66403802 ÷ 101 
We want to divide 66403802 by 101.

Going ahead to step 1:
101 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 101

Step 2:
101 can be fit into 66 0 times, resulting in a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 101

Step 3:
When dividing 664 by 101, we get 6 with a remainder of 58.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 606 from 664 to get 58.
Fetch the next digit (0) from the dividend, attach it to 58 and continue: 580 / 101

Going ahead to step 4:
When dividing 580 by 101, we get 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 65.0
Subtract 505 from 580 to get 75.
Bring next digit (3) of the dividend behind the 75 and repeat the process: 753 / 101

Let's proceed to step 5:
When dividing 753 by 101, we get 7 with a remainder of 46.
Use 7 as the next digit of our solution. 
Result so far: 657.0
If we subtract 707 from 753, we get 46.
Bring next digit (8) of the dividend behind the 46 and repeat the process: 468 / 101

Let's proceed to step 6:
101 goes into 468 4 times with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 6574.0
If we take 404 away from 468, we end up with 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 101

Step 7:
If we divide 640 by 101, we get 6 and a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 65746.0
If we take 606 away from 640, we end up with 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 101

Moving on to step 8:
If we divide 342 by 101, we get 3 and a remainder of 39.
The next digit of our result is 3. 
Result so far: 657463.0
Deduct 303 from 342 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 9:
The number 101 fits into 390 3 times, leaving a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 657463.3
The remainder is 87 after subtracting 303 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 10:
The number 101 fits into 870 8 times, leaving a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 657463.38
Deduct 808 from 870 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 11:
101 goes into 620 6 times with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 657463.386
Subtracting 606 from 620 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
101 goes into 140 1 times with a remainder of 39.
The next digit of our result is 1. 
Result so far: 657463.3861
If we take 101 away from 140, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 13:
390 divided by 101 is 3 with a remainder of 87.
Use 3 as the next digit of our solution. 
Result so far: 657463.38613
If we subtract 303 from 390, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 14:
The number 101 fits into 870 8 times, leaving a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 657463.386138
If we subtract 808 from 870, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 15:
101 can be fit into 620 6 times, resulting in a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 657463.3861386
Subtract 606 from 620 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 16:
101 can be fit into 140 1 times, resulting in a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 657463.38613861
The remainder is 39 after subtracting 101 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 657463.38613861 and a remainder of 3.9e-08.
