Let's divide 10535603 by 258
Let's see how many times 258 fits into 10535603.

Advancing to step 1:
258 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 258

Going ahead to step 2:
258 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 258

Let's proceed to step 3:
105 divided by 258 is 0 with a remainder of 105.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 105, we get 105.
Fetch the next digit (3) from the dividend, attach it to 105 and continue: 1053 / 258

Let's proceed to step 4:
258 goes into 1053 4 times with a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 1032 from 1053 to get 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 258

Step 5:
If we divide 215 by 258, we get 0 and a remainder of 215.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we subtract 0 from 215, we get 215.
Append the next digit (6) from the dividend to 215 and continue with: 2156 / 258

Let's proceed to step 6:
If we divide 2156 by 258, we get 8 and a remainder of 92.
Use 8 as the next digit of our solution. 
Result so far: 408.0
If we take 2064 away from 2156, we end up with 92.
Take the next digit (0) from the dividend and append it to 92, then repeat: 920 / 258

Moving on to step 7:
258 goes into 920 3 times with a remainder of 146.
Record the quotient 3 as the next digit in the result. 
Result so far: 4083.0
If we take 774 away from 920, we end up with 146.
Append the next digit (3) from the dividend to 146 and continue with: 1463 / 258

On to step 8:
The number 258 fits into 1463 5 times, leaving a remainder of 173.
Put 5 as the next digit of the answer. 
Result so far: 40835.0
Subtract 1290 from 1463 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Let's proceed to step 9:
258 can be fit into 1730 6 times, resulting in a remainder of 182.
Use 6 as the next digit of our solution. 
Result so far: 40835.6
The remainder is 182 after subtracting 1548 from 1730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 10:
The number 258 fits into 1820 7 times, leaving a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 40835.67
If we subtract 1806 from 1820, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
140 divided by 258 is 0 with a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 40835.67
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 12:
When dividing 1400 by 258, we get 5 with a remainder of 110.
The number 5 becomes the next digit in our result. 
Result so far: 40835.6705
Subtracting 1290 from 1400 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 13:
258 can be fit into 1100 4 times, resulting in a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 40835.67054
If we take 1032 away from 1100, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 14:
When dividing 680 by 258, we get 2 with a remainder of 164.
Put 2 as the next digit of the answer. 
Result so far: 40835.670542
The remainder is 164 after subtracting 516 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 15:
If we divide 1640 by 258, we get 6 and a remainder of 92.
The next digit of our result is 6. 
Result so far: 40835.6705426
Subtract 1548 from 1640 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 16:
258 goes into 920 3 times with a remainder of 146.
Use 3 as the next digit of our solution. 
Result so far: 40835.67054263
Subtract 774 from 920 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

After the division, we end up with 40835.67054263 and a remainder of 1.46e-07.
