66766821 ÷ 235 
Our goal is to divide 66766821 by 235.

Let's proceed to step 1:
235 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 235

On to step 2:
If we divide 66 by 235, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (7) from the dividend to 66 and continue with: 667 / 235

Let's proceed to step 3:
667 divided by 235 is 2 with a remainder of 197.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 470 away from 667, we end up with 197.
Take the next digit (6) from the dividend and append it to 197, then repeat: 1976 / 235

Going ahead to step 4:
The number 235 fits into 1976 8 times, leaving a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we subtract 1880 from 1976, we get 96.
Grab the next digit (6) from the dividend, add it to 96, then carry on: 966 / 235

On to step 5:
If we divide 966 by 235, we get 4 and a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 284.0
Subtract 940 from 966 to get 26.
Include the next digit (8) from the dividend after 26, then repeat: 268 / 235

Advancing to step 6:
235 can be fit into 268 1 times, resulting in a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 2841.0
Subtracting 235 from 268 leaves us with 33.
Bring next digit (2) of the dividend behind the 33 and repeat the process: 332 / 235

On to step 7:
235 can be fit into 332 1 times, resulting in a remainder of 97.
Use 1 as the next digit of our solution. 
Result so far: 28411.0
If we take 235 away from 332, we end up with 97.
Append the next digit (1) from the dividend to 97 and continue with: 971 / 235

Step 8:
235 goes into 971 4 times with a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 284114.0
If we subtract 940 from 971, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 9:
310 divided by 235 is 1 with a remainder of 75.
The number 1 becomes the next digit in our result. 
Result so far: 284114.1
If we subtract 235 from 310, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 10:
235 can be fit into 750 3 times, resulting in a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 284114.13
If we take 705 away from 750, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 11:
When dividing 450 by 235, we get 1 with a remainder of 215.
Use 1 as the next digit of our solution. 
Result so far: 284114.131
If we subtract 235 from 450, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 12:
The number 235 fits into 2150 9 times, leaving a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 284114.1319
Subtract 2115 from 2150 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 13:
If we divide 350 by 235, we get 1 and a remainder of 115.
Record the quotient 1 as the next digit in the result. 
Result so far: 284114.13191
Deduct 235 from 350 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 14:
1150 divided by 235 is 4 with a remainder of 210.
Write down 4 as next digit of the result. 
Result so far: 284114.131914
Subtracting 940 from 1150 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 15:
The number 235 fits into 2100 8 times, leaving a remainder of 220.
The next digit of our result is 8. 
Result so far: 284114.1319148
If we subtract 1880 from 2100, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 16:
235 can be fit into 2200 9 times, resulting in a remainder of 85.
Record the quotient 9 as the next digit in the result. 
Result so far: 284114.13191489
Subtract 2115 from 2200 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final outcome is 284114.13191489, with a leftover of 8.5e-08.
