We look at the division of 21313946 by 753 
Our goal is to divide 21313946 by 753.

Step 1:
753 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 753

Let's proceed to step 2:
When dividing 21 by 753, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 753

Let's proceed to step 3:
When dividing 213 by 753, we get 0 with a remainder of 213.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 213, we get 213.
Fetch the next digit (1) from the dividend, attach it to 213 and continue: 2131 / 753

Advancing to step 4:
753 goes into 2131 2 times with a remainder of 625.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1506 from 2131 to get 625.
Grab the next digit (3) from the dividend, add it to 625, then carry on: 6253 / 753

Advancing to step 5:
753 goes into 6253 8 times with a remainder of 229.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
If we take 6024 away from 6253, we end up with 229.
Grab the next digit (9) from the dividend, add it to 229, then carry on: 2299 / 753

Advancing to step 6:
The number 753 fits into 2299 3 times, leaving a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 283.0
Subtract 2259 from 2299 to get 40.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 753

Going ahead to step 7:
If we divide 404 by 753, we get 0 and a remainder of 404.
Write down 0 as next digit of the result. 
Result so far: 2830.0
If we subtract 0 from 404, we get 404.
Bring next digit (6) of the dividend behind the 404 and repeat the process: 4046 / 753

Advancing to step 8:
4046 divided by 753 is 5 with a remainder of 281.
The next digit of our result is 5. 
Result so far: 28305.0
Deduct 3765 from 4046 and we're left with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

On to step 9:
2810 divided by 753 is 3 with a remainder of 551.
The next digit of our result is 3. 
Result so far: 28305.3
If we take 2259 away from 2810, we end up with 551.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Moving on to step 10:
5510 divided by 753 is 7 with a remainder of 239.
Write down 7 as next digit of the result. 
Result so far: 28305.37
Subtracting 5271 from 5510 leaves us with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Step 11:
753 goes into 2390 3 times with a remainder of 131.
Put 3 as the next digit of the answer. 
Result so far: 28305.373
Subtracting 2259 from 2390 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

On to step 12:
The number 753 fits into 1310 1 times, leaving a remainder of 557.
The next digit of our result is 1. 
Result so far: 28305.3731
Deduct 753 from 1310 and we're left with 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Step 13:
When dividing 5570 by 753, we get 7 with a remainder of 299.
Write down 7 as next digit of the result. 
Result so far: 28305.37317
Deduct 5271 from 5570 and we're left with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Moving on to step 14:
The number 753 fits into 2990 3 times, leaving a remainder of 731.
Put 3 as the next digit of the answer. 
Result so far: 28305.373173
Subtract 2259 from 2990 to get 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

Moving on to step 15:
If we divide 7310 by 753, we get 9 and a remainder of 533.
Put 9 as the next digit of the answer. 
Result so far: 28305.3731739
If we subtract 6777 from 7310, we get 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Moving on to step 16:
The number 753 fits into 5330 7 times, leaving a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 28305.37317397
Subtracting 5271 from 5330 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.
