17523709 divided by 642 
We want to figure out the number of times 17523709 can be divided by 642.

On to step 1:
642 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 642

Going ahead to step 2:
If we divide 17 by 642, we get 0 and a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 642

Going ahead to step 3:
The number 642 fits into 175 0 times, leaving a remainder of 175.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 175 leaves us with 175.
Include the next digit (2) from the dividend after 175, then repeat: 1752 / 642

Let's proceed to step 4:
642 can be fit into 1752 2 times, resulting in a remainder of 468.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1284 from 1752 and we're left with 468.
Include the next digit (3) from the dividend after 468, then repeat: 4683 / 642

Step 5:
4683 divided by 642 is 7 with a remainder of 189.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
The remainder is 189 after subtracting 4494 from 4683.
Take the next digit (7) from the dividend and append it to 189, then repeat: 1897 / 642

Step 6:
1897 divided by 642 is 2 with a remainder of 613.
Record the quotient 2 as the next digit in the result. 
Result so far: 272.0
Subtracting 1284 from 1897 leaves us with 613.
Fetch the next digit (0) from the dividend, attach it to 613 and continue: 6130 / 642

Let's proceed to step 7:
642 can be fit into 6130 9 times, resulting in a remainder of 352.
Write down 9 as next digit of the result. 
Result so far: 2729.0
Subtracting 5778 from 6130 leaves us with 352.
Take the next digit (9) from the dividend and append it to 352, then repeat: 3529 / 642

Moving on to step 8:
642 can be fit into 3529 5 times, resulting in a remainder of 319.
The number 5 becomes the next digit in our result. 
Result so far: 27295.0
Deduct 3210 from 3529 and we're left with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Advancing to step 9:
If we divide 3190 by 642, we get 4 and a remainder of 622.
Use 4 as the next digit of our solution. 
Result so far: 27295.4
If we subtract 2568 from 3190, we get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Advancing to step 10:
6220 divided by 642 is 9 with a remainder of 442.
The number 9 becomes the next digit in our result. 
Result so far: 27295.49
Deduct 5778 from 6220 and we're left with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

On to step 11:
4420 divided by 642 is 6 with a remainder of 568.
Put 6 as the next digit of the answer. 
Result so far: 27295.496
If we take 3852 away from 4420, we end up with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Step 12:
When dividing 5680 by 642, we get 8 with a remainder of 544.
Use 8 as the next digit of our solution. 
Result so far: 27295.4968
Subtracting 5136 from 5680 leaves us with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Advancing to step 13:
The number 642 fits into 5440 8 times, leaving a remainder of 304.
Write down 8 as next digit of the result. 
Result so far: 27295.49688
The remainder is 304 after subtracting 5136 from 5440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

In conclusion, the division gives 27295.49688 with a balance of 0.000304.
