12310189 ÷ 766 
We want to figure out the number of times 12310189 can be divided by 766.

Moving on to step 1:
If we divide 1 by 766, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 766

Let's proceed to step 2:
If we divide 12 by 766, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 766

Moving on to step 3:
The number 766 fits into 123 0 times, leaving a remainder of 123.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 123, we get 123.
Bring next digit (1) of the dividend behind the 123 and repeat the process: 1231 / 766

Advancing to step 4:
When dividing 1231 by 766, we get 1 with a remainder of 465.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 465 after subtracting 766 from 1231.
Include the next digit (0) from the dividend after 465, then repeat: 4650 / 766

Let's proceed to step 5:
If we divide 4650 by 766, we get 6 and a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 4596 from 4650 and we're left with 54.
Take the next digit (1) from the dividend and append it to 54, then repeat: 541 / 766

Step 6:
The number 766 fits into 541 0 times, leaving a remainder of 541.
Use 0 as the next digit of our solution. 
Result so far: 160.0
If we subtract 0 from 541, we get 541.
Grab the next digit (8) from the dividend, add it to 541, then carry on: 5418 / 766

Advancing to step 7:
766 can be fit into 5418 7 times, resulting in a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 1607.0
The remainder is 56 after subtracting 5362 from 5418.
Take the next digit (9) from the dividend and append it to 56, then repeat: 569 / 766

Step 8:
766 can be fit into 569 0 times, resulting in a remainder of 569.
The next digit of our result is 0. 
Result so far: 16070.0
The remainder is 569 after subtracting 0 from 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Advancing to step 9:
The number 766 fits into 5690 7 times, leaving a remainder of 328.
Use 7 as the next digit of our solution. 
Result so far: 16070.7
The remainder is 328 after subtracting 5362 from 5690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 10:
If we divide 3280 by 766, we get 4 and a remainder of 216.
Use 4 as the next digit of our solution. 
Result so far: 16070.74
Subtracting 3064 from 3280 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 11:
766 goes into 2160 2 times with a remainder of 628.
The next digit of our result is 2. 
Result so far: 16070.742
Subtracting 1532 from 2160 leaves us with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Let's proceed to step 12:
766 can be fit into 6280 8 times, resulting in a remainder of 152.
The next digit of our result is 8. 
Result so far: 16070.7428
Subtracting 6128 from 6280 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 13:
1520 divided by 766 is 1 with a remainder of 754.
The number 1 becomes the next digit in our result. 
Result so far: 16070.74281
If we take 766 away from 1520, we end up with 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Step 14:
The number 766 fits into 7540 9 times, leaving a remainder of 646.
Write down 9 as next digit of the result. 
Result so far: 16070.742819
Subtract 6894 from 7540 to get 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Going ahead to step 15:
766 goes into 6460 8 times with a remainder of 332.
The number 8 becomes the next digit in our result. 
Result so far: 16070.7428198
If we subtract 6128 from 6460, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Moving on to step 16:
The number 766 fits into 3320 4 times, leaving a remainder of 256.
Record the quotient 4 as the next digit in the result. 
Result so far: 16070.74281984
If we take 3064 away from 3320, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Our division results in 16070.74281984 with a remaining 2.56e-07.
