We're dividing 91112668 by 393 
The aim is to understand the frequency of 393 in 91112668.

Advancing to step 1:
The number 393 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 393

Advancing to step 2:
393 goes into 91 0 times with a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Append the next digit (1) from the dividend to 91 and continue with: 911 / 393

Advancing to step 3:
When dividing 911 by 393, we get 2 with a remainder of 125.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 786 from 911 leaves us with 125.
Fetch the next digit (1) from the dividend, attach it to 125 and continue: 1251 / 393

Advancing to step 4:
393 goes into 1251 3 times with a remainder of 72.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Deduct 1179 from 1251 and we're left with 72.
Fetch the next digit (2) from the dividend, attach it to 72 and continue: 722 / 393

Step 5:
When dividing 722 by 393, we get 1 with a remainder of 329.
Write down 1 as next digit of the result. 
Result so far: 231.0
Subtract 393 from 722 to get 329.
Bring next digit (6) of the dividend behind the 329 and repeat the process: 3296 / 393

Step 6:
If we divide 3296 by 393, we get 8 and a remainder of 152.
Use 8 as the next digit of our solution. 
Result so far: 2318.0
Subtract 3144 from 3296 to get 152.
Include the next digit (6) from the dividend after 152, then repeat: 1526 / 393

Going ahead to step 7:
1526 divided by 393 is 3 with a remainder of 347.
The number 3 becomes the next digit in our result. 
Result so far: 23183.0
Deduct 1179 from 1526 and we're left with 347.
Take the next digit (8) from the dividend and append it to 347, then repeat: 3478 / 393

On to step 8:
393 can be fit into 3478 8 times, resulting in a remainder of 334.
Put 8 as the next digit of the answer. 
Result so far: 231838.0
The remainder is 334 after subtracting 3144 from 3478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Step 9:
The number 393 fits into 3340 8 times, leaving a remainder of 196.
Record the quotient 8 as the next digit in the result. 
Result so far: 231838.8
Subtracting 3144 from 3340 leaves us with 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 10:
If we divide 1960 by 393, we get 4 and a remainder of 388.
Use 4 as the next digit of our solution. 
Result so far: 231838.84
Subtract 1572 from 1960 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 11:
3880 divided by 393 is 9 with a remainder of 343.
The number 9 becomes the next digit in our result. 
Result so far: 231838.849
Subtract 3537 from 3880 to get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

On to step 12:
The number 393 fits into 3430 8 times, leaving a remainder of 286.
Use 8 as the next digit of our solution. 
Result so far: 231838.8498
Subtract 3144 from 3430 to get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Advancing to step 13:
393 goes into 2860 7 times with a remainder of 109.
Put 7 as the next digit of the answer. 
Result so far: 231838.84987
The remainder is 109 after subtracting 2751 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 14:
If we divide 1090 by 393, we get 2 and a remainder of 304.
The next digit of our result is 2. 
Result so far: 231838.849872
Subtracting 786 from 1090 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 15:
3040 divided by 393 is 7 with a remainder of 289.
Record the quotient 7 as the next digit in the result. 
Result so far: 231838.8498727
The remainder is 289 after subtracting 2751 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Let's proceed to step 16:
2890 divided by 393 is 7 with a remainder of 139.
Write down 7 as next digit of the result. 
Result so far: 231838.84987277
If we take 2751 away from 2890, we end up with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

The final outcome is 231838.84987277, with a leftover of 1.39e-07.
