We're dividing 78144947 by 917 
The aim is to understand the frequency of 917 in 78144947.

Step 1:
7 divided by 917 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 917

Going ahead to step 2:
When dividing 78 by 917, we get 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (1) from the dividend, add it to 78, then carry on: 781 / 917

Moving on to step 3:
When dividing 781 by 917, we get 0 with a remainder of 781.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 781, we get 781.
Append the next digit (4) from the dividend to 781 and continue with: 7814 / 917

On to step 4:
7814 divided by 917 is 8 with a remainder of 478.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 478 after subtracting 7336 from 7814.
Include the next digit (4) from the dividend after 478, then repeat: 4784 / 917

Let's proceed to step 5:
When dividing 4784 by 917, we get 5 with a remainder of 199.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
Deduct 4585 from 4784 and we're left with 199.
Fetch the next digit (9) from the dividend, attach it to 199 and continue: 1999 / 917

Step 6:
The number 917 fits into 1999 2 times, leaving a remainder of 165.
Write down 2 as next digit of the result. 
Result so far: 852.0
Subtracting 1834 from 1999 leaves us with 165.
Append the next digit (4) from the dividend to 165 and continue with: 1654 / 917

Advancing to step 7:
1654 divided by 917 is 1 with a remainder of 737.
Write down 1 as next digit of the result. 
Result so far: 8521.0
Subtracting 917 from 1654 leaves us with 737.
Grab the next digit (7) from the dividend, add it to 737, then carry on: 7377 / 917

Going ahead to step 8:
When dividing 7377 by 917, we get 8 with a remainder of 41.
Write down 8 as next digit of the result. 
Result so far: 85218.0
Subtracting 7336 from 7377 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 9:
If we divide 410 by 917, we get 0 and a remainder of 410.
Write down 0 as next digit of the result. 
Result so far: 85218.0
If we take 0 away from 410, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 10:
If we divide 4100 by 917, we get 4 and a remainder of 432.
The next digit of our result is 4. 
Result so far: 85218.04
Subtract 3668 from 4100 to get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Advancing to step 11:
4320 divided by 917 is 4 with a remainder of 652.
Record the quotient 4 as the next digit in the result. 
Result so far: 85218.044
Subtract 3668 from 4320 to get 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

The final result is 85218.044 with a remainder of 0.0652.
