53403137 ÷ 240 
We want to figure out the number of times 53403137 can be divided by 240.

Going ahead to step 1:
5 divided by 240 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 240

Moving on to step 2:
53 divided by 240 is 0 with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Fetch the next digit (4) from the dividend, attach it to 53 and continue: 534 / 240

Advancing to step 3:
If we divide 534 by 240, we get 2 and a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 480 from 534, we get 54.
Fetch the next digit (0) from the dividend, attach it to 54 and continue: 540 / 240

On to step 4:
240 goes into 540 2 times with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 22.0
The remainder is 60 after subtracting 480 from 540.
Take the next digit (3) from the dividend and append it to 60, then repeat: 603 / 240

On to step 5:
240 goes into 603 2 times with a remainder of 123.
The number 2 becomes the next digit in our result. 
Result so far: 222.0
If we take 480 away from 603, we end up with 123.
Bring next digit (1) of the dividend behind the 123 and repeat the process: 1231 / 240

Moving on to step 6:
The number 240 fits into 1231 5 times, leaving a remainder of 31.
Write down 5 as next digit of the result. 
Result so far: 2225.0
Subtracting 1200 from 1231 leaves us with 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 240

Advancing to step 7:
When dividing 313 by 240, we get 1 with a remainder of 73.
The next digit of our result is 1. 
Result so far: 22251.0
The remainder is 73 after subtracting 240 from 313.
Grab the next digit (7) from the dividend, add it to 73, then carry on: 737 / 240

Going ahead to step 8:
240 can be fit into 737 3 times, resulting in a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 222513.0
Subtracting 720 from 737 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
When dividing 170 by 240, we get 0 with a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 222513.0
Subtracting 0 from 170 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 10:
If we divide 1700 by 240, we get 7 and a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 222513.07
Deduct 1680 from 1700 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
240 can be fit into 200 0 times, resulting in a remainder of 200.
The next digit of our result is 0. 
Result so far: 222513.07
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 12:
240 goes into 2000 8 times with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 222513.0708
If we take 1920 away from 2000, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
If we divide 800 by 240, we get 3 and a remainder of 80.
Write down 3 as next digit of the result. 
Result so far: 222513.07083
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 14:
800 divided by 240 is 3 with a remainder of 80.
Record the quotient 3 as the next digit in the result. 
Result so far: 222513.070833
Deduct 720 from 800 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 222513.070833 and a remainder of 8e-06.
