52640592 ÷ 258 
We want to divide 52640592 by 258.

On to step 1:
The number 258 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 258

On to step 2:
258 can be fit into 52 0 times, resulting in a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Grab the next digit (6) from the dividend, add it to 52, then carry on: 526 / 258

Let's proceed to step 3:
The number 258 fits into 526 2 times, leaving a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 516 from 526 to get 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 258

On to step 4:
If we divide 104 by 258, we get 0 and a remainder of 104.
The next digit of our result is 0. 
Result so far: 20.0
The remainder is 104 after subtracting 0 from 104.
Include the next digit (0) from the dividend after 104, then repeat: 1040 / 258

Step 5:
258 goes into 1040 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 204.0
If we subtract 1032 from 1040, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 258

Going ahead to step 6:
85 divided by 258 is 0 with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 2040.0
If we take 0 away from 85, we end up with 85.
Append the next digit (9) from the dividend to 85 and continue with: 859 / 258

On to step 7:
If we divide 859 by 258, we get 3 and a remainder of 85.
Use 3 as the next digit of our solution. 
Result so far: 20403.0
Subtract 774 from 859 to get 85.
Fetch the next digit (2) from the dividend, attach it to 85 and continue: 852 / 258

Step 8:
258 can be fit into 852 3 times, resulting in a remainder of 78.
Write down 3 as next digit of the result. 
Result so far: 204033.0
Subtracting 774 from 852 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 9:
If we divide 780 by 258, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 204033.3
Deduct 774 from 780 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
If we divide 60 by 258, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 204033.3
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
If we divide 600 by 258, we get 2 and a remainder of 84.
The next digit of our result is 2. 
Result so far: 204033.302
If we take 516 away from 600, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 12:
258 can be fit into 840 3 times, resulting in a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 204033.3023
Subtract 774 from 840 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 13:
258 can be fit into 660 2 times, resulting in a remainder of 144.
Record the quotient 2 as the next digit in the result. 
Result so far: 204033.30232
Subtract 516 from 660 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 14:
The number 258 fits into 1440 5 times, leaving a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 204033.302325
Deduct 1290 from 1440 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 15:
258 can be fit into 1500 5 times, resulting in a remainder of 210.
Use 5 as the next digit of our solution. 
Result so far: 204033.3023255
Deduct 1290 from 1500 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

In conclusion, the division gives 204033.3023255 with a balance of 2.1e-06.
