Let's divide 87561583 by 258
We want to figure out the number of times 87561583 can be divided by 258.

On to step 1:
258 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 258

Step 2:
258 goes into 87 0 times with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Append the next digit (5) from the dividend to 87 and continue with: 875 / 258

Step 3:
The number 258 fits into 875 3 times, leaving a remainder of 101.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 774 from 875, we get 101.
Take the next digit (6) from the dividend and append it to 101, then repeat: 1016 / 258

Let's proceed to step 4:
If we divide 1016 by 258, we get 3 and a remainder of 242.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
If we take 774 away from 1016, we end up with 242.
Append the next digit (1) from the dividend to 242 and continue with: 2421 / 258

Let's proceed to step 5:
If we divide 2421 by 258, we get 9 and a remainder of 99.
The next digit of our result is 9. 
Result so far: 339.0
Subtracting 2322 from 2421 leaves us with 99.
Take the next digit (5) from the dividend and append it to 99, then repeat: 995 / 258

Moving on to step 6:
258 can be fit into 995 3 times, resulting in a remainder of 221.
Use 3 as the next digit of our solution. 
Result so far: 3393.0
If we take 774 away from 995, we end up with 221.
Append the next digit (8) from the dividend to 221 and continue with: 2218 / 258

Let's proceed to step 7:
When dividing 2218 by 258, we get 8 with a remainder of 154.
The number 8 becomes the next digit in our result. 
Result so far: 33938.0
If we subtract 2064 from 2218, we get 154.
Grab the next digit (3) from the dividend, add it to 154, then carry on: 1543 / 258

On to step 8:
When dividing 1543 by 258, we get 5 with a remainder of 253.
The next digit of our result is 5. 
Result so far: 339385.0
Deduct 1290 from 1543 and we're left with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Advancing to step 9:
258 goes into 2530 9 times with a remainder of 208.
The next digit of our result is 9. 
Result so far: 339385.9
If we subtract 2322 from 2530, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 10:
258 can be fit into 2080 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 339385.98
Deduct 2064 from 2080 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
258 can be fit into 160 0 times, resulting in a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 339385.98
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 12:
258 goes into 1600 6 times with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 339385.9806
Subtracting 1548 from 1600 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 13:
520 divided by 258 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 339385.98062
If we subtract 516 from 520, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
If we divide 40 by 258, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 339385.98062
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 15:
The number 258 fits into 400 1 times, leaving a remainder of 142.
Put 1 as the next digit of the answer. 
Result so far: 339385.9806201
If we take 258 away from 400, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 16:
When dividing 1420 by 258, we get 5 with a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 339385.98062015
Deduct 1290 from 1420 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

After the division, we end up with 339385.98062015 and a remainder of 1.3e-07.
