Let's divide 869900 by 17
We want to divide 869900 by 17.

On to step 1:
The number 17 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 17

Going ahead to step 2:
When dividing 86 by 17, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 85 from 86, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 17

Advancing to step 3:
If we divide 19 by 17, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 51.0
Deduct 17 from 19 and we're left with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 17

Going ahead to step 4:
29 divided by 17 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 511.0
If we subtract 17 from 29, we get 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 17

Going ahead to step 5:
The number 17 fits into 120 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 5117.0
If we subtract 119 from 120, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 17

Going ahead to step 6:
10 divided by 17 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 51170.0
If we subtract 0 from 10, we get 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 7:
17 can be fit into 100 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 51170.5
Subtracting 85 from 100 leaves us 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.

On to step 8:
The number 17 fits into 150 8 times, leaving a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 51170.58
If we subtract 136 from 150, we get 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 9:
17 goes into 140 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 51170.588
If we take 136 away from 140, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 51170.588, and the remainder is 0.0004.
