Let's divide 21375423 by 525
Our goal is to divide 21375423 by 525.

Moving on to step 1:
If we divide 2 by 525, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
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 / 525

On to step 2:
If we divide 21 by 525, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 525

Let's proceed to step 3:
213 divided by 525 is 0 with a remainder of 213.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 213 after subtracting 0 from 213.
Fetch the next digit (7) from the dividend, attach it to 213 and continue: 2137 / 525

Step 4:
When dividing 2137 by 525, we get 4 with a remainder of 37.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 2100 away from 2137, we end up with 37.
Fetch the next digit (5) from the dividend, attach it to 37 and continue: 375 / 525

Advancing to step 5:
The number 525 fits into 375 0 times, leaving a remainder of 375.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we take 0 away from 375, we end up with 375.
Fetch the next digit (4) from the dividend, attach it to 375 and continue: 3754 / 525

Let's proceed to step 6:
The number 525 fits into 3754 7 times, leaving a remainder of 79.
Write down 7 as next digit of the result. 
Result so far: 407.0
Subtracting 3675 from 3754 leaves us with 79.
Grab the next digit (2) from the dividend, add it to 79, then carry on: 792 / 525

Moving on to step 7:
525 can be fit into 792 1 times, resulting in a remainder of 267.
The next digit of our result is 1. 
Result so far: 4071.0
Subtracting 525 from 792 leaves us with 267.
Take the next digit (3) from the dividend and append it to 267, then repeat: 2673 / 525

Advancing to step 8:
When dividing 2673 by 525, we get 5 with a remainder of 48.
Write down 5 as next digit of the result. 
Result so far: 40715.0
If we take 2625 away from 2673, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
525 goes into 480 0 times with a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 40715.0
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 10:
When dividing 4800 by 525, we get 9 with a remainder of 75.
Record the quotient 9 as the next digit in the result. 
Result so far: 40715.09
Subtracting 4725 from 4800 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 11:
750 divided by 525 is 1 with a remainder of 225.
The next digit of our result is 1. 
Result so far: 40715.091
Deduct 525 from 750 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 12:
525 goes into 2250 4 times with a remainder of 150.
Record the quotient 4 as the next digit in the result. 
Result so far: 40715.0914
Deduct 2100 from 2250 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 13:
The number 525 fits into 1500 2 times, leaving a remainder of 450.
The next digit of our result is 2. 
Result so far: 40715.09142
Deduct 1050 from 1500 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 14:
If we divide 4500 by 525, we get 8 and a remainder of 300.
Write down 8 as next digit of the result. 
Result so far: 40715.091428
Subtract 4200 from 4500 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 15:
525 can be fit into 3000 5 times, resulting in a remainder of 375.
Record the quotient 5 as the next digit in the result. 
Result so far: 40715.0914285
The remainder is 375 after subtracting 2625 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Going ahead to step 16:
3750 divided by 525 is 7 with a remainder of 75.
Write down 7 as next digit of the result. 
Result so far: 40715.09142857
The remainder is 75 after subtracting 3675 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Our division results in 40715.09142857 with a remaining 7.5e-08.
