Let's divide 66595020 by 642
Let's see how many times 642 fits into 66595020.

Going ahead to step 1:
The number 642 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 642

Advancing to step 2:
When dividing 66 by 642, we get 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Include the next digit (5) from the dividend after 66, then repeat: 665 / 642

On to step 3:
When dividing 665 by 642, we get 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 642 from 665 and we're left with 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 642

Let's proceed to step 4:
The number 642 fits into 239 0 times, leaving a remainder of 239.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 239 to get 239.
Fetch the next digit (5) from the dividend, attach it to 239 and continue: 2395 / 642

Moving on to step 5:
The number 642 fits into 2395 3 times, leaving a remainder of 469.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
Deduct 1926 from 2395 and we're left with 469.
Append the next digit (0) from the dividend to 469 and continue with: 4690 / 642

Let's proceed to step 6:
The number 642 fits into 4690 7 times, leaving a remainder of 196.
The next digit of our result is 7. 
Result so far: 1037.0
Deduct 4494 from 4690 and we're left with 196.
Bring next digit (2) of the dividend behind the 196 and repeat the process: 1962 / 642

Step 7:
The number 642 fits into 1962 3 times, leaving a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 10373.0
Deduct 1926 from 1962 and we're left with 36.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 642

Let's proceed to step 8:
360 divided by 642 is 0 with a remainder of 360.
The number 0 becomes the next digit in our result. 
Result so far: 103730.0
If we subtract 0 from 360, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 9:
642 can be fit into 3600 5 times, resulting in a remainder of 390.
Use 5 as the next digit of our solution. 
Result so far: 103730.5
Subtracting 3210 from 3600 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 10:
The number 642 fits into 3900 6 times, leaving a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 103730.56
Subtract 3852 from 3900 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
642 goes into 480 0 times with a remainder of 480.
The next digit of our result is 0. 
Result so far: 103730.56
If we subtract 0 from 480, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 12:
When dividing 4800 by 642, we get 7 with a remainder of 306.
Use 7 as the next digit of our solution. 
Result so far: 103730.5607
Subtracting 4494 from 4800 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 13:
The number 642 fits into 3060 4 times, leaving a remainder of 492.
Use 4 as the next digit of our solution. 
Result so far: 103730.56074
Subtracting 2568 from 3060 leaves us with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Advancing to step 14:
642 goes into 4920 7 times with a remainder of 426.
Put 7 as the next digit of the answer. 
Result so far: 103730.560747
Subtract 4494 from 4920 to get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

On to step 15:
642 can be fit into 4260 6 times, resulting in a remainder of 408.
Put 6 as the next digit of the answer. 
Result so far: 103730.5607476
Deduct 3852 from 4260 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 16:
642 can be fit into 4080 6 times, resulting in a remainder of 228.
The number 6 becomes the next digit in our result. 
Result so far: 103730.56074766
Subtracting 3852 from 4080 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

After the division, we end up with 103730.56074766 and a remainder of 2.28e-07.
