Let's divide 18033209 by 770
The aim is to understand the frequency of 770 in 18033209.

On to step 1:
If we divide 1 by 770, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 770

Step 2:
The number 770 fits into 18 0 times, leaving a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 770

Step 3:
The number 770 fits into 180 0 times, leaving a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 180 leaves us with 180.
Include the next digit (3) from the dividend after 180, then repeat: 1803 / 770

On to step 4:
770 can be fit into 1803 2 times, resulting in a remainder of 263.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 1540 away from 1803, we end up with 263.
Include the next digit (3) from the dividend after 263, then repeat: 2633 / 770

Going ahead to step 5:
The number 770 fits into 2633 3 times, leaving a remainder of 323.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we subtract 2310 from 2633, we get 323.
Append the next digit (2) from the dividend to 323 and continue with: 3232 / 770

Moving on to step 6:
3232 divided by 770 is 4 with a remainder of 152.
Write down 4 as next digit of the result. 
Result so far: 234.0
Subtracting 3080 from 3232 leaves us with 152.
Fetch the next digit (0) from the dividend, attach it to 152 and continue: 1520 / 770

Advancing to step 7:
When dividing 1520 by 770, we get 1 with a remainder of 750.
Write down 1 as next digit of the result. 
Result so far: 2341.0
Deduct 770 from 1520 and we're left with 750.
Append the next digit (9) from the dividend to 750 and continue with: 7509 / 770

Going ahead to step 8:
If we divide 7509 by 770, we get 9 and a remainder of 579.
Record the quotient 9 as the next digit in the result. 
Result so far: 23419.0
The remainder is 579 after subtracting 6930 from 7509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

On to step 9:
When dividing 5790 by 770, we get 7 with a remainder of 400.
Record the quotient 7 as the next digit in the result. 
Result so far: 23419.7
The remainder is 400 after subtracting 5390 from 5790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 10:
770 can be fit into 4000 5 times, resulting in a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 23419.75
Subtract 3850 from 4000 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 11:
770 goes into 1500 1 times with a remainder of 730.
Write down 1 as next digit of the result. 
Result so far: 23419.751
The remainder is 730 after subtracting 770 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Step 12:
770 goes into 7300 9 times with a remainder of 370.
The number 9 becomes the next digit in our result. 
Result so far: 23419.7519
Subtract 6930 from 7300 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 13:
If we divide 3700 by 770, we get 4 and a remainder of 620.
The number 4 becomes the next digit in our result. 
Result so far: 23419.75194
Subtracting 3080 from 3700 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

On to step 14:
6200 divided by 770 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 23419.751948
Subtract 6160 from 6200 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 15:
400 divided by 770 is 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 23419.751948
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 16:
When dividing 4000 by 770, we get 5 with a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 23419.75194805
If we take 3850 away from 4000, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The quotient of the division is 23419.75194805, and the remainder is 1.5e-07.
