We're dividing 859140 by 17 
We want to figure out the number of times 859140 can be divided by 17.

Let's proceed to step 1:
8 divided by 17 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 17

Let's proceed to step 2:
If we divide 85 by 17, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 85 from 85 leaves us with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 17

Advancing to step 3:
9 divided by 17 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 50.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 17

Let's proceed to step 4:
17 goes into 91 5 times with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 505.0
Subtract 85 from 91 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 17

On to step 5:
When dividing 64 by 17, we get 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 5053.0
Subtract 51 from 64 to get 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 17

Advancing to step 6:
17 goes into 130 7 times with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 50537.0
Subtract 119 from 130 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.

Moving on to step 7:
The number 17 fits into 110 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 50537.6
If we subtract 102 from 110, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
17 can be fit into 80 4 times, resulting in a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 50537.64
If we take 68 away from 80, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
17 goes into 120 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 50537.647
Subtract 119 from 120 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 10:
If we divide 10 by 17, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 50537.647
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
17 goes into 100 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 50537.64705
Subtract 85 from 100 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
17 can be fit into 150 8 times, resulting in a remainder of 14.
The next digit of our result is 8. 
Result so far: 50537.647058
If we take 136 away from 150, we end up 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.

Moving on to step 13:
140 divided by 17 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 50537.6470588
Subtract 136 from 140 to 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.

After the division, we end up with 50537.6470588 and a remainder of 4e-08.
