53440293 divided by 402 
We're looking to find how many times 402 goes into 53440293.

On to step 1:
If we divide 5 by 402, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 402

Moving on to step 2:
53 divided by 402 is 0 with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Append the next digit (4) from the dividend to 53 and continue with: 534 / 402

Step 3:
534 divided by 402 is 1 with a remainder of 132.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 402 from 534 leaves us with 132.
Fetch the next digit (4) from the dividend, attach it to 132 and continue: 1324 / 402

Moving on to step 4:
The number 402 fits into 1324 3 times, leaving a remainder of 118.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 1206 from 1324 and we're left with 118.
Bring next digit (0) of the dividend behind the 118 and repeat the process: 1180 / 402

On to step 5:
When dividing 1180 by 402, we get 2 with a remainder of 376.
Put 2 as the next digit of the answer. 
Result so far: 132.0
If we subtract 804 from 1180, we get 376.
Append the next digit (2) from the dividend to 376 and continue with: 3762 / 402

Moving on to step 6:
402 can be fit into 3762 9 times, resulting in a remainder of 144.
The next digit of our result is 9. 
Result so far: 1329.0
If we subtract 3618 from 3762, we get 144.
Fetch the next digit (9) from the dividend, attach it to 144 and continue: 1449 / 402

On to step 7:
When dividing 1449 by 402, we get 3 with a remainder of 243.
Record the quotient 3 as the next digit in the result. 
Result so far: 13293.0
The remainder is 243 after subtracting 1206 from 1449.
Include the next digit (3) from the dividend after 243, then repeat: 2433 / 402

Moving on to step 8:
2433 divided by 402 is 6 with a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 132936.0
The remainder is 21 after subtracting 2412 from 2433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 9:
When dividing 210 by 402, we get 0 with a remainder of 210.
The next digit of our result is 0. 
Result so far: 132936.0
Subtract 0 from 210 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 10:
If we divide 2100 by 402, we get 5 and a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 132936.05
If we subtract 2010 from 2100, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 11:
The number 402 fits into 900 2 times, leaving a remainder of 96.
Record the quotient 2 as the next digit in the result. 
Result so far: 132936.052
If we subtract 804 from 900, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 12:
The number 402 fits into 960 2 times, leaving a remainder of 156.
The number 2 becomes the next digit in our result. 
Result so far: 132936.0522
If we subtract 804 from 960, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

The final outcome is 132936.0522, with a leftover of 0.00156.
