We're dividing 21388853 by 757 
Let's see how many times 757 fits into 21388853.

Advancing to step 1:
If we divide 2 by 757, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 757

Let's proceed to step 2:
21 divided by 757 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 757

On to step 3:
When dividing 213 by 757, we get 0 with a remainder of 213.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 213, we get 213.
Include the next digit (8) from the dividend after 213, then repeat: 2138 / 757

Going ahead to step 4:
757 goes into 2138 2 times with a remainder of 624.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 624 after subtracting 1514 from 2138.
Append the next digit (8) from the dividend to 624 and continue with: 6248 / 757

Let's proceed to step 5:
If we divide 6248 by 757, we get 8 and a remainder of 192.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Deduct 6056 from 6248 and we're left with 192.
Bring next digit (8) of the dividend behind the 192 and repeat the process: 1928 / 757

Moving on to step 6:
If we divide 1928 by 757, we get 2 and a remainder of 414.
The number 2 becomes the next digit in our result. 
Result so far: 282.0
The remainder is 414 after subtracting 1514 from 1928.
Grab the next digit (5) from the dividend, add it to 414, then carry on: 4145 / 757

On to step 7:
The number 757 fits into 4145 5 times, leaving a remainder of 360.
Record the quotient 5 as the next digit in the result. 
Result so far: 2825.0
Deduct 3785 from 4145 and we're left with 360.
Fetch the next digit (3) from the dividend, attach it to 360 and continue: 3603 / 757

On to step 8:
3603 divided by 757 is 4 with a remainder of 575.
The number 4 becomes the next digit in our result. 
Result so far: 28254.0
If we subtract 3028 from 3603, we get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Advancing to step 9:
5750 divided by 757 is 7 with a remainder of 451.
Use 7 as the next digit of our solution. 
Result so far: 28254.7
If we subtract 5299 from 5750, we get 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Let's proceed to step 10:
757 goes into 4510 5 times with a remainder of 725.
Write down 5 as next digit of the result. 
Result so far: 28254.75
The remainder is 725 after subtracting 3785 from 4510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Going ahead to step 11:
7250 divided by 757 is 9 with a remainder of 437.
Put 9 as the next digit of the answer. 
Result so far: 28254.759
Subtracting 6813 from 7250 leaves us with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

On to step 12:
757 can be fit into 4370 5 times, resulting in a remainder of 585.
The number 5 becomes the next digit in our result. 
Result so far: 28254.7595
Subtracting 3785 from 4370 leaves us with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Moving on to step 13:
757 can be fit into 5850 7 times, resulting in a remainder of 551.
The number 7 becomes the next digit in our result. 
Result so far: 28254.75957
If we take 5299 away from 5850, 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.

Advancing to step 14:
If we divide 5510 by 757, we get 7 and a remainder of 211.
Write down 7 as next digit of the result. 
Result so far: 28254.759577
Subtract 5299 from 5510 to get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

The quotient of the division is 28254.759577, and the remainder is 2.11e-05.
