We're dividing 21735732 by 515 
Our goal is to divide 21735732 by 515.

Step 1:
If we divide 2 by 515, 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.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 515

Advancing to step 2:
If we divide 21 by 515, we get 0 and 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.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 515

Advancing to step 3:
If we divide 217 by 515, we get 0 and 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.
Fetch the next digit (3) from the dividend, attach it to 217 and continue: 2173 / 515

Advancing to step 4:
515 goes into 2173 4 times with a remainder of 113.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 2060 from 2173 to get 113.
Take the next digit (5) from the dividend and append it to 113, then repeat: 1135 / 515

Going ahead to step 5:
The number 515 fits into 1135 2 times, leaving a remainder of 105.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtracting 1030 from 1135 leaves us with 105.
Bring next digit (7) of the dividend behind the 105 and repeat the process: 1057 / 515

Going ahead to step 6:
When dividing 1057 by 515, we get 2 with a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 422.0
The remainder is 27 after subtracting 1030 from 1057.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 515

Advancing to step 7:
If we divide 273 by 515, we get 0 and a remainder of 273.
Put 0 as the next digit of the answer. 
Result so far: 4220.0
If we subtract 0 from 273, we get 273.
Fetch the next digit (2) from the dividend, attach it to 273 and continue: 2732 / 515

Step 8:
515 can be fit into 2732 5 times, resulting in a remainder of 157.
Record the quotient 5 as the next digit in the result. 
Result so far: 42205.0
Subtract 2575 from 2732 to get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Advancing to step 9:
The number 515 fits into 1570 3 times, leaving a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 42205.3
Deduct 1545 from 1570 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
When dividing 250 by 515, we get 0 with a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 42205.3
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 11:
If we divide 2500 by 515, we get 4 and a remainder of 440.
Write down 4 as next digit of the result. 
Result so far: 42205.304
Deduct 2060 from 2500 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 12:
When dividing 4400 by 515, we get 8 with a remainder of 280.
Use 8 as the next digit of our solution. 
Result so far: 42205.3048
The remainder is 280 after subtracting 4120 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 13:
If we divide 2800 by 515, we get 5 and a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 42205.30485
The remainder is 225 after subtracting 2575 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 14:
515 can be fit into 2250 4 times, resulting in a remainder of 190.
Write down 4 as next digit of the result. 
Result so far: 42205.304854
If we subtract 2060 from 2250, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 15:
If we divide 1900 by 515, we get 3 and a remainder of 355.
Record the quotient 3 as the next digit in the result. 
Result so far: 42205.3048543
The remainder is 355 after subtracting 1545 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Let's proceed to step 16:
If we divide 3550 by 515, we get 6 and a remainder of 460.
Record the quotient 6 as the next digit in the result. 
Result so far: 42205.30485436
If we take 3090 away from 3550, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

The final result is 42205.30485436 with a remainder of 4.6e-07.
