We look at the division of 53555916 by 435 
We want to divide 53555916 by 435.

On to step 1:
If we divide 5 by 435, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 435

Advancing to step 2:
When dividing 53 by 435, we get 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Take the next digit (5) from the dividend and append it to 53, then repeat: 535 / 435

Advancing to step 3:
When dividing 535 by 435, we get 1 with a remainder of 100.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 435 from 535 and we're left with 100.
Grab the next digit (5) from the dividend, add it to 100, then carry on: 1005 / 435

Step 4:
435 goes into 1005 2 times with a remainder of 135.
The next digit of our result is 2. 
Result so far: 12.0
If we take 870 away from 1005, we end up with 135.
Take the next digit (5) from the dividend and append it to 135, then repeat: 1355 / 435

On to step 5:
435 can be fit into 1355 3 times, resulting in a remainder of 50.
The next digit of our result is 3. 
Result so far: 123.0
The remainder is 50 after subtracting 1305 from 1355.
Take the next digit (9) from the dividend and append it to 50, then repeat: 509 / 435

Moving on to step 6:
509 divided by 435 is 1 with a remainder of 74.
Put 1 as the next digit of the answer. 
Result so far: 1231.0
Deduct 435 from 509 and we're left with 74.
Take the next digit (1) from the dividend and append it to 74, then repeat: 741 / 435

Going ahead to step 7:
435 goes into 741 1 times with a remainder of 306.
Record the quotient 1 as the next digit in the result. 
Result so far: 12311.0
Subtract 435 from 741 to get 306.
Include the next digit (6) from the dividend after 306, then repeat: 3066 / 435

Moving on to step 8:
435 goes into 3066 7 times with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 123117.0
If we subtract 3045 from 3066, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 9:
435 can be fit into 210 0 times, resulting in a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 123117.0
If we take 0 away from 210, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 10:
435 goes into 2100 4 times with a remainder of 360.
Record the quotient 4 as the next digit in the result. 
Result so far: 123117.04
If we take 1740 away from 2100, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 11:
When dividing 3600 by 435, we get 8 with a remainder of 120.
Use 8 as the next digit of our solution. 
Result so far: 123117.048
Subtracting 3480 from 3600 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 12:
When dividing 1200 by 435, we get 2 with a remainder of 330.
Write down 2 as next digit of the result. 
Result so far: 123117.0482
Deduct 870 from 1200 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 13:
3300 divided by 435 is 7 with a remainder of 255.
The next digit of our result is 7. 
Result so far: 123117.04827
Subtracting 3045 from 3300 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 14:
When dividing 2550 by 435, we get 5 with a remainder of 375.
The next digit of our result is 5. 
Result so far: 123117.048275
If we take 2175 away from 2550, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 15:
The number 435 fits into 3750 8 times, leaving a remainder of 270.
The number 8 becomes the next digit in our result. 
Result so far: 123117.0482758
The remainder is 270 after subtracting 3480 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 16:
The number 435 fits into 2700 6 times, leaving a remainder of 90.
Write down 6 as next digit of the result. 
Result so far: 123117.04827586
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.

The final result is 123117.04827586 with a remainder of 9e-08.
