66320768 ÷ 346 
Let's see how many times 346 fits into 66320768.

Step 1:
The number 346 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 346

Advancing to step 2:
66 divided by 346 is 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Bring next digit (3) of the dividend behind the 66 and repeat the process: 663 / 346

Going ahead to step 3:
346 goes into 663 1 times with a remainder of 317.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 317 after subtracting 346 from 663.
Include the next digit (2) from the dividend after 317, then repeat: 3172 / 346

Moving on to step 4:
If we divide 3172 by 346, we get 9 and a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 3114 from 3172 leaves us with 58.
Grab the next digit (0) from the dividend, add it to 58, then carry on: 580 / 346

Going ahead to step 5:
If we divide 580 by 346, we get 1 and a remainder of 234.
The next digit of our result is 1. 
Result so far: 191.0
Subtracting 346 from 580 leaves us with 234.
Grab the next digit (7) from the dividend, add it to 234, then carry on: 2347 / 346

Moving on to step 6:
346 can be fit into 2347 6 times, resulting in a remainder of 271.
The number 6 becomes the next digit in our result. 
Result so far: 1916.0
If we take 2076 away from 2347, we end up with 271.
Grab the next digit (6) from the dividend, add it to 271, then carry on: 2716 / 346

Step 7:
The number 346 fits into 2716 7 times, leaving a remainder of 294.
Record the quotient 7 as the next digit in the result. 
Result so far: 19167.0
If we take 2422 away from 2716, we end up with 294.
Bring next digit (8) of the dividend behind the 294 and repeat the process: 2948 / 346

Let's proceed to step 8:
2948 divided by 346 is 8 with a remainder of 180.
The number 8 becomes the next digit in our result. 
Result so far: 191678.0
Subtract 2768 from 2948 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 9:
346 goes into 1800 5 times with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 191678.5
If we take 1730 away from 1800, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
If we divide 700 by 346, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 191678.52
If we subtract 692 from 700, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
346 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 191678.52
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
When dividing 800 by 346, we get 2 with a remainder of 108.
Use 2 as the next digit of our solution. 
Result so far: 191678.5202
Subtract 692 from 800 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 13:
When dividing 1080 by 346, we get 3 with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 191678.52023
If we take 1038 away from 1080, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 14:
420 divided by 346 is 1 with a remainder of 74.
Record the quotient 1 as the next digit in the result. 
Result so far: 191678.520231
Subtracting 346 from 420 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 15:
346 goes into 740 2 times with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 191678.5202312
Subtract 692 from 740 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 16:
If we divide 480 by 346, we get 1 and a remainder of 134.
Record the quotient 1 as the next digit in the result. 
Result so far: 191678.52023121
Subtract 346 from 480 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

The final result is 191678.52023121 with a remainder of 1.34e-07.
