We're dividing 77203406 by 258 
We want to figure out the number of times 77203406 can be divided by 258.

Let's proceed to step 1:
When dividing 7 by 258, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 258

Going ahead to step 2:
77 divided by 258 is 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Append the next digit (2) from the dividend to 77 and continue with: 772 / 258

Let's proceed to step 3:
If we divide 772 by 258, we get 2 and a remainder of 256.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 516 from 772, we get 256.
Grab the next digit (0) from the dividend, add it to 256, then carry on: 2560 / 258

On to step 4:
258 goes into 2560 9 times with a remainder of 238.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtract 2322 from 2560 to get 238.
Grab the next digit (3) from the dividend, add it to 238, then carry on: 2383 / 258

Let's proceed to step 5:
2383 divided by 258 is 9 with a remainder of 61.
The next digit of our result is 9. 
Result so far: 299.0
Subtract 2322 from 2383 to get 61.
Take the next digit (4) from the dividend and append it to 61, then repeat: 614 / 258

Let's proceed to step 6:
When dividing 614 by 258, we get 2 with a remainder of 98.
Record the quotient 2 as the next digit in the result. 
Result so far: 2992.0
Subtracting 516 from 614 leaves us with 98.
Fetch the next digit (0) from the dividend, attach it to 98 and continue: 980 / 258

Advancing to step 7:
The number 258 fits into 980 3 times, leaving a remainder of 206.
The number 3 becomes the next digit in our result. 
Result so far: 29923.0
If we subtract 774 from 980, we get 206.
Take the next digit (6) from the dividend and append it to 206, then repeat: 2066 / 258

Going ahead to step 8:
258 can be fit into 2066 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 299238.0
If we take 2064 away from 2066, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
258 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 299238.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
If we divide 200 by 258, we get 0 and a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 299238.0
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 299238.0, and the remainder is 0.2.
