We divide 18912304 by 642
We want to divide 18912304 by 642.

Advancing to step 1:
The number 642 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 642

Step 2:
If we divide 18 by 642, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 642

Advancing to step 3:
642 can be fit into 189 0 times, resulting in a remainder of 189.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 189 and we're left with 189.
Bring next digit (1) of the dividend behind the 189 and repeat the process: 1891 / 642

Going ahead to step 4:
The number 642 fits into 1891 2 times, leaving a remainder of 607.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 607 after subtracting 1284 from 1891.
Take the next digit (2) from the dividend and append it to 607, then repeat: 6072 / 642

Let's proceed to step 5:
The number 642 fits into 6072 9 times, leaving a remainder of 294.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we subtract 5778 from 6072, we get 294.
Append the next digit (3) from the dividend to 294 and continue with: 2943 / 642

Let's proceed to step 6:
2943 divided by 642 is 4 with a remainder of 375.
Put 4 as the next digit of the answer. 
Result so far: 294.0
If we take 2568 away from 2943, we end up with 375.
Grab the next digit (0) from the dividend, add it to 375, then carry on: 3750 / 642

Going ahead to step 7:
642 goes into 3750 5 times with a remainder of 540.
The next digit of our result is 5. 
Result so far: 2945.0
If we take 3210 away from 3750, we end up with 540.
Bring next digit (4) of the dividend behind the 540 and repeat the process: 5404 / 642

Advancing to step 8:
642 goes into 5404 8 times with a remainder of 268.
Write down 8 as next digit of the result. 
Result so far: 29458.0
Subtract 5136 from 5404 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 9:
642 goes into 2680 4 times with a remainder of 112.
Use 4 as the next digit of our solution. 
Result so far: 29458.4
Subtract 2568 from 2680 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 10:
1120 divided by 642 is 1 with a remainder of 478.
The number 1 becomes the next digit in our result. 
Result so far: 29458.41
Subtract 642 from 1120 to get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

On to step 11:
642 can be fit into 4780 7 times, resulting in a remainder of 286.
Write down 7 as next digit of the result. 
Result so far: 29458.417
The remainder is 286 after subtracting 4494 from 4780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 12:
If we divide 2860 by 642, we get 4 and a remainder of 292.
Use 4 as the next digit of our solution. 
Result so far: 29458.4174
If we subtract 2568 from 2860, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 13:
642 goes into 2920 4 times with a remainder of 352.
Use 4 as the next digit of our solution. 
Result so far: 29458.41744
Subtract 2568 from 2920 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

After the division, we end up with 29458.41744 and a remainder of 0.000352.
