We look at the division of 19262915 by 642 
Our goal is to divide 19262915 by 642.

Advancing to step 1:
If we divide 1 by 642, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 642

Moving on to step 2:
When dividing 19 by 642, we get 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 642

Step 3:
642 goes into 192 0 times with a remainder of 192.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 192 and we're left with 192.
Bring next digit (6) of the dividend behind the 192 and repeat the process: 1926 / 642

Advancing to step 4:
When dividing 1926 by 642, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 1926 from 1926 leaves us with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 642

Step 5:
When dividing 2 by 642, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 642

Advancing to step 6:
When dividing 29 by 642, we get 0 with a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 300.0
If we subtract 0 from 29, we get 29.
Take the next digit (1) from the dividend and append it to 29, then repeat: 291 / 642

Step 7:
291 divided by 642 is 0 with a remainder of 291.
The number 0 becomes the next digit in our result. 
Result so far: 3000.0
The remainder is 291 after subtracting 0 from 291.
Grab the next digit (5) from the dividend, add it to 291, then carry on: 2915 / 642

Advancing to step 8:
642 can be fit into 2915 4 times, resulting in a remainder of 347.
The next digit of our result is 4. 
Result so far: 30004.0
Deduct 2568 from 2915 and we're left with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

On to step 9:
3470 divided by 642 is 5 with a remainder of 260.
The next digit of our result is 5. 
Result so far: 30004.5
Deduct 3210 from 3470 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 10:
If we divide 2600 by 642, we get 4 and a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 30004.54
Subtracting 2568 from 2600 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
When dividing 320 by 642, we get 0 with a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 30004.54
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 12:
When dividing 3200 by 642, we get 4 with a remainder of 632.
Record the quotient 4 as the next digit in the result. 
Result so far: 30004.5404
If we subtract 2568 from 3200, we get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

On to step 13:
6320 divided by 642 is 9 with a remainder of 542.
Use 9 as the next digit of our solution. 
Result so far: 30004.54049
If we subtract 5778 from 6320, we get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Advancing to step 14:
The number 642 fits into 5420 8 times, leaving a remainder of 284.
Write down 8 as next digit of the result. 
Result so far: 30004.540498
Deduct 5136 from 5420 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Going ahead to step 15:
When dividing 2840 by 642, we get 4 with a remainder of 272.
Record the quotient 4 as the next digit in the result. 
Result so far: 30004.5404984
Subtracting 2568 from 2840 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 16:
2720 divided by 642 is 4 with a remainder of 152.
The next digit of our result is 4. 
Result so far: 30004.54049844
Subtracting 2568 from 2720 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

After the division, we end up with 30004.54049844 and a remainder of 1.52e-07.
