We look at the division of 49464749 by 642 
We want to figure out the number of times 49464749 can be divided by 642.

Step 1:
When dividing 4 by 642, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 642

Step 2:
If we divide 49 by 642, we get 0 and a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Fetch the next digit (4) from the dividend, attach it to 49 and continue: 494 / 642

Let's proceed to step 3:
If we divide 494 by 642, we get 0 and a remainder of 494.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 494 after subtracting 0 from 494.
Take the next digit (6) from the dividend and append it to 494, then repeat: 4946 / 642

Step 4:
When dividing 4946 by 642, we get 7 with a remainder of 452.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 4494 from 4946 to get 452.
Fetch the next digit (4) from the dividend, attach it to 452 and continue: 4524 / 642

On to step 5:
642 goes into 4524 7 times with a remainder of 30.
The next digit of our result is 7. 
Result so far: 77.0
The remainder is 30 after subtracting 4494 from 4524.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 642

Advancing to step 6:
The number 642 fits into 307 0 times, leaving a remainder of 307.
The next digit of our result is 0. 
Result so far: 770.0
If we subtract 0 from 307, we get 307.
Include the next digit (4) from the dividend after 307, then repeat: 3074 / 642

Moving on to step 7:
The number 642 fits into 3074 4 times, leaving a remainder of 506.
Write down 4 as next digit of the result. 
Result so far: 7704.0
If we subtract 2568 from 3074, we get 506.
Include the next digit (9) from the dividend after 506, then repeat: 5069 / 642

Let's proceed to step 8:
642 goes into 5069 7 times with a remainder of 575.
Put 7 as the next digit of the answer. 
Result so far: 77047.0
The remainder is 575 after subtracting 4494 from 5069.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Advancing to step 9:
642 can be fit into 5750 8 times, resulting in a remainder of 614.
Use 8 as the next digit of our solution. 
Result so far: 77047.8
Deduct 5136 from 5750 and we're left with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Moving on to step 10:
When dividing 6140 by 642, we get 9 with a remainder of 362.
Record the quotient 9 as the next digit in the result. 
Result so far: 77047.89
Subtracting 5778 from 6140 leaves us with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Let's proceed to step 11:
642 goes into 3620 5 times with a remainder of 410.
Write down 5 as next digit of the result. 
Result so far: 77047.895
If we take 3210 away from 3620, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 12:
The number 642 fits into 4100 6 times, leaving a remainder of 248.
Use 6 as the next digit of our solution. 
Result so far: 77047.8956
Subtract 3852 from 4100 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 13:
When dividing 2480 by 642, we get 3 with a remainder of 554.
The next digit of our result is 3. 
Result so far: 77047.89563
The remainder is 554 after subtracting 1926 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Moving on to step 14:
The number 642 fits into 5540 8 times, leaving a remainder of 404.
Use 8 as the next digit of our solution. 
Result so far: 77047.895638
Deduct 5136 from 5540 and we're left with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Going ahead to step 15:
The number 642 fits into 4040 6 times, leaving a remainder of 188.
Use 6 as the next digit of our solution. 
Result so far: 77047.8956386
Subtract 3852 from 4040 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 16:
The number 642 fits into 1880 2 times, leaving a remainder of 596.
Record the quotient 2 as the next digit in the result. 
Result so far: 77047.89563862
If we take 1284 away from 1880, we end up with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Our division results in 77047.89563862 with a remaining 5.96e-07.
