We're dividing 91731035 by 774 
The aim is to understand the frequency of 774 in 91731035.

Advancing to step 1:
If we divide 9 by 774, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 774

Moving on to step 2:
The number 774 fits into 91 0 times, leaving a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Grab the next digit (7) from the dividend, add it to 91, then carry on: 917 / 774

Let's proceed to step 3:
917 divided by 774 is 1 with a remainder of 143.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 774 from 917, we get 143.
Grab the next digit (3) from the dividend, add it to 143, then carry on: 1433 / 774

Let's proceed to step 4:
774 goes into 1433 1 times with a remainder of 659.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 774 from 1433 to get 659.
Fetch the next digit (1) from the dividend, attach it to 659 and continue: 6591 / 774

Moving on to step 5:
774 goes into 6591 8 times with a remainder of 399.
Write down 8 as next digit of the result. 
Result so far: 118.0
If we take 6192 away from 6591, we end up with 399.
Include the next digit (0) from the dividend after 399, then repeat: 3990 / 774

Going ahead to step 6:
The number 774 fits into 3990 5 times, leaving a remainder of 120.
Use 5 as the next digit of our solution. 
Result so far: 1185.0
If we subtract 3870 from 3990, we get 120.
Take the next digit (3) from the dividend and append it to 120, then repeat: 1203 / 774

Advancing to step 7:
1203 divided by 774 is 1 with a remainder of 429.
Use 1 as the next digit of our solution. 
Result so far: 11851.0
The remainder is 429 after subtracting 774 from 1203.
Take the next digit (5) from the dividend and append it to 429, then repeat: 4295 / 774

On to step 8:
774 can be fit into 4295 5 times, resulting in a remainder of 425.
Use 5 as the next digit of our solution. 
Result so far: 118515.0
If we subtract 3870 from 4295, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Going ahead to step 9:
4250 divided by 774 is 5 with a remainder of 380.
Use 5 as the next digit of our solution. 
Result so far: 118515.5
If we take 3870 away from 4250, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 10:
If we divide 3800 by 774, we get 4 and a remainder of 704.
The number 4 becomes the next digit in our result. 
Result so far: 118515.54
Subtract 3096 from 3800 to get 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Advancing to step 11:
774 goes into 7040 9 times with a remainder of 74.
The next digit of our result is 9. 
Result so far: 118515.549
Deduct 6966 from 7040 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.

Moving on to step 12:
774 can be fit into 740 0 times, resulting in a remainder of 740.
The next digit of our result is 0. 
Result so far: 118515.549
If we take 0 away from 740, we end up with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Going ahead to step 13:
774 can be fit into 7400 9 times, resulting in a remainder of 434.
Record the quotient 9 as the next digit in the result. 
Result so far: 118515.54909
Subtracting 6966 from 7400 leaves us with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

On to step 14:
774 can be fit into 4340 5 times, resulting in a remainder of 470.
Put 5 as the next digit of the answer. 
Result so far: 118515.549095
The remainder is 470 after subtracting 3870 from 4340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 15:
The number 774 fits into 4700 6 times, leaving a remainder of 56.
The next digit of our result is 6. 
Result so far: 118515.5490956
Subtracting 4644 from 4700 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 16:
774 goes into 560 0 times with a remainder of 560.
The next digit of our result is 0. 
Result so far: 118515.5490956
Subtract 0 from 560 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

The final result is 118515.5490956 with a remainder of 5.6e-07.
