15121476 divided by 255 
We want to figure out the number of times 15121476 can be divided by 255.

Let's proceed to step 1:
If we divide 1 by 255, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 255

Let's proceed to step 2:
When dividing 15 by 255, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 255

Advancing to step 3:
If we divide 151 by 255, we get 0 and a remainder of 151.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 151 and we're left with 151.
Take the next digit (2) from the dividend and append it to 151, then repeat: 1512 / 255

Moving on to step 4:
When dividing 1512 by 255, we get 5 with a remainder of 237.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 1275 away from 1512, we end up with 237.
Grab the next digit (1) from the dividend, add it to 237, then carry on: 2371 / 255

Moving on to step 5:
If we divide 2371 by 255, we get 9 and a remainder of 76.
Use 9 as the next digit of our solution. 
Result so far: 59.0
The remainder is 76 after subtracting 2295 from 2371.
Include the next digit (4) from the dividend after 76, then repeat: 764 / 255

Let's proceed to step 6:
764 divided by 255 is 2 with a remainder of 254.
Write down 2 as next digit of the result. 
Result so far: 592.0
The remainder is 254 after subtracting 510 from 764.
Include the next digit (7) from the dividend after 254, then repeat: 2547 / 255

Moving on to step 7:
The number 255 fits into 2547 9 times, leaving a remainder of 252.
Record the quotient 9 as the next digit in the result. 
Result so far: 5929.0
Subtracting 2295 from 2547 leaves us with 252.
Include the next digit (6) from the dividend after 252, then repeat: 2526 / 255

Advancing to step 8:
When dividing 2526 by 255, we get 9 with a remainder of 231.
Record the quotient 9 as the next digit in the result. 
Result so far: 59299.0
If we take 2295 away from 2526, we end up with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Advancing to step 9:
2310 divided by 255 is 9 with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 59299.9
If we take 2295 away from 2310, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
When dividing 150 by 255, we get 0 with a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 59299.9
If we take 0 away from 150, we end up 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.

Advancing to step 11:
255 goes into 1500 5 times with a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 59299.905
The remainder is 225 after subtracting 1275 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Let's proceed to step 12:
When dividing 2250 by 255, we get 8 with a remainder of 210.
Put 8 as the next digit of the answer. 
Result so far: 59299.9058
If we subtract 2040 from 2250, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 13:
When dividing 2100 by 255, we get 8 with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 59299.90588
The remainder is 60 after subtracting 2040 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 59299.90588, with a leftover of 6e-05.
