We look at the division of 40663384 by 258 
We want to figure out the number of times 40663384 can be divided by 258.

On to step 1:
When dividing 4 by 258, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 258

Advancing to step 2:
When dividing 40 by 258, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Grab the next digit (6) from the dividend, add it to 40, then carry on: 406 / 258

Let's proceed to step 3:
The number 258 fits into 406 1 times, leaving a remainder of 148.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 148 after subtracting 258 from 406.
Bring next digit (6) of the dividend behind the 148 and repeat the process: 1486 / 258

Let's proceed to step 4:
258 goes into 1486 5 times with a remainder of 196.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 1290 from 1486, we get 196.
Bring next digit (3) of the dividend behind the 196 and repeat the process: 1963 / 258

On to step 5:
258 goes into 1963 7 times with a remainder of 157.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
Deduct 1806 from 1963 and we're left with 157.
Append the next digit (3) from the dividend to 157 and continue with: 1573 / 258

Advancing to step 6:
When dividing 1573 by 258, we get 6 with a remainder of 25.
Use 6 as the next digit of our solution. 
Result so far: 1576.0
If we subtract 1548 from 1573, we get 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 258

On to step 7:
The number 258 fits into 258 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 15761.0
If we take 258 away from 258, we end up with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 258

Advancing to step 8:
258 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 157610.0
If we take 0 away from 4, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
When dividing 40 by 258, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 157610.0
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
258 goes into 400 1 times with a remainder of 142.
Use 1 as the next digit of our solution. 
Result so far: 157610.01
The remainder is 142 after subtracting 258 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 11:
The number 258 fits into 1420 5 times, leaving a remainder of 130.
Record the quotient 5 as the next digit in the result. 
Result so far: 157610.015
If we subtract 1290 from 1420, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 12:
The number 258 fits into 1300 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 157610.0155
If we take 1290 away from 1300, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 157610.0155, with a leftover of 0.0001.
