We look at the division of 21634485 by 435 
Let's see how many times 435 fits into 21634485.

On to step 1:
The number 435 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 435

Advancing to step 2:
When dividing 21 by 435, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 435

Moving on to step 3:
435 goes into 216 0 times with a remainder of 216.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 216 leaves us with 216.
Bring next digit (3) of the dividend behind the 216 and repeat the process: 2163 / 435

Let's proceed to step 4:
435 goes into 2163 4 times with a remainder of 423.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 423 after subtracting 1740 from 2163.
Fetch the next digit (4) from the dividend, attach it to 423 and continue: 4234 / 435

Let's proceed to step 5:
If we divide 4234 by 435, we get 9 and a remainder of 319.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Deduct 3915 from 4234 and we're left with 319.
Append the next digit (4) from the dividend to 319 and continue with: 3194 / 435

Moving on to step 6:
If we divide 3194 by 435, we get 7 and a remainder of 149.
Record the quotient 7 as the next digit in the result. 
Result so far: 497.0
If we take 3045 away from 3194, we end up with 149.
Grab the next digit (8) from the dividend, add it to 149, then carry on: 1498 / 435

Advancing to step 7:
The number 435 fits into 1498 3 times, leaving a remainder of 193.
Record the quotient 3 as the next digit in the result. 
Result so far: 4973.0
The remainder is 193 after subtracting 1305 from 1498.
Append the next digit (5) from the dividend to 193 and continue with: 1935 / 435

Advancing to step 8:
When dividing 1935 by 435, we get 4 with a remainder of 195.
The next digit of our result is 4. 
Result so far: 49734.0
Subtract 1740 from 1935 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 9:
When dividing 1950 by 435, we get 4 with a remainder of 210.
Record the quotient 4 as the next digit in the result. 
Result so far: 49734.4
Subtract 1740 from 1950 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 10:
2100 divided by 435 is 4 with a remainder of 360.
Put 4 as the next digit of the answer. 
Result so far: 49734.44
Subtract 1740 from 2100 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Our division results in 49734.44 with a remaining 0.36.
