Let's divide 81189378 by 717
The aim is to understand the frequency of 717 in 81189378.

On to step 1:
The number 717 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 717

Going ahead to step 2:
81 divided by 717 is 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Bring next digit (1) of the dividend behind the 81 and repeat the process: 811 / 717

Going ahead to step 3:
The number 717 fits into 811 1 times, leaving a remainder of 94.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 717 from 811 to get 94.
Append the next digit (8) from the dividend to 94 and continue with: 948 / 717

Moving on to step 4:
717 goes into 948 1 times with a remainder of 231.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 717 away from 948, we end up with 231.
Bring next digit (9) of the dividend behind the 231 and repeat the process: 2319 / 717

Advancing to step 5:
The number 717 fits into 2319 3 times, leaving a remainder of 168.
The next digit of our result is 3. 
Result so far: 113.0
If we take 2151 away from 2319, we end up with 168.
Bring next digit (3) of the dividend behind the 168 and repeat the process: 1683 / 717

Let's proceed to step 6:
The number 717 fits into 1683 2 times, leaving a remainder of 249.
Use 2 as the next digit of our solution. 
Result so far: 1132.0
Subtract 1434 from 1683 to get 249.
Grab the next digit (7) from the dividend, add it to 249, then carry on: 2497 / 717

Going ahead to step 7:
If we divide 2497 by 717, we get 3 and a remainder of 346.
Record the quotient 3 as the next digit in the result. 
Result so far: 11323.0
The remainder is 346 after subtracting 2151 from 2497.
Grab the next digit (8) from the dividend, add it to 346, then carry on: 3468 / 717

Advancing to step 8:
3468 divided by 717 is 4 with a remainder of 600.
Put 4 as the next digit of the answer. 
Result so far: 113234.0
The remainder is 600 after subtracting 2868 from 3468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 9:
717 goes into 6000 8 times with a remainder of 264.
Put 8 as the next digit of the answer. 
Result so far: 113234.8
Subtracting 5736 from 6000 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 10:
If we divide 2640 by 717, we get 3 and a remainder of 489.
Use 3 as the next digit of our solution. 
Result so far: 113234.83
If we take 2151 away from 2640, we end up with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Moving on to step 11:
4890 divided by 717 is 6 with a remainder of 588.
The next digit of our result is 6. 
Result so far: 113234.836
If we take 4302 away from 4890, we end up with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Step 12:
If we divide 5880 by 717, we get 8 and a remainder of 144.
Use 8 as the next digit of our solution. 
Result so far: 113234.8368
Deduct 5736 from 5880 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 13:
The number 717 fits into 1440 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 113234.83682
Subtracting 1434 from 1440 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
60 divided by 717 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 113234.83682
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 15:
717 goes into 600 0 times with a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 113234.83682
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Our division results in 113234.83682 with a remaining 6e-06.
