We're dividing 40575938 by 258 
We want to figure out the number of times 40575938 can be divided by 258.

Moving on to step 1:
4 divided by 258 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 258

Let's proceed to step 2:
258 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 258

Advancing to step 3:
If we divide 405 by 258, we get 1 and a remainder of 147.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 258 from 405, we get 147.
Grab the next digit (7) from the dividend, add it to 147, then carry on: 1477 / 258

Advancing to step 4:
When dividing 1477 by 258, we get 5 with a remainder of 187.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 1290 from 1477 leaves us with 187.
Grab the next digit (5) from the dividend, add it to 187, then carry on: 1875 / 258

On to step 5:
If we divide 1875 by 258, we get 7 and a remainder of 69.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
If we take 1806 away from 1875, we end up with 69.
Include the next digit (9) from the dividend after 69, then repeat: 699 / 258

Going ahead to step 6:
258 can be fit into 699 2 times, resulting in a remainder of 183.
The number 2 becomes the next digit in our result. 
Result so far: 1572.0
The remainder is 183 after subtracting 516 from 699.
Include the next digit (3) from the dividend after 183, then repeat: 1833 / 258

Let's proceed to step 7:
When dividing 1833 by 258, we get 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 15727.0
Subtracting 1806 from 1833 leaves us with 27.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 258

Moving on to step 8:
The number 258 fits into 278 1 times, leaving a remainder of 20.
The next digit of our result is 1. 
Result so far: 157271.0
Subtracting 258 from 278 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
The number 258 fits into 200 0 times, leaving a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 157271.0
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 10:
258 goes into 2000 7 times with a remainder of 194.
Write down 7 as next digit of the result. 
Result so far: 157271.07
Deduct 1806 from 2000 and we're left with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Advancing to step 11:
If we divide 1940 by 258, we get 7 and a remainder of 134.
The next digit of our result is 7. 
Result so far: 157271.077
Deduct 1806 from 1940 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

In conclusion, the division gives 157271.077 with a balance of 0.0134.
