258579 divided by 63 
We want to figure out the number of times 258579 can be divided by 63.

On to step 1:
63 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 63

Advancing to step 2:
The number 63 fits into 25 0 times, leaving a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 63

Let's proceed to step 3:
The number 63 fits into 258 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 252 away from 258, we end up with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 63

Advancing to step 4:
If we divide 65 by 63, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 41.0
The remainder is 2 after subtracting 63 from 65.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 63

Moving on to step 5:
The number 63 fits into 27 0 times, leaving a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 410.0
Subtracting 0 from 27 leaves us with 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 63

Going ahead to step 6:
279 divided by 63 is 4 with a remainder of 27.
The next digit of our result is 4. 
Result so far: 4104.0
The remainder is 27 after subtracting 252 from 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
270 divided by 63 is 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 4104.4
If we subtract 252 from 270, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
If we divide 180 by 63, we get 2 and a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 4104.42
The remainder is 54 after subtracting 126 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 9:
The number 63 fits into 540 8 times, leaving a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 4104.428
Subtract 504 from 540 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
If we divide 360 by 63, we get 5 and a remainder of 45.
The next digit of our result is 5. 
Result so far: 4104.4285
If we take 315 away from 360, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 11:
63 goes into 450 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 4104.42857
Deduct 441 from 450 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 12:
When dividing 90 by 63, we get 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 4104.428571
If we subtract 63 from 90, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 13:
If we divide 270 by 63, we get 4 and a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 4104.4285714
The remainder is 18 after subtracting 252 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 14:
When dividing 180 by 63, we get 2 with a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 4104.42857142
If we take 126 away from 180, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 4104.42857142 with a remainder of 5.4e-08.
