We look at the division of 21850 by 17 
We want to figure out the number of times 21850 can be divided by 17.

Advancing to step 1:
If we divide 2 by 17, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 17

Moving on to step 2:
17 can be fit into 21 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 4 after subtracting 17 from 21.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 17

Let's proceed to step 3:
17 goes into 48 2 times with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 34 from 48 to get 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 17

Step 4:
17 goes into 145 8 times with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 128.0
Deduct 136 from 145 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 17

Advancing to step 5:
17 goes into 90 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1285.0
Subtracting 85 from 90 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 6:
17 can be fit into 50 2 times, resulting in a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 1285.2
Subtracting 34 from 50 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
If we divide 160 by 17, we get 9 and a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 1285.29
If we take 153 away from 160, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
When dividing 70 by 17, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 1285.294
Deduct 68 from 70 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
17 goes into 20 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1285.2941
If we take 17 away from 20, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
If we divide 30 by 17, we get 1 and a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1285.29411
Deduct 17 from 30 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The quotient of the division is 1285.29411, and the remainder is 1.3e-05.
