We divide 329769 by 77
The aim is to understand the frequency of 77 in 329769.

On to step 1:
77 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 77

Advancing to step 2:
When dividing 32 by 77, we get 0 with a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 32 leaves us with 32.
Append the next digit (9) from the dividend to 32 and continue with: 329 / 77

Step 3:
77 can be fit into 329 4 times, resulting in a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 21 after subtracting 308 from 329.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 77

Going ahead to step 4:
If we divide 217 by 77, we get 2 and a remainder of 63.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtract 154 from 217 to get 63.
Append the next digit (6) from the dividend to 63 and continue with: 636 / 77

Let's proceed to step 5:
If we divide 636 by 77, we get 8 and a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 428.0
If we subtract 616 from 636, we get 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 77

On to step 6:
The number 77 fits into 209 2 times, leaving a remainder of 55.
Put 2 as the next digit of the answer. 
Result so far: 4282.0
The remainder is 55 after subtracting 154 from 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 7:
77 can be fit into 550 7 times, resulting in a remainder of 11.
The next digit of our result is 7. 
Result so far: 4282.7
If we take 539 away from 550, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
If we divide 110 by 77, we get 1 and a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 4282.71
Subtracting 77 from 110 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 9:
77 can be fit into 330 4 times, resulting in a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 4282.714
If we subtract 308 from 330, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
77 goes into 220 2 times with a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 4282.7142
If we subtract 154 from 220, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 11:
When dividing 660 by 77, we get 8 with a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 4282.71428
Subtracting 616 from 660 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 12:
The number 77 fits into 440 5 times, leaving a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 4282.714285
Subtract 385 from 440 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 13:
77 goes into 550 7 times with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 4282.7142857
Deduct 539 from 550 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 14:
If we divide 110 by 77, we get 1 and a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 4282.71428571
The remainder is 33 after subtracting 77 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final result is 4282.71428571 with a remainder of 3.3e-08.
