We look at the division of 82961224 by 770 
The aim is to understand the frequency of 770 in 82961224.

On to step 1:
When dividing 8 by 770, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 770

Moving on to step 2:
770 goes into 82 0 times with a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Append the next digit (9) from the dividend to 82 and continue with: 829 / 770

Going ahead to step 3:
When dividing 829 by 770, we get 1 with a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 770 from 829 leaves us with 59.
Append the next digit (6) from the dividend to 59 and continue with: 596 / 770

Step 4:
770 goes into 596 0 times with a remainder of 596.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 596 to get 596.
Fetch the next digit (1) from the dividend, attach it to 596 and continue: 5961 / 770

On to step 5:
770 can be fit into 5961 7 times, resulting in a remainder of 571.
Use 7 as the next digit of our solution. 
Result so far: 107.0
Deduct 5390 from 5961 and we're left with 571.
Grab the next digit (2) from the dividend, add it to 571, then carry on: 5712 / 770

Step 6:
770 can be fit into 5712 7 times, resulting in a remainder of 322.
Record the quotient 7 as the next digit in the result. 
Result so far: 1077.0
The remainder is 322 after subtracting 5390 from 5712.
Take the next digit (2) from the dividend and append it to 322, then repeat: 3222 / 770

Advancing to step 7:
770 can be fit into 3222 4 times, resulting in a remainder of 142.
Write down 4 as next digit of the result. 
Result so far: 10774.0
If we subtract 3080 from 3222, we get 142.
Append the next digit (4) from the dividend to 142 and continue with: 1424 / 770

Going ahead to step 8:
When dividing 1424 by 770, we get 1 with a remainder of 654.
Record the quotient 1 as the next digit in the result. 
Result so far: 107741.0
The remainder is 654 after subtracting 770 from 1424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Moving on to step 9:
When dividing 6540 by 770, we get 8 with a remainder of 380.
Put 8 as the next digit of the answer. 
Result so far: 107741.8
The remainder is 380 after subtracting 6160 from 6540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 10:
The number 770 fits into 3800 4 times, leaving a remainder of 720.
Use 4 as the next digit of our solution. 
Result so far: 107741.84
If we take 3080 away from 3800, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 11:
770 goes into 7200 9 times with a remainder of 270.
The next digit of our result is 9. 
Result so far: 107741.849
If we subtract 6930 from 7200, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 12:
770 can be fit into 2700 3 times, resulting in a remainder of 390.
The number 3 becomes the next digit in our result. 
Result so far: 107741.8493
Deduct 2310 from 2700 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 13:
When dividing 3900 by 770, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 107741.84935
Deduct 3850 from 3900 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
770 can be fit into 500 0 times, resulting in a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 107741.84935
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 15:
When dividing 5000 by 770, we get 6 with a remainder of 380.
Put 6 as the next digit of the answer. 
Result so far: 107741.8493506
The remainder is 380 after subtracting 4620 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 16:
The number 770 fits into 3800 4 times, leaving a remainder of 720.
Put 4 as the next digit of the answer. 
Result so far: 107741.84935064
Subtracting 3080 from 3800 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Our division results in 107741.84935064 with a remaining 7.2e-07.
