388947 ÷ 17 
We want to figure out the number of times 388947 can be divided by 17.

On to step 1:
When dividing 3 by 17, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 17

On to step 2:
If we divide 38 by 17, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 34 away from 38, we end up with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 17

Advancing to step 3:
17 can be fit into 48 2 times, resulting in a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtracting 34 from 48 leaves us with 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 17

Going ahead to step 4:
17 goes into 149 8 times with a remainder of 13.
The next digit of our result is 8. 
Result so far: 228.0
If we take 136 away from 149, we end up with 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 17

Advancing to step 5:
17 goes into 134 7 times with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 2287.0
If we take 119 away from 134, we end up with 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 17

Step 6:
The number 17 fits into 157 9 times, leaving a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 22879.0
Subtract 153 from 157 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.

Advancing to step 7:
17 can be fit into 40 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 22879.2
If we take 34 away from 40, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
If we divide 60 by 17, we get 3 and a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 22879.23
The remainder is 9 after subtracting 51 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
When dividing 90 by 17, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 22879.235
If we take 85 away from 90, we end up 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.

Moving on to step 10:
When dividing 50 by 17, we get 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 22879.2352
Subtract 34 from 50 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
When dividing 160 by 17, we get 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 22879.23529
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.

Going ahead to step 12:
If we divide 70 by 17, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 22879.235294
Subtracting 68 from 70 leaves us 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.

Going ahead to step 13:
When dividing 20 by 17, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 22879.2352941
Subtracting 17 from 20 leaves us 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.

Step 14:
When dividing 30 by 17, we get 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 22879.23529411
Subtract 17 from 30 to get 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 final outcome is 22879.23529411, with a leftover of 1.3e-08.
