We look at the division of 215710 by 17 
We want to figure out the number of times 215710 can be divided by 17.

Let's proceed to step 1:
2 divided by 17 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 17

Advancing to step 2:
21 divided by 17 is 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 17 from 21 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 17

Going ahead to step 3:
The number 17 fits into 45 2 times, leaving a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 34 from 45 to get 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 17

Let's proceed to step 4:
When dividing 117 by 17, we get 6 with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 126.0
Subtract 102 from 117 to get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 17

Let's proceed to step 5:
151 divided by 17 is 8 with a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 1268.0
If we take 136 away from 151, we end up with 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 17

Advancing to step 6:
When dividing 150 by 17, we get 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 12688.0
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.

Step 7:
If we divide 140 by 17, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 12688.8
The remainder is 4 after subtracting 136 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
17 goes into 40 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 12688.82
If we subtract 34 from 40, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
17 goes into 60 3 times with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 12688.823
Subtract 51 from 60 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
17 goes into 90 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 12688.8235
The remainder is 5 after subtracting 85 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 11:
The number 17 fits into 50 2 times, leaving a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 12688.82352
The remainder is 16 after subtracting 34 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
160 divided by 17 is 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 12688.823529
Deduct 153 from 160 and we're left 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.

On to step 13:
When dividing 70 by 17, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 12688.8235294
If we subtract 68 from 70, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
If we divide 20 by 17, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 12688.82352941
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.

The quotient of the division is 12688.82352941, and the remainder is 3e-09.
