We look at the division of 853363 by 77 
The aim is to understand the frequency of 77 in 853363.

Moving on to step 1:
When dividing 8 by 77, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 77

Let's proceed to step 2:
When dividing 85 by 77, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 77 from 85 leaves us with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 77

Step 3:
The number 77 fits into 83 1 times, leaving a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 77 from 83 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 77

On to step 4:
If we divide 63 by 77, we get 0 and a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
If we subtract 0 from 63, we get 63.
Include the next digit (6) from the dividend after 63, then repeat: 636 / 77

Advancing to step 5:
When dividing 636 by 77, we get 8 with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 1108.0
If we take 616 away from 636, we end up with 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 77

Let's proceed to step 6:
203 divided by 77 is 2 with a remainder of 49.
Use 2 as the next digit of our solution. 
Result so far: 11082.0
The remainder is 49 after subtracting 154 from 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
When dividing 490 by 77, we get 6 with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 11082.6
If we take 462 away from 490, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
When dividing 280 by 77, we get 3 with a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 11082.63
Subtracting 231 from 280 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 9:
When dividing 490 by 77, we get 6 with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 11082.636
Subtracting 462 from 490 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
77 goes into 280 3 times with a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 11082.6363
Subtract 231 from 280 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 11:
The number 77 fits into 490 6 times, leaving a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 11082.63636
Deduct 462 from 490 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 12:
If we divide 280 by 77, we get 3 and a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 11082.636363
The remainder is 49 after subtracting 231 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 13:
If we divide 490 by 77, we get 6 and a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 11082.6363636
Subtract 462 from 490 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 14:
The number 77 fits into 280 3 times, leaving a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 11082.63636363
If we subtract 231 from 280, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The quotient of the division is 11082.63636363, and the remainder is 4.9e-08.
