753 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 753

On to step 2:
753 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 753

Advancing to step 3:
The number 753 fits into 217 0 times, leaving a remainder of 217.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 217 and we're left with 217.

Moving on to step 4:
753 can be fit into 2172 2 times, resulting in a remainder of 666.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1506 from 2172 and we're left with 666.
Bring next digit (8) of the dividend behind the 666 and repeat the process: 6668 / 753

Advancing to step 5:
The number 753 fits into 6668 8 times, leaving a remainder of 644.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
If we take 6024 away from 6668, we end up with 644.
Grab the next digit (4) from the dividend, add it to 644, then carry on: 6444 / 753

On to step 6:
6444 divided by 753 is 8 with a remainder of 420.
Record the quotient 8 as the next digit in the result. 
Result so far: 288.0
The remainder is 420 after subtracting 6024 from 6444.
Append the next digit (5) from the dividend to 420 and continue with: 4205 / 753

Moving on to step 7:
When dividing 4205 by 753, we get 5 with a remainder of 440.
Write down 5 as next digit of the result. 
Result so far: 2885.0
If we take 3765 away from 4205, we end up with 440.
Take the next digit (6) from the dividend and append it to 440, then repeat: 4406 / 753

Let's proceed to step 8:
4406 divided by 753 is 5 with a remainder of 641.
Write down 5 as next digit of the result. 
Result so far: 28855.0
Subtract 3765 from 4406 to get 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

Let's proceed to step 9:
753 goes into 6410 8 times with a remainder of 386.
Use 8 as the next digit of our solution. 
Result so far: 28855.8
Subtract 6024 from 6410 to get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Advancing to step 10:
3860 divided by 753 is 5 with a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 28855.85
Subtracting 3765 from 3860 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 11:
When dividing 950 by 753, we get 1 with a remainder of 197.
The next digit of our result is 1. 
Result so far: 28855.851
If we take 753 away from 950, we end up with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Going ahead to step 12:
When dividing 1970 by 753, we get 2 with a remainder of 464.
Record the quotient 2 as the next digit in the result. 
Result so far: 28855.8512
The remainder is 464 after subtracting 1506 from 1970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Moving on to step 13:
If we divide 4640 by 753, we get 6 and a remainder of 122.
The number 6 becomes the next digit in our result. 
Result so far: 28855.85126
Subtract 4518 from 4640 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 14:
753 can be fit into 1220 1 times, resulting in a remainder of 467.
Write down 1 as next digit of the result. 
Result so far: 28855.851261
Deduct 753 from 1220 and we're left with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

On to step 15:
753 can be fit into 4670 6 times, resulting in a remainder of 152.
Record the quotient 6 as the next digit in the result. 
Result so far: 28855.8512616
Subtracting 4518 from 4670 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 16:
753 can be fit into 1520 2 times, resulting in a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 28855.85126162
Subtract 1506 from 1520 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 28855.85126162, with a leftover of 1.4e-08.
