We're dividing 66358249 by 774 
The aim is to understand the frequency of 774 in 66358249.

Step 1:
774 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 774

Let's proceed to step 2:
When dividing 66 by 774, we get 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (3) from the dividend and append it to 66, then repeat: 663 / 774

Going ahead to step 3:
774 goes into 663 0 times with a remainder of 663.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 663, we get 663.
Include the next digit (5) from the dividend after 663, then repeat: 6635 / 774

Step 4:
If we divide 6635 by 774, we get 8 and a remainder of 443.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 6192 away from 6635, we end up with 443.
Fetch the next digit (8) from the dividend, attach it to 443 and continue: 4438 / 774

Let's proceed to step 5:
The number 774 fits into 4438 5 times, leaving a remainder of 568.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
If we take 3870 away from 4438, we end up with 568.
Grab the next digit (2) from the dividend, add it to 568, then carry on: 5682 / 774

Moving on to step 6:
If we divide 5682 by 774, we get 7 and a remainder of 264.
Use 7 as the next digit of our solution. 
Result so far: 857.0
Subtract 5418 from 5682 to get 264.
Bring next digit (4) of the dividend behind the 264 and repeat the process: 2644 / 774

Step 7:
774 goes into 2644 3 times with a remainder of 322.
Put 3 as the next digit of the answer. 
Result so far: 8573.0
The remainder is 322 after subtracting 2322 from 2644.
Append the next digit (9) from the dividend to 322 and continue with: 3229 / 774

Step 8:
If we divide 3229 by 774, we get 4 and a remainder of 133.
The next digit of our result is 4. 
Result so far: 85734.0
Subtracting 3096 from 3229 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Let's proceed to step 9:
774 can be fit into 1330 1 times, resulting in a remainder of 556.
Write down 1 as next digit of the result. 
Result so far: 85734.1
Subtract 774 from 1330 to get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Step 10:
The number 774 fits into 5560 7 times, leaving a remainder of 142.
The number 7 becomes the next digit in our result. 
Result so far: 85734.17
Subtracting 5418 from 5560 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 11:
The number 774 fits into 1420 1 times, leaving a remainder of 646.
Write down 1 as next digit of the result. 
Result so far: 85734.171
If we subtract 774 from 1420, we get 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Moving on to step 12:
774 can be fit into 6460 8 times, resulting in a remainder of 268.
Put 8 as the next digit of the answer. 
Result so far: 85734.1718
Deduct 6192 from 6460 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 13:
If we divide 2680 by 774, we get 3 and a remainder of 358.
Record the quotient 3 as the next digit in the result. 
Result so far: 85734.17183
The remainder is 358 after subtracting 2322 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Advancing to step 14:
If we divide 3580 by 774, we get 4 and a remainder of 484.
Use 4 as the next digit of our solution. 
Result so far: 85734.171834
The remainder is 484 after subtracting 3096 from 3580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Going ahead to step 15:
When dividing 4840 by 774, we get 6 with a remainder of 196.
The next digit of our result is 6. 
Result so far: 85734.1718346
If we subtract 4644 from 4840, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 16:
If we divide 1960 by 774, we get 2 and a remainder of 412.
The number 2 becomes the next digit in our result. 
Result so far: 85734.17183462
If we take 1548 away from 1960, we end up with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

In conclusion, the division gives 85734.17183462 with a balance of 4.12e-07.
