We're dividing 77743240 by 258 
We want to figure out the number of times 77743240 can be divided by 258.

Advancing to step 1:
258 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 258

Let's proceed to step 2:
When dividing 77 by 258, we get 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 258

Step 3:
When dividing 777 by 258, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 774 from 777 and we're left with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 258

Let's proceed to step 4:
258 goes into 34 0 times with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we take 0 away from 34, we end up with 34.
Grab the next digit (3) from the dividend, add it to 34, then carry on: 343 / 258

Going ahead to step 5:
If we divide 343 by 258, we get 1 and a remainder of 85.
Put 1 as the next digit of the answer. 
Result so far: 301.0
If we subtract 258 from 343, we get 85.
Grab the next digit (2) from the dividend, add it to 85, then carry on: 852 / 258

Going ahead to step 6:
When dividing 852 by 258, we get 3 with a remainder of 78.
Write down 3 as next digit of the result. 
Result so far: 3013.0
Deduct 774 from 852 and we're left with 78.
Take the next digit (4) from the dividend and append it to 78, then repeat: 784 / 258

Advancing to step 7:
258 can be fit into 784 3 times, resulting in a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 30133.0
Deduct 774 from 784 and we're left with 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 258

Step 8:
When dividing 100 by 258, we get 0 with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 301330.0
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 9:
If we divide 1000 by 258, we get 3 and a remainder of 226.
Use 3 as the next digit of our solution. 
Result so far: 301330.3
If we subtract 774 from 1000, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Going ahead to step 10:
258 can be fit into 2260 8 times, resulting in a remainder of 196.
The number 8 becomes the next digit in our result. 
Result so far: 301330.38
The remainder is 196 after subtracting 2064 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 11:
When dividing 1960 by 258, we get 7 with a remainder of 154.
The number 7 becomes the next digit in our result. 
Result so far: 301330.387
Subtract 1806 from 1960 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 12:
If we divide 1540 by 258, we get 5 and a remainder of 250.
The next digit of our result is 5. 
Result so far: 301330.3875
Deduct 1290 from 1540 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 13:
258 goes into 2500 9 times with a remainder of 178.
Put 9 as the next digit of the answer. 
Result so far: 301330.38759
Subtract 2322 from 2500 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Advancing to step 14:
258 can be fit into 1780 6 times, resulting in a remainder of 232.
Use 6 as the next digit of our solution. 
Result so far: 301330.387596
Subtracting 1548 from 1780 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 15:
The number 258 fits into 2320 8 times, leaving a remainder of 256.
Record the quotient 8 as the next digit in the result. 
Result so far: 301330.3875968
Deduct 2064 from 2320 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 16:
2560 divided by 258 is 9 with a remainder of 238.
Use 9 as the next digit of our solution. 
Result so far: 301330.38759689
The remainder is 238 after subtracting 2322 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

The final result is 301330.38759689 with a remainder of 2.38e-07.
