We're dividing 79578715 by 973 
The aim is to understand the frequency of 973 in 79578715.

On to step 1:
If we divide 7 by 973, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 973

Advancing to step 2:
973 goes into 79 0 times with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Include the next digit (5) from the dividend after 79, then repeat: 795 / 973

Step 3:
973 can be fit into 795 0 times, resulting in a remainder of 795.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 795, we get 795.
Include the next digit (7) from the dividend after 795, then repeat: 7957 / 973

Moving on to step 4:
973 goes into 7957 8 times with a remainder of 173.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 173 after subtracting 7784 from 7957.
Bring next digit (8) of the dividend behind the 173 and repeat the process: 1738 / 973

Moving on to step 5:
973 goes into 1738 1 times with a remainder of 765.
The next digit of our result is 1. 
Result so far: 81.0
If we take 973 away from 1738, we end up with 765.
Fetch the next digit (7) from the dividend, attach it to 765 and continue: 7657 / 973

Going ahead to step 6:
When dividing 7657 by 973, we get 7 with a remainder of 846.
Write down 7 as next digit of the result. 
Result so far: 817.0
If we subtract 6811 from 7657, we get 846.
Grab the next digit (1) from the dividend, add it to 846, then carry on: 8461 / 973

Step 7:
If we divide 8461 by 973, we get 8 and a remainder of 677.
The number 8 becomes the next digit in our result. 
Result so far: 8178.0
If we take 7784 away from 8461, we end up with 677.
Fetch the next digit (5) from the dividend, attach it to 677 and continue: 6775 / 973

Let's proceed to step 8:
973 can be fit into 6775 6 times, resulting in a remainder of 937.
Record the quotient 6 as the next digit in the result. 
Result so far: 81786.0
Subtract 5838 from 6775 to get 937.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9370, and continue the process.

On to step 9:
9370 divided by 973 is 9 with a remainder of 613.
Put 9 as the next digit of the answer. 
Result so far: 81786.9
Deduct 8757 from 9370 and we're left with 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

Step 10:
973 can be fit into 6130 6 times, resulting in a remainder of 292.
Use 6 as the next digit of our solution. 
Result so far: 81786.96
Subtract 5838 from 6130 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 11:
If we divide 2920 by 973, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 81786.963
If we subtract 2919 from 2920, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
973 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 81786.963
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
973 goes into 100 0 times with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 81786.963
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 81786.963, with a leftover of 0.0001.
