We're dividing 21573558 by 435 
Let's see how many times 435 fits into 21573558.

Let's proceed to step 1:
435 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 435

Let's proceed to step 2:
435 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 435

Step 3:
When dividing 215 by 435, we get 0 with a remainder of 215.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 215 to get 215.
Bring next digit (7) of the dividend behind the 215 and repeat the process: 2157 / 435

Going ahead to step 4:
When dividing 2157 by 435, we get 4 with a remainder of 417.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 1740 away from 2157, we end up with 417.
Append the next digit (3) from the dividend to 417 and continue with: 4173 / 435

Advancing to step 5:
435 can be fit into 4173 9 times, resulting in a remainder of 258.
Put 9 as the next digit of the answer. 
Result so far: 49.0
If we subtract 3915 from 4173, we get 258.
Fetch the next digit (5) from the dividend, attach it to 258 and continue: 2585 / 435

Advancing to step 6:
2585 divided by 435 is 5 with a remainder of 410.
Use 5 as the next digit of our solution. 
Result so far: 495.0
Deduct 2175 from 2585 and we're left with 410.
Bring next digit (5) of the dividend behind the 410 and repeat the process: 4105 / 435

Going ahead to step 7:
When dividing 4105 by 435, we get 9 with a remainder of 190.
Use 9 as the next digit of our solution. 
Result so far: 4959.0
Deduct 3915 from 4105 and we're left with 190.
Fetch the next digit (8) from the dividend, attach it to 190 and continue: 1908 / 435

Moving on to step 8:
The number 435 fits into 1908 4 times, leaving a remainder of 168.
Use 4 as the next digit of our solution. 
Result so far: 49594.0
Subtracting 1740 from 1908 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 9:
If we divide 1680 by 435, we get 3 and a remainder of 375.
The number 3 becomes the next digit in our result. 
Result so far: 49594.3
If we subtract 1305 from 1680, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

On to step 10:
The number 435 fits into 3750 8 times, leaving a remainder of 270.
Record the quotient 8 as the next digit in the result. 
Result so far: 49594.38
Subtract 3480 from 3750 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 11:
2700 divided by 435 is 6 with a remainder of 90.
The next digit of our result is 6. 
Result so far: 49594.386
Deduct 2610 from 2700 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 12:
435 goes into 900 2 times with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 49594.3862
Deduct 870 from 900 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
If we divide 300 by 435, we get 0 and a remainder of 300.
The next digit of our result is 0. 
Result so far: 49594.3862
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 14:
435 can be fit into 3000 6 times, resulting in a remainder of 390.
The next digit of our result is 6. 
Result so far: 49594.386206
If we take 2610 away from 3000, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 15:
3900 divided by 435 is 8 with a remainder of 420.
The number 8 becomes the next digit in our result. 
Result so far: 49594.3862068
If we subtract 3480 from 3900, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 16:
435 goes into 4200 9 times with a remainder of 285.
Put 9 as the next digit of the answer. 
Result so far: 49594.38620689
Subtracting 3915 from 4200 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Our division results in 49594.38620689 with a remaining 2.85e-07.
