We're dividing 66400333 by 355 
We want to divide 66400333 by 355.

Let's proceed to step 1:
If we divide 6 by 355, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 355

Let's proceed to step 2:
The number 355 fits into 66 0 times, leaving a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 355

On to step 3:
If we divide 664 by 355, we get 1 and a remainder of 309.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 355 from 664, we get 309.
Bring next digit (0) of the dividend behind the 309 and repeat the process: 3090 / 355

Going ahead to step 4:
355 can be fit into 3090 8 times, resulting in a remainder of 250.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we take 2840 away from 3090, we end up with 250.
Grab the next digit (0) from the dividend, add it to 250, then carry on: 2500 / 355

Step 5:
The number 355 fits into 2500 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 187.0
If we subtract 2485 from 2500, we get 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 355

Going ahead to step 6:
If we divide 153 by 355, we get 0 and a remainder of 153.
The next digit of our result is 0. 
Result so far: 1870.0
If we subtract 0 from 153, we get 153.
Append the next digit (3) from the dividend to 153 and continue with: 1533 / 355

Going ahead to step 7:
If we divide 1533 by 355, we get 4 and a remainder of 113.
The next digit of our result is 4. 
Result so far: 18704.0
Subtracting 1420 from 1533 leaves us with 113.
Fetch the next digit (3) from the dividend, attach it to 113 and continue: 1133 / 355

Going ahead to step 8:
1133 divided by 355 is 3 with a remainder of 68.
The next digit of our result is 3. 
Result so far: 187043.0
Deduct 1065 from 1133 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 9:
355 can be fit into 680 1 times, resulting in a remainder of 325.
Put 1 as the next digit of the answer. 
Result so far: 187043.1
Deduct 355 from 680 and we're left with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Let's proceed to step 10:
If we divide 3250 by 355, we get 9 and a remainder of 55.
Use 9 as the next digit of our solution. 
Result so far: 187043.19
If we subtract 3195 from 3250, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 11:
When dividing 550 by 355, we get 1 with a remainder of 195.
Use 1 as the next digit of our solution. 
Result so far: 187043.191
If we take 355 away from 550, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Going ahead to step 12:
If we divide 1950 by 355, we get 5 and a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 187043.1915
The remainder is 175 after subtracting 1775 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 13:
355 can be fit into 1750 4 times, resulting in a remainder of 330.
Record the quotient 4 as the next digit in the result. 
Result so far: 187043.19154
The remainder is 330 after subtracting 1420 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 14:
355 can be fit into 3300 9 times, resulting in a remainder of 105.
Put 9 as the next digit of the answer. 
Result so far: 187043.191549
Subtract 3195 from 3300 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 15:
355 can be fit into 1050 2 times, resulting in a remainder of 340.
Use 2 as the next digit of our solution. 
Result so far: 187043.1915492
Subtracting 710 from 1050 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 16:
If we divide 3400 by 355, we get 9 and a remainder of 205.
Write down 9 as next digit of the result. 
Result so far: 187043.19154929
The remainder is 205 after subtracting 3195 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

After the division, we end up with 187043.19154929 and a remainder of 2.05e-07.
