12946387 divided by 770 
The aim is to understand the frequency of 770 in 12946387.

On to step 1:
770 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 770

Advancing to step 2:
If we divide 12 by 770, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 770

Moving on to step 3:
When dividing 129 by 770, we get 0 with a remainder of 129.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 129, we get 129.
Include the next digit (4) from the dividend after 129, then repeat: 1294 / 770

Going ahead to step 4:
770 goes into 1294 1 times with a remainder of 524.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 770 away from 1294, we end up with 524.
Bring next digit (6) of the dividend behind the 524 and repeat the process: 5246 / 770

Step 5:
770 goes into 5246 6 times with a remainder of 626.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 4620 away from 5246, we end up with 626.
Fetch the next digit (3) from the dividend, attach it to 626 and continue: 6263 / 770

On to step 6:
6263 divided by 770 is 8 with a remainder of 103.
The number 8 becomes the next digit in our result. 
Result so far: 168.0
The remainder is 103 after subtracting 6160 from 6263.
Fetch the next digit (8) from the dividend, attach it to 103 and continue: 1038 / 770

On to step 7:
If we divide 1038 by 770, we get 1 and a remainder of 268.
Use 1 as the next digit of our solution. 
Result so far: 1681.0
If we take 770 away from 1038, we end up with 268.
Include the next digit (7) from the dividend after 268, then repeat: 2687 / 770

Let's proceed to step 8:
If we divide 2687 by 770, we get 3 and a remainder of 377.
Use 3 as the next digit of our solution. 
Result so far: 16813.0
If we take 2310 away from 2687, we end up with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Let's proceed to step 9:
If we divide 3770 by 770, we get 4 and a remainder of 690.
Use 4 as the next digit of our solution. 
Result so far: 16813.4
The remainder is 690 after subtracting 3080 from 3770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Moving on to step 10:
The number 770 fits into 6900 8 times, leaving a remainder of 740.
The next digit of our result is 8. 
Result so far: 16813.48
If we take 6160 away from 6900, we end up with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Let's proceed to step 11:
The number 770 fits into 7400 9 times, leaving a remainder of 470.
The number 9 becomes the next digit in our result. 
Result so far: 16813.489
The remainder is 470 after subtracting 6930 from 7400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 12:
When dividing 4700 by 770, we get 6 with a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 16813.4896
The remainder is 80 after subtracting 4620 from 4700.
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 13:
800 divided by 770 is 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 16813.48961
If we take 770 away from 800, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
770 can be fit into 300 0 times, resulting in a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 16813.48961
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 15:
The number 770 fits into 3000 3 times, leaving a remainder of 690.
Write down 3 as next digit of the result. 
Result so far: 16813.4896103
If we subtract 2310 from 3000, we get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Advancing to step 16:
When dividing 6900 by 770, we get 8 with a remainder of 740.
Write down 8 as next digit of the result. 
Result so far: 16813.48961038
Subtract 6160 from 6900 to get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

The final result is 16813.48961038 with a remainder of 7.4e-07.
