Let's divide 53538008 by 409
We want to figure out the number of times 53538008 can be divided by 409.

On to step 1:
The number 409 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 409

Moving on to step 2:
The number 409 fits into 53 0 times, leaving a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Grab the next digit (5) from the dividend, add it to 53, then carry on: 535 / 409

Going ahead to step 3:
535 divided by 409 is 1 with a remainder of 126.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 126 after subtracting 409 from 535.
Bring next digit (3) of the dividend behind the 126 and repeat the process: 1263 / 409

On to step 4:
When dividing 1263 by 409, we get 3 with a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 1227 away from 1263, we end up with 36.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 409

Going ahead to step 5:
If we divide 368 by 409, we get 0 and a remainder of 368.
Put 0 as the next digit of the answer. 
Result so far: 130.0
Subtracting 0 from 368 leaves us with 368.
Include the next digit (0) from the dividend after 368, then repeat: 3680 / 409

Step 6:
409 goes into 3680 8 times with a remainder of 408.
Use 8 as the next digit of our solution. 
Result so far: 1308.0
Deduct 3272 from 3680 and we're left with 408.
Include the next digit (0) from the dividend after 408, then repeat: 4080 / 409

Going ahead to step 7:
When dividing 4080 by 409, we get 9 with a remainder of 399.
Use 9 as the next digit of our solution. 
Result so far: 13089.0
If we subtract 3681 from 4080, we get 399.
Bring next digit (8) of the dividend behind the 399 and repeat the process: 3998 / 409

Let's proceed to step 8:
409 goes into 3998 9 times with a remainder of 317.
Write down 9 as next digit of the result. 
Result so far: 130899.0
Subtract 3681 from 3998 to get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Let's proceed to step 9:
3170 divided by 409 is 7 with a remainder of 307.
The next digit of our result is 7. 
Result so far: 130899.7
Subtracting 2863 from 3170 leaves us with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Moving on to step 10:
3070 divided by 409 is 7 with a remainder of 207.
Record the quotient 7 as the next digit in the result. 
Result so far: 130899.77
The remainder is 207 after subtracting 2863 from 3070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

After the division, we end up with 130899.77 and a remainder of 0.207.
