We divide 642724 by 17
We're looking to find how many times 17 goes into 642724.

On to step 1:
The number 17 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 17

On to step 2:
17 goes into 64 3 times with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 51 from 64 to get 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 17

Step 3:
17 can be fit into 132 7 times, resulting in a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 37.0
If we take 119 away from 132, we end up with 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 17

Step 4:
17 goes into 137 8 times with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 378.0
Deduct 136 from 137 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 17

Advancing to step 5:
When dividing 12 by 17, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 3780.0
If we take 0 away from 12, we end up with 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 17

Moving on to step 6:
124 divided by 17 is 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 37807.0
If we take 119 away from 124, 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.

Step 7:
17 can be fit into 50 2 times, resulting in a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 37807.2
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.

Step 8:
160 divided by 17 is 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 37807.29
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.

Step 9:
17 goes into 70 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 37807.294
Subtract 68 from 70 to 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.

Advancing to step 10:
17 can be fit into 20 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 37807.2941
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 11:
When dividing 30 by 17, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 37807.29411
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.

In conclusion, the division gives 37807.29411 with a balance of 1.3e-05.
