1828291 divided by 770 
The aim is to understand the frequency of 770 in 1828291.

Advancing to step 1:
If we divide 1 by 770, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 770

Moving on to step 2:
18 divided by 770 is 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 770

On to step 3:
770 goes into 182 0 times with a remainder of 182.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 182, we end up with 182.
Include the next digit (8) from the dividend after 182, then repeat: 1828 / 770

Going ahead to step 4:
If we divide 1828 by 770, we get 2 and a remainder of 288.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1540 from 1828 leaves us with 288.
Grab the next digit (2) from the dividend, add it to 288, then carry on: 2882 / 770

Going ahead to step 5:
770 goes into 2882 3 times with a remainder of 572.
Use 3 as the next digit of our solution. 
Result so far: 23.0
The remainder is 572 after subtracting 2310 from 2882.
Grab the next digit (9) from the dividend, add it to 572, then carry on: 5729 / 770

On to step 6:
770 goes into 5729 7 times with a remainder of 339.
The number 7 becomes the next digit in our result. 
Result so far: 237.0
Deduct 5390 from 5729 and we're left with 339.
Fetch the next digit (1) from the dividend, attach it to 339 and continue: 3391 / 770

Moving on to step 7:
770 goes into 3391 4 times with a remainder of 311.
Use 4 as the next digit of our solution. 
Result so far: 2374.0
If we take 3080 away from 3391, we end up with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Let's proceed to step 8:
770 can be fit into 3110 4 times, resulting in a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 2374.4
Subtracting 3080 from 3110 leaves us 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.

Advancing to step 9:
If we divide 300 by 770, we get 0 and a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 2374.4
Deduct 0 from 300 and we're left 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.

Advancing to step 10:
If we divide 3000 by 770, we get 3 and a remainder of 690.
The number 3 becomes the next digit in our result. 
Result so far: 2374.403
The remainder is 690 after subtracting 2310 from 3000.
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 11:
If we divide 6900 by 770, we get 8 and a remainder of 740.
The number 8 becomes the next digit in our result. 
Result so far: 2374.4038
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.

Moving on to step 12:
The number 770 fits into 7400 9 times, leaving a remainder of 470.
The next digit of our result is 9. 
Result so far: 2374.40389
If we subtract 6930 from 7400, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

On to step 13:
When dividing 4700 by 770, we get 6 with a remainder of 80.
The next digit of our result is 6. 
Result so far: 2374.403896
Deduct 4620 from 4700 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.

Advancing to step 14:
800 divided by 770 is 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 2374.4038961
Deduct 770 from 800 and we're left 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.

Advancing to step 15:
The number 770 fits into 300 0 times, leaving a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 2374.4038961
Deduct 0 from 300 and we're left 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.

The final result is 2374.4038961 with a remainder of 3e-07.
