We look at the division of 72401596 by 408 
We're looking to find how many times 408 goes into 72401596.

Going ahead to step 1:
408 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 408

Step 2:
408 can be fit into 72 0 times, resulting in a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Fetch the next digit (4) from the dividend, attach it to 72 and continue: 724 / 408

Step 3:
When dividing 724 by 408, we get 1 with a remainder of 316.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 408 from 724 and we're left with 316.
Bring next digit (0) of the dividend behind the 316 and repeat the process: 3160 / 408

Step 4:
When dividing 3160 by 408, we get 7 with a remainder of 304.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 2856 from 3160 to get 304.
Grab the next digit (1) from the dividend, add it to 304, then carry on: 3041 / 408

Advancing to step 5:
408 goes into 3041 7 times with a remainder of 185.
Write down 7 as next digit of the result. 
Result so far: 177.0
The remainder is 185 after subtracting 2856 from 3041.
Take the next digit (5) from the dividend and append it to 185, then repeat: 1855 / 408

Moving on to step 6:
If we divide 1855 by 408, we get 4 and a remainder of 223.
Write down 4 as next digit of the result. 
Result so far: 1774.0
Subtracting 1632 from 1855 leaves us with 223.
Fetch the next digit (9) from the dividend, attach it to 223 and continue: 2239 / 408

Going ahead to step 7:
If we divide 2239 by 408, we get 5 and a remainder of 199.
Put 5 as the next digit of the answer. 
Result so far: 17745.0
Subtracting 2040 from 2239 leaves us with 199.
Append the next digit (6) from the dividend to 199 and continue with: 1996 / 408

Let's proceed to step 8:
If we divide 1996 by 408, we get 4 and a remainder of 364.
Write down 4 as next digit of the result. 
Result so far: 177454.0
If we subtract 1632 from 1996, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 9:
When dividing 3640 by 408, we get 8 with a remainder of 376.
Write down 8 as next digit of the result. 
Result so far: 177454.8
If we take 3264 away from 3640, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 10:
408 goes into 3760 9 times with a remainder of 88.
The next digit of our result is 9. 
Result so far: 177454.89
Subtract 3672 from 3760 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 11:
408 goes into 880 2 times with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 177454.892
Deduct 816 from 880 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
When dividing 640 by 408, we get 1 with a remainder of 232.
Write down 1 as next digit of the result. 
Result so far: 177454.8921
Subtract 408 from 640 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 13:
If we divide 2320 by 408, we get 5 and a remainder of 280.
Use 5 as the next digit of our solution. 
Result so far: 177454.89215
The remainder is 280 after subtracting 2040 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 14:
If we divide 2800 by 408, we get 6 and a remainder of 352.
Use 6 as the next digit of our solution. 
Result so far: 177454.892156
Subtract 2448 from 2800 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 15:
The number 408 fits into 3520 8 times, leaving a remainder of 256.
Put 8 as the next digit of the answer. 
Result so far: 177454.8921568
Subtract 3264 from 3520 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 16:
408 can be fit into 2560 6 times, resulting in a remainder of 112.
The number 6 becomes the next digit in our result. 
Result so far: 177454.89215686
The remainder is 112 after subtracting 2448 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final result is 177454.89215686 with a remainder of 1.12e-07.
