We look at the division of 53563335 by 258 
We're looking to find how many times 258 goes into 53563335.

Step 1:
The number 258 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 258

Going ahead to step 2:
The number 258 fits into 53 0 times, leaving a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Bring next digit (5) of the dividend behind the 53 and repeat the process: 535 / 258

Advancing to step 3:
The number 258 fits into 535 2 times, leaving a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 516 from 535 leaves us with 19.
Include the next digit (6) from the dividend after 19, then repeat: 196 / 258

On to step 4:
196 divided by 258 is 0 with a remainder of 196.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 196 to get 196.
Fetch the next digit (3) from the dividend, attach it to 196 and continue: 1963 / 258

Advancing to step 5:
The number 258 fits into 1963 7 times, leaving a remainder of 157.
Put 7 as the next digit of the answer. 
Result so far: 207.0
If we take 1806 away from 1963, we end up with 157.
Fetch the next digit (3) from the dividend, attach it to 157 and continue: 1573 / 258

Let's proceed to step 6:
258 goes into 1573 6 times with a remainder of 25.
The number 6 becomes the next digit in our result. 
Result so far: 2076.0
Subtract 1548 from 1573 to get 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 258

Let's proceed to step 7:
253 divided by 258 is 0 with a remainder of 253.
Use 0 as the next digit of our solution. 
Result so far: 20760.0
The remainder is 253 after subtracting 0 from 253.
Grab the next digit (5) from the dividend, add it to 253, then carry on: 2535 / 258

Advancing to step 8:
258 can be fit into 2535 9 times, resulting in a remainder of 213.
Record the quotient 9 as the next digit in the result. 
Result so far: 207609.0
If we subtract 2322 from 2535, we get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Let's proceed to step 9:
When dividing 2130 by 258, we get 8 with a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 207609.8
Subtracting 2064 from 2130 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
258 can be fit into 660 2 times, resulting in a remainder of 144.
Record the quotient 2 as the next digit in the result. 
Result so far: 207609.82
Deduct 516 from 660 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 11:
258 can be fit into 1440 5 times, resulting in a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 207609.825
If we take 1290 away from 1440, we end up 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.

Moving on to step 12:
258 can be fit into 1500 5 times, resulting in a remainder of 210.
Write down 5 as next digit of the result. 
Result so far: 207609.8255
Subtracting 1290 from 1500 leaves us 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.

The final outcome is 207609.8255, with a leftover of 0.0021.
