We divide 52457037 by 409
We want to figure out the number of times 52457037 can be divided by 409.

On to step 1:
409 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 409

Step 2:
409 goes into 52 0 times with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Fetch the next digit (4) from the dividend, attach it to 52 and continue: 524 / 409

On to step 3:
409 goes into 524 1 times with a remainder of 115.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 115 after subtracting 409 from 524.
Include the next digit (5) from the dividend after 115, then repeat: 1155 / 409

Going ahead to step 4:
The number 409 fits into 1155 2 times, leaving a remainder of 337.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 818 from 1155 and we're left with 337.
Take the next digit (7) from the dividend and append it to 337, then repeat: 3377 / 409

Going ahead to step 5:
409 can be fit into 3377 8 times, resulting in a remainder of 105.
The next digit of our result is 8. 
Result so far: 128.0
If we subtract 3272 from 3377, we get 105.
Grab the next digit (0) from the dividend, add it to 105, then carry on: 1050 / 409

On to step 6:
1050 divided by 409 is 2 with a remainder of 232.
The number 2 becomes the next digit in our result. 
Result so far: 1282.0
Subtract 818 from 1050 to get 232.
Include the next digit (3) from the dividend after 232, then repeat: 2323 / 409

Step 7:
2323 divided by 409 is 5 with a remainder of 278.
Put 5 as the next digit of the answer. 
Result so far: 12825.0
Deduct 2045 from 2323 and we're left with 278.
Bring next digit (7) of the dividend behind the 278 and repeat the process: 2787 / 409

Step 8:
The number 409 fits into 2787 6 times, leaving a remainder of 333.
Record the quotient 6 as the next digit in the result. 
Result so far: 128256.0
If we subtract 2454 from 2787, we get 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Moving on to step 9:
The number 409 fits into 3330 8 times, leaving a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 128256.8
If we subtract 3272 from 3330, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 10:
580 divided by 409 is 1 with a remainder of 171.
Record the quotient 1 as the next digit in the result. 
Result so far: 128256.81
Subtract 409 from 580 to get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

On to step 11:
409 can be fit into 1710 4 times, resulting in a remainder of 74.
The next digit of our result is 4. 
Result so far: 128256.814
If we subtract 1636 from 1710, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 12:
When dividing 740 by 409, we get 1 with a remainder of 331.
The number 1 becomes the next digit in our result. 
Result so far: 128256.8141
The remainder is 331 after subtracting 409 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

On to step 13:
409 goes into 3310 8 times with a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 128256.81418
The remainder is 38 after subtracting 3272 from 3310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 14:
409 can be fit into 380 0 times, resulting in a remainder of 380.
Write down 0 as next digit of the result. 
Result so far: 128256.81418
Subtracting 0 from 380 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 15:
409 goes into 3800 9 times with a remainder of 119.
Record the quotient 9 as the next digit in the result. 
Result so far: 128256.8141809
If we subtract 3681 from 3800, we get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

On to step 16:
409 can be fit into 1190 2 times, resulting in a remainder of 372.
Use 2 as the next digit of our solution. 
Result so far: 128256.81418092
Deduct 818 from 1190 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

In conclusion, the division gives 128256.81418092 with a balance of 3.72e-07.
