We look at the division of 12502560 by 408 
We're looking to find how many times 408 goes into 12502560.

Moving on to step 1:
408 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 408

Advancing to step 2:
If we divide 12 by 408, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 408

Step 3:
If we divide 125 by 408, we get 0 and a remainder of 125.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 125 leaves us with 125.
Fetch the next digit (0) from the dividend, attach it to 125 and continue: 1250 / 408

Advancing to step 4:
When dividing 1250 by 408, we get 3 with a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 1224 from 1250 and we're left with 26.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 408

Moving on to step 5:
408 can be fit into 262 0 times, resulting in a remainder of 262.
The next digit of our result is 0. 
Result so far: 30.0
Deduct 0 from 262 and we're left with 262.
Include the next digit (5) from the dividend after 262, then repeat: 2625 / 408

Going ahead to step 6:
The number 408 fits into 2625 6 times, leaving a remainder of 177.
Write down 6 as next digit of the result. 
Result so far: 306.0
Deduct 2448 from 2625 and we're left with 177.
Bring next digit (6) of the dividend behind the 177 and repeat the process: 1776 / 408

Step 7:
1776 divided by 408 is 4 with a remainder of 144.
Write down 4 as next digit of the result. 
Result so far: 3064.0
Deduct 1632 from 1776 and we're left with 144.
Include the next digit (0) from the dividend after 144, then repeat: 1440 / 408

Going ahead to step 8:
If we divide 1440 by 408, we get 3 and a remainder of 216.
Write down 3 as next digit of the result. 
Result so far: 30643.0
Subtracting 1224 from 1440 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 9:
The number 408 fits into 2160 5 times, leaving a remainder of 120.
Record the quotient 5 as the next digit in the result. 
Result so far: 30643.5
Deduct 2040 from 2160 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 10:
1200 divided by 408 is 2 with a remainder of 384.
The number 2 becomes the next digit in our result. 
Result so far: 30643.52
Deduct 816 from 1200 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 11:
408 can be fit into 3840 9 times, resulting in a remainder of 168.
The number 9 becomes the next digit in our result. 
Result so far: 30643.529
The remainder is 168 after subtracting 3672 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 12:
The number 408 fits into 1680 4 times, leaving a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 30643.5294
If we take 1632 away from 1680, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
480 divided by 408 is 1 with a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 30643.52941
If we take 408 away from 480, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 14:
720 divided by 408 is 1 with a remainder of 312.
Put 1 as the next digit of the answer. 
Result so far: 30643.529411
If we subtract 408 from 720, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The final outcome is 30643.529411, with a leftover of 3.12e-05.
