We look at the division of 638149 by 17 
We're looking to find how many times 17 goes into 638149.

On to step 1:
The number 17 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 17

Moving on to step 2:
63 divided by 17 is 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 51 from 63, we get 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 17

Let's proceed to step 3:
128 divided by 17 is 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
The remainder is 9 after subtracting 119 from 128.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 17

Going ahead to step 4:
91 divided by 17 is 5 with a remainder of 6.
The next digit of our result is 5. 
Result so far: 375.0
Subtract 85 from 91 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 17

Moving on to step 5:
17 can be fit into 64 3 times, resulting in a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 3753.0
If we subtract 51 from 64, we get 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 17

Advancing to step 6:
If we divide 139 by 17, we get 8 and a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 37538.0
If we take 136 away from 139, 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.

Step 7:
17 can be fit into 30 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 37538.1
If we subtract 17 from 30, we 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.

Going ahead to step 8:
17 can be fit into 130 7 times, resulting in a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 37538.17
The remainder is 11 after subtracting 119 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
The number 17 fits into 110 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 37538.176
The remainder is 8 after subtracting 102 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
17 can be fit into 80 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 37538.1764
Deduct 68 from 80 and we're left 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.

Advancing to step 11:
17 can be fit into 120 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 37538.17647
Subtracting 119 from 120 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
17 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 37538.17647
Subtracting 0 from 10 leaves us 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.

Going ahead to step 13:
100 divided by 17 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 37538.1764705
Deduct 85 from 100 and we're left 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.

Moving on to step 14:
17 can be fit into 150 8 times, resulting in a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 37538.17647058
Deduct 136 from 150 and we're left 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.

In conclusion, the division gives 37538.17647058 with a balance of 1.4e-08.
