We're dividing 859259 by 57 
We want to figure out the number of times 859259 can be divided by 57.

On to step 1:
If we divide 8 by 57, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 57

Advancing to step 2:
85 divided by 57 is 1 with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 57 from 85 and we're left with 28.
Bring next digit (9) of the dividend behind the 28 and repeat the process: 289 / 57

Let's proceed to step 3:
The number 57 fits into 289 5 times, leaving a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 285 from 289 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 57

Going ahead to step 4:
When dividing 42 by 57, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 150.0
The remainder is 42 after subtracting 0 from 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 57

Let's proceed to step 5:
425 divided by 57 is 7 with a remainder of 26.
The next digit of our result is 7. 
Result so far: 1507.0
If we subtract 399 from 425, we get 26.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 57

Advancing to step 6:
When dividing 269 by 57, we get 4 with a remainder of 41.
Put 4 as the next digit of the answer. 
Result so far: 15074.0
The remainder is 41 after subtracting 228 from 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
57 goes into 410 7 times with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 15074.7
Subtract 399 from 410 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 8:
57 goes into 110 1 times with a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 15074.71
The remainder is 53 after subtracting 57 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 9:
When dividing 530 by 57, we get 9 with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 15074.719
If we subtract 513 from 530, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
The number 57 fits into 170 2 times, leaving a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 15074.7192
Subtracting 114 from 170 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
When dividing 560 by 57, we get 9 with a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 15074.71929
The remainder is 47 after subtracting 513 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 12:
57 goes into 470 8 times with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 15074.719298
Subtracting 456 from 470 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
If we divide 140 by 57, we get 2 and a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 15074.7192982
Deduct 114 from 140 and we're left 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.

Going ahead to step 14:
When dividing 260 by 57, we get 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 15074.71929824
The remainder is 32 after subtracting 228 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 15074.71929824, with a leftover of 3.2e-08.
