65899466 ÷ 345 
Our goal is to divide 65899466 by 345.

Advancing to step 1:
If we divide 6 by 345, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 345

Moving on to step 2:
345 can be fit into 65 0 times, resulting in a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Take the next digit (8) from the dividend and append it to 65, then repeat: 658 / 345

On to step 3:
345 can be fit into 658 1 times, resulting in a remainder of 313.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 345 from 658 leaves us with 313.
Fetch the next digit (9) from the dividend, attach it to 313 and continue: 3139 / 345

Advancing to step 4:
The number 345 fits into 3139 9 times, leaving a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 34 after subtracting 3105 from 3139.
Bring next digit (9) of the dividend behind the 34 and repeat the process: 349 / 345

Step 5:
The number 345 fits into 349 1 times, leaving a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 191.0
Deduct 345 from 349 and we're left with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 345

Step 6:
345 goes into 44 0 times with a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 1910.0
The remainder is 44 after subtracting 0 from 44.
Fetch the next digit (6) from the dividend, attach it to 44 and continue: 446 / 345

Step 7:
345 goes into 446 1 times with a remainder of 101.
The next digit of our result is 1. 
Result so far: 19101.0
Deduct 345 from 446 and we're left with 101.
Append the next digit (6) from the dividend to 101 and continue with: 1016 / 345

Moving on to step 8:
345 can be fit into 1016 2 times, resulting in a remainder of 326.
Put 2 as the next digit of the answer. 
Result so far: 191012.0
If we subtract 690 from 1016, we get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Moving on to step 9:
If we divide 3260 by 345, we get 9 and a remainder of 155.
Put 9 as the next digit of the answer. 
Result so far: 191012.9
The remainder is 155 after subtracting 3105 from 3260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 10:
345 goes into 1550 4 times with a remainder of 170.
Put 4 as the next digit of the answer. 
Result so far: 191012.94
If we take 1380 away from 1550, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 11:
1700 divided by 345 is 4 with a remainder of 320.
Put 4 as the next digit of the answer. 
Result so far: 191012.944
The remainder is 320 after subtracting 1380 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The quotient of the division is 191012.944, and the remainder is 0.032.
