53041409 ÷ 408 
We want to divide 53041409 by 408.

Let's proceed to step 1:
408 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 408

Let's proceed to step 2:
The number 408 fits into 53 0 times, leaving a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Fetch the next digit (0) from the dividend, attach it to 53 and continue: 530 / 408

Step 3:
408 goes into 530 1 times with a remainder of 122.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 408 from 530 and we're left with 122.
Fetch the next digit (4) from the dividend, attach it to 122 and continue: 1224 / 408

Let's proceed to step 4:
If we divide 1224 by 408, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 1224 from 1224, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 408

Let's proceed to step 5:
408 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 130.0
If we subtract 0 from 1, we get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 408

Advancing to step 6:
408 can be fit into 14 0 times, resulting in a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 1300.0
Subtract 0 from 14 to get 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 408

On to step 7:
If we divide 140 by 408, we get 0 and a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 13000.0
If we take 0 away from 140, we end up with 140.
Include the next digit (9) from the dividend after 140, then repeat: 1409 / 408

Going ahead to step 8:
The number 408 fits into 1409 3 times, leaving a remainder of 185.
Put 3 as the next digit of the answer. 
Result so far: 130003.0
If we subtract 1224 from 1409, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 9:
The number 408 fits into 1850 4 times, leaving a remainder of 218.
Use 4 as the next digit of our solution. 
Result so far: 130003.4
Subtracting 1632 from 1850 leaves us 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.

Moving on to step 10:
408 goes into 2180 5 times with a remainder of 140.
Put 5 as the next digit of the answer. 
Result so far: 130003.45
Subtracting 2040 from 2180 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 11:
1400 divided by 408 is 3 with a remainder of 176.
Record the quotient 3 as the next digit in the result. 
Result so far: 130003.453
Deduct 1224 from 1400 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 12:
408 can be fit into 1760 4 times, resulting in a remainder of 128.
Write down 4 as next digit of the result. 
Result so far: 130003.4534
The remainder is 128 after subtracting 1632 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 13:
408 can be fit into 1280 3 times, resulting in a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 130003.45343
Deduct 1224 from 1280 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 14:
560 divided by 408 is 1 with a remainder of 152.
The next digit of our result is 1. 
Result so far: 130003.453431
Subtracting 408 from 560 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 15:
The number 408 fits into 1520 3 times, leaving a remainder of 296.
The next digit of our result is 3. 
Result so far: 130003.4534313
If we subtract 1224 from 1520, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 16:
408 goes into 2960 7 times with a remainder of 104.
The next digit of our result is 7. 
Result so far: 130003.45343137
Subtract 2856 from 2960 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

In conclusion, the division gives 130003.45343137 with a balance of 1.04e-07.
