We're dividing 943280 by 77 
The aim is to understand the frequency of 77 in 943280.

Let's proceed to step 1:
77 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 77

Let's proceed to step 2:
77 can be fit into 94 1 times, resulting in a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 77 away from 94, we end up with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 77

Going ahead to step 3:
When dividing 173 by 77, we get 2 with a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 154 from 173 leaves us with 19.
Bring next digit (2) of the dividend behind the 19 and repeat the process: 192 / 77

Going ahead to step 4:
77 can be fit into 192 2 times, resulting in a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
Subtracting 154 from 192 leaves us with 38.
Append the next digit (8) from the dividend to 38 and continue with: 388 / 77

Moving on to step 5:
If we divide 388 by 77, we get 5 and a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 1225.0
The remainder is 3 after subtracting 385 from 388.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 77

Moving on to step 6:
77 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 12250.0
Subtracting 0 from 30 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.

Let's proceed to step 7:
The number 77 fits into 300 3 times, leaving a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 12250.3
If we take 231 away from 300, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 8:
If we divide 690 by 77, we get 8 and a remainder of 74.
Put 8 as the next digit of the answer. 
Result so far: 12250.38
Subtracting 616 from 690 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 9:
When dividing 740 by 77, we get 9 with a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 12250.389
Subtract 693 from 740 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 10:
470 divided by 77 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 12250.3896
Subtracting 462 from 470 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
When dividing 80 by 77, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 12250.38961
Deduct 77 from 80 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 12:
When dividing 30 by 77, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 12250.38961
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
When dividing 300 by 77, we get 3 with a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 12250.3896103
The remainder is 69 after subtracting 231 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 14:
77 goes into 690 8 times with a remainder of 74.
Use 8 as the next digit of our solution. 
Result so far: 12250.38961038
Deduct 616 from 690 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Our division results in 12250.38961038 with a remaining 7.4e-08.
