We look at the division of 189316 by 77 
The aim is to understand the frequency of 77 in 189316.

Let's proceed to step 1:
77 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 77

Going ahead to step 2:
The number 77 fits into 18 0 times, leaving a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 77

Going ahead to step 3:
If we divide 189 by 77, we get 2 and a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 35 after subtracting 154 from 189.
Bring next digit (3) of the dividend behind the 35 and repeat the process: 353 / 77

Moving on to step 4:
The number 77 fits into 353 4 times, leaving a remainder of 45.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we take 308 away from 353, we end up with 45.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 77

Advancing to step 5:
The number 77 fits into 451 5 times, leaving a remainder of 66.
Put 5 as the next digit of the answer. 
Result so far: 245.0
Deduct 385 from 451 and we're left with 66.
Fetch the next digit (6) from the dividend, attach it to 66 and continue: 666 / 77

Going ahead to step 6:
The number 77 fits into 666 8 times, leaving a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 2458.0
Subtracting 616 from 666 leaves us 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.

Moving on to step 7:
When dividing 500 by 77, we get 6 with a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 2458.6
The remainder is 38 after subtracting 462 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
77 goes into 380 4 times with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 2458.64
The remainder is 72 after subtracting 308 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 9:
The number 77 fits into 720 9 times, leaving a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 2458.649
Subtract 693 from 720 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 10:
77 can be fit into 270 3 times, resulting in a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 2458.6493
Subtract 231 from 270 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 11:
77 can be fit into 390 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 2458.64935
Subtracting 385 from 390 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
When dividing 50 by 77, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 2458.64935
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
77 can be fit into 500 6 times, resulting in a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 2458.6493506
Subtract 462 from 500 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 14:
77 goes into 380 4 times with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 2458.64935064
Deduct 308 from 380 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 2458.64935064, with a leftover of 7.2e-08.
