66140435 ÷ 802 
We want to divide 66140435 by 802.

On to step 1:
If we divide 6 by 802, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 802

Moving on to step 2:
When dividing 66 by 802, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 802

On to step 3:
If we divide 661 by 802, we get 0 and a remainder of 661.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 661, we end up with 661.
Take the next digit (4) from the dividend and append it to 661, then repeat: 6614 / 802

Advancing to step 4:
802 goes into 6614 8 times with a remainder of 198.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 6416 from 6614, we get 198.
Bring next digit (0) of the dividend behind the 198 and repeat the process: 1980 / 802

Advancing to step 5:
802 can be fit into 1980 2 times, resulting in a remainder of 376.
Put 2 as the next digit of the answer. 
Result so far: 82.0
If we take 1604 away from 1980, we end up with 376.
Take the next digit (4) from the dividend and append it to 376, then repeat: 3764 / 802

Advancing to step 6:
If we divide 3764 by 802, we get 4 and a remainder of 556.
Use 4 as the next digit of our solution. 
Result so far: 824.0
If we take 3208 away from 3764, we end up with 556.
Append the next digit (3) from the dividend to 556 and continue with: 5563 / 802

Moving on to step 7:
802 goes into 5563 6 times with a remainder of 751.
The number 6 becomes the next digit in our result. 
Result so far: 8246.0
If we subtract 4812 from 5563, we get 751.
Take the next digit (5) from the dividend and append it to 751, then repeat: 7515 / 802

Let's proceed to step 8:
If we divide 7515 by 802, we get 9 and a remainder of 297.
The next digit of our result is 9. 
Result so far: 82469.0
Subtract 7218 from 7515 to get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Going ahead to step 9:
802 goes into 2970 3 times with a remainder of 564.
Put 3 as the next digit of the answer. 
Result so far: 82469.3
Subtracting 2406 from 2970 leaves us with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Going ahead to step 10:
802 can be fit into 5640 7 times, resulting in a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 82469.37
If we subtract 5614 from 5640, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 11:
When dividing 260 by 802, we get 0 with a remainder of 260.
The next digit of our result is 0. 
Result so far: 82469.37
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 12:
2600 divided by 802 is 3 with a remainder of 194.
Use 3 as the next digit of our solution. 
Result so far: 82469.3703
Subtracting 2406 from 2600 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 13:
1940 divided by 802 is 2 with a remainder of 336.
Put 2 as the next digit of the answer. 
Result so far: 82469.37032
Deduct 1604 from 1940 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 14:
3360 divided by 802 is 4 with a remainder of 152.
Use 4 as the next digit of our solution. 
Result so far: 82469.370324
Subtract 3208 from 3360 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 15:
If we divide 1520 by 802, we get 1 and a remainder of 718.
Use 1 as the next digit of our solution. 
Result so far: 82469.3703241
If we subtract 802 from 1520, we get 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Moving on to step 16:
If we divide 7180 by 802, we get 8 and a remainder of 764.
Put 8 as the next digit of the answer. 
Result so far: 82469.37032418
The remainder is 764 after subtracting 6416 from 7180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Our division results in 82469.37032418 with a remaining 7.64e-07.
