78774052 ÷ 261 
We're looking to find how many times 261 goes into 78774052.

Let's proceed to step 1:
261 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 261

Going ahead to step 2:
When dividing 78 by 261, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Include the next digit (7) from the dividend after 78, then repeat: 787 / 261

Going ahead to step 3:
261 goes into 787 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 783 from 787 to get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 261

Going ahead to step 4:
When dividing 47 by 261, we get 0 with a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we subtract 0 from 47, we get 47.
Bring next digit (4) of the dividend behind the 47 and repeat the process: 474 / 261

On to step 5:
When dividing 474 by 261, we get 1 with a remainder of 213.
The next digit of our result is 1. 
Result so far: 301.0
Subtract 261 from 474 to get 213.
Include the next digit (0) from the dividend after 213, then repeat: 2130 / 261

Step 6:
The number 261 fits into 2130 8 times, leaving a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 3018.0
The remainder is 42 after subtracting 2088 from 2130.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 261

Moving on to step 7:
261 can be fit into 425 1 times, resulting in a remainder of 164.
Write down 1 as next digit of the result. 
Result so far: 30181.0
If we subtract 261 from 425, we get 164.
Bring next digit (2) of the dividend behind the 164 and repeat the process: 1642 / 261

Advancing to step 8:
261 can be fit into 1642 6 times, resulting in a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 301816.0
If we take 1566 away from 1642, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 9:
261 goes into 760 2 times with a remainder of 238.
The next digit of our result is 2. 
Result so far: 301816.2
If we subtract 522 from 760, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 10:
If we divide 2380 by 261, we get 9 and a remainder of 31.
The next digit of our result is 9. 
Result so far: 301816.29
If we take 2349 away from 2380, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 11:
The number 261 fits into 310 1 times, leaving a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 301816.291
If we subtract 261 from 310, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 12:
If we divide 490 by 261, we get 1 and a remainder of 229.
The number 1 becomes the next digit in our result. 
Result so far: 301816.2911
If we take 261 away from 490, we end up with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

In conclusion, the division gives 301816.2911 with a balance of 0.00229.
