Let's divide 53993438 by 750
We want to divide 53993438 by 750.

Step 1:
If we divide 5 by 750, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 750

Step 2:
The number 750 fits into 53 0 times, leaving 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.
Include the next digit (9) from the dividend after 53, then repeat: 539 / 750

Let's proceed to step 3:
When dividing 539 by 750, we get 0 with a remainder of 539.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 539 to get 539.
Grab the next digit (9) from the dividend, add it to 539, then carry on: 5399 / 750

Step 4:
750 goes into 5399 7 times with a remainder of 149.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 5250 from 5399 leaves us with 149.
Take the next digit (3) from the dividend and append it to 149, then repeat: 1493 / 750

Advancing to step 5:
If we divide 1493 by 750, we get 1 and a remainder of 743.
The next digit of our result is 1. 
Result so far: 71.0
If we subtract 750 from 1493, we get 743.
Grab the next digit (4) from the dividend, add it to 743, then carry on: 7434 / 750

Let's proceed to step 6:
750 goes into 7434 9 times with a remainder of 684.
Write down 9 as next digit of the result. 
Result so far: 719.0
Deduct 6750 from 7434 and we're left with 684.
Fetch the next digit (3) from the dividend, attach it to 684 and continue: 6843 / 750

On to step 7:
The number 750 fits into 6843 9 times, leaving a remainder of 93.
Put 9 as the next digit of the answer. 
Result so far: 7199.0
If we take 6750 away from 6843, we end up with 93.
Append the next digit (8) from the dividend to 93 and continue with: 938 / 750

Advancing to step 8:
750 goes into 938 1 times with a remainder of 188.
The next digit of our result is 1. 
Result so far: 71991.0
If we take 750 away from 938, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 9:
If we divide 1880 by 750, we get 2 and a remainder of 380.
The number 2 becomes the next digit in our result. 
Result so far: 71991.2
If we take 1500 away from 1880, we end up 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.

On to step 10:
750 can be fit into 3800 5 times, resulting in a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 71991.25
Deduct 3750 from 3800 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
750 can be fit into 500 0 times, resulting in a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 71991.25
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 12:
750 goes into 5000 6 times with a remainder of 500.
Put 6 as the next digit of the answer. 
Result so far: 71991.2506
If we take 4500 away from 5000, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 13:
When dividing 5000 by 750, we get 6 with a remainder of 500.
Record the quotient 6 as the next digit in the result. 
Result so far: 71991.25066
If we take 4500 away from 5000, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

After the division, we end up with 71991.25066 and a remainder of 0.0005.
