We divide 860509 by 52
We want to figure out the number of times 860509 can be divided by 52.

Advancing to step 1:
8 divided by 52 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 52

Moving on to step 2:
When dividing 86 by 52, we get 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 52 from 86 to get 34.
Take the next digit (0) from the dividend and append it to 34, then repeat: 340 / 52

On to step 3:
340 divided by 52 is 6 with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 312 from 340 to get 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 52

Going ahead to step 4:
The number 52 fits into 285 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 165.0
Deduct 260 from 285 and we're left with 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 52

Going ahead to step 5:
250 divided by 52 is 4 with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 1654.0
If we take 208 away from 250, we end up with 42.
Append the next digit (9) from the dividend to 42 and continue with: 429 / 52

Moving on to step 6:
429 divided by 52 is 8 with a remainder of 13.
The next digit of our result is 8. 
Result so far: 16548.0
If we subtract 416 from 429, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
130 divided by 52 is 2 with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 16548.2
Subtracting 104 from 130 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
52 goes into 260 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 16548.25
If we subtract 260 from 260, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
0 divided by 52 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 16548.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
52 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16548.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 16548.25, with a leftover of 0.0.
