Let's divide 38779555 by 642
We're looking to find how many times 642 goes into 38779555.

On to step 1:
If we divide 3 by 642, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 642

Let's proceed to step 2:
642 can be fit into 38 0 times, resulting in a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Take the next digit (7) from the dividend and append it to 38, then repeat: 387 / 642

On to step 3:
642 goes into 387 0 times with a remainder of 387.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 387 to get 387.
Fetch the next digit (7) from the dividend, attach it to 387 and continue: 3877 / 642

On to step 4:
The number 642 fits into 3877 6 times, leaving a remainder of 25.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 3852 away from 3877, we end up with 25.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 642

Moving on to step 5:
When dividing 259 by 642, we get 0 with a remainder of 259.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
If we subtract 0 from 259, we get 259.
Append the next digit (5) from the dividend to 259 and continue with: 2595 / 642

Advancing to step 6:
The number 642 fits into 2595 4 times, leaving a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 604.0
If we subtract 2568 from 2595, we get 27.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 642

Let's proceed to step 7:
275 divided by 642 is 0 with a remainder of 275.
Use 0 as the next digit of our solution. 
Result so far: 6040.0
Deduct 0 from 275 and we're left with 275.
Fetch the next digit (5) from the dividend, attach it to 275 and continue: 2755 / 642

Let's proceed to step 8:
If we divide 2755 by 642, we get 4 and a remainder of 187.
Put 4 as the next digit of the answer. 
Result so far: 60404.0
Subtracting 2568 from 2755 leaves us with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Moving on to step 9:
1870 divided by 642 is 2 with a remainder of 586.
The next digit of our result is 2. 
Result so far: 60404.2
The remainder is 586 after subtracting 1284 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Let's proceed to step 10:
The number 642 fits into 5860 9 times, leaving a remainder of 82.
Use 9 as the next digit of our solution. 
Result so far: 60404.29
Deduct 5778 from 5860 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 11:
If we divide 820 by 642, we get 1 and a remainder of 178.
Put 1 as the next digit of the answer. 
Result so far: 60404.291
Subtract 642 from 820 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 12:
1780 divided by 642 is 2 with a remainder of 496.
Write down 2 as next digit of the result. 
Result so far: 60404.2912
Subtract 1284 from 1780 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 13:
If we divide 4960 by 642, we get 7 and a remainder of 466.
Write down 7 as next digit of the result. 
Result so far: 60404.29127
The remainder is 466 after subtracting 4494 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Advancing to step 14:
The number 642 fits into 4660 7 times, leaving a remainder of 166.
The next digit of our result is 7. 
Result so far: 60404.291277
Subtracting 4494 from 4660 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Our division results in 60404.291277 with a remaining 1.66e-05.
