 5 times with a remainder of 145.
The next digit of our result is 5. 
Result so far: 177044.5
Subtract 2035 from 2180 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 10:
If we divide 1450 by 407, we get 3 and a remainder of 229.
Record the quotient 3 as the next digit in the result. 
Result so far: 177044.53
If we take 1221 away from 1450, we end up with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Advancing to step 11:
If we divide 2290 by 407, we get 5 and a remainder of 255.
Record the quotient 5 as the next digit in the result. 
Result so far: 177044.535
If we take 2035 away from 2290, we end up with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 12:
407 can be fit into 2550 6 times, resulting in a remainder of 108.
The number 6 becomes the next digit in our result. 
Result so far: 177044.5356
Deduct 2442 from 2550 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 13:
1080 divided by 407 is 2 with a remainder of 266.
Use 2 as the next digit of our solution. 
Result so far: 177044.53562
If we subtract 814 from 1080, we get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 14:
2660 divided by 407 is 6 with a remainder of 218.
Write down 6 as next digit of the result. 
Result so far: 177044.535626
If we take 2442 away from 2660, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 15:
The number 407 fits into 2180 5 times, leaving a remainder of 145.
The next digit of our result is 5. 
Result so far: 177044.5356265
The remainder is 145 after subtracting 2035 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 16:
If we divide 1450 by 407, we get 3 and a remainder of 229.
Use 3 as the next digit of our solution. 
Result so far: 177044.53562653
Deduct 1221 from 1450 and we're left with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Our division results in 177044.53562653 with a remaining 2.29e-07.
