We divide 21525961 by 574
We want to divide 21525961 by 574.

Advancing to step 1:
The number 574 fits into 2 0 times, leaving 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.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 574

On to step 2:
574 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 574

Moving on to step 3:
The number 574 fits into 215 0 times, leaving a remainder of 215.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 215, we get 215.
Bring next digit (2) of the dividend behind the 215 and repeat the process: 2152 / 574

Step 4:
The number 574 fits into 2152 3 times, leaving a remainder of 430.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 1722 from 2152, we get 430.
Include the next digit (5) from the dividend after 430, then repeat: 4305 / 574

On to step 5:
574 goes into 4305 7 times with a remainder of 287.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we subtract 4018 from 4305, we get 287.
Include the next digit (9) from the dividend after 287, then repeat: 2879 / 574

Moving on to step 6:
If we divide 2879 by 574, we get 5 and a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 375.0
Deduct 2870 from 2879 and we're left with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 574

Let's proceed to step 7:
The number 574 fits into 96 0 times, leaving a remainder of 96.
Write down 0 as next digit of the result. 
Result so far: 3750.0
Subtract 0 from 96 to get 96.
Grab the next digit (1) from the dividend, add it to 96, then carry on: 961 / 574

On to step 8:
When dividing 961 by 574, we get 1 with a remainder of 387.
Record the quotient 1 as the next digit in the result. 
Result so far: 37501.0
Subtracting 574 from 961 leaves us with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

On to step 9:
The number 574 fits into 3870 6 times, leaving a remainder of 426.
Use 6 as the next digit of our solution. 
Result so far: 37501.6
Subtract 3444 from 3870 to get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Let's proceed to step 10:
If we divide 4260 by 574, we get 7 and a remainder of 242.
The number 7 becomes the next digit in our result. 
Result so far: 37501.67
The remainder is 242 after subtracting 4018 from 4260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 11:
574 goes into 2420 4 times with a remainder of 124.
The number 4 becomes the next digit in our result. 
Result so far: 37501.674
Subtract 2296 from 2420 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 12:
When dividing 1240 by 574, we get 2 with a remainder of 92.
Record the quotient 2 as the next digit in the result. 
Result so far: 37501.6742
The remainder is 92 after subtracting 1148 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 13:
When dividing 920 by 574, we get 1 with a remainder of 346.
Record the quotient 1 as the next digit in the result. 
Result so far: 37501.67421
Subtract 574 from 920 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Going ahead to step 14:
The number 574 fits into 3460 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 37501.674216
The remainder is 16 after subtracting 3444 from 3460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 15:
160 divided by 574 is 0 with a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 37501.674216
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 16:
574 can be fit into 1600 2 times, resulting in a remainder of 452.
Put 2 as the next digit of the answer. 
Result so far: 37501.67421602
If we take 1148 away from 1600, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

The final result is 37501.67421602 with a remainder of 4.52e-07.
