We look at the division of 23883657 by 770 
The aim is to understand the frequency of 770 in 23883657.

Let's proceed to step 1:
When dividing 2 by 770, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 770

On to step 2:
770 can be fit into 23 0 times, resulting in a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 770

On to step 3:
If we divide 238 by 770, we get 0 and a remainder of 238.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 238 to get 238.
Fetch the next digit (8) from the dividend, attach it to 238 and continue: 2388 / 770

Advancing to step 4:
The number 770 fits into 2388 3 times, leaving a remainder of 78.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 2310 from 2388, we get 78.
Take the next digit (3) from the dividend and append it to 78, then repeat: 783 / 770

Step 5:
783 divided by 770 is 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtract 770 from 783 to get 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 770

Going ahead to step 6:
770 goes into 136 0 times with a remainder of 136.
The next digit of our result is 0. 
Result so far: 310.0
Deduct 0 from 136 and we're left with 136.
Append the next digit (5) from the dividend to 136 and continue with: 1365 / 770

Advancing to step 7:
If we divide 1365 by 770, we get 1 and a remainder of 595.
The number 1 becomes the next digit in our result. 
Result so far: 3101.0
The remainder is 595 after subtracting 770 from 1365.
Include the next digit (7) from the dividend after 595, then repeat: 5957 / 770

Going ahead to step 8:
770 goes into 5957 7 times with a remainder of 567.
Put 7 as the next digit of the answer. 
Result so far: 31017.0
The remainder is 567 after subtracting 5390 from 5957.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Advancing to step 9:
770 can be fit into 5670 7 times, resulting in a remainder of 280.
The next digit of our result is 7. 
Result so far: 31017.7
Deduct 5390 from 5670 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 10:
When dividing 2800 by 770, we get 3 with a remainder of 490.
Put 3 as the next digit of the answer. 
Result so far: 31017.73
The remainder is 490 after subtracting 2310 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 11:
If we divide 4900 by 770, we get 6 and a remainder of 280.
Record the quotient 6 as the next digit in the result. 
Result so far: 31017.736
Subtracting 4620 from 4900 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 12:
When dividing 2800 by 770, we get 3 with a remainder of 490.
The next digit of our result is 3. 
Result so far: 31017.7363
If we take 2310 away from 2800, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 13:
4900 divided by 770 is 6 with a remainder of 280.
The number 6 becomes the next digit in our result. 
Result so far: 31017.73636
Subtracting 4620 from 4900 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 14:
The number 770 fits into 2800 3 times, leaving a remainder of 490.
Record the quotient 3 as the next digit in the result. 
Result so far: 31017.736363
If we subtract 2310 from 2800, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 15:
When dividing 4900 by 770, we get 6 with a remainder of 280.
The next digit of our result is 6. 
Result so far: 31017.7363636
The remainder is 280 after subtracting 4620 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 16:
770 goes into 2800 3 times with a remainder of 490.
The number 3 becomes the next digit in our result. 
Result so far: 31017.73636363
If we subtract 2310 from 2800, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

After the division, we end up with 31017.73636363 and a remainder of 4.9e-07.
