We look at the division of 77898207 by 973 
The aim is to understand the frequency of 973 in 77898207.

Let's proceed 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
Deduct 0 from 7 and we're left with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 973

Moving on to step 2:
If we divide 77 by 973, we get 0 and a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Take the next digit (8) from the dividend and append it to 77, then repeat: 778 / 973

Let's proceed to step 3:
If we divide 778 by 973, we get 0 and a remainder of 778.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 778 and we're left with 778.
Bring next digit (9) of the dividend behind the 778 and repeat the process: 7789 / 973

Going ahead to step 4:
7789 divided by 973 is 8 with a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 7784 from 7789 leaves us with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 973

On to step 5:
973 goes into 58 0 times with a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 80.0
The remainder is 58 after subtracting 0 from 58.
Fetch the next digit (2) from the dividend, attach it to 58 and continue: 582 / 973

Going ahead to step 6:
The number 973 fits into 582 0 times, leaving a remainder of 582.
The number 0 becomes the next digit in our result. 
Result so far: 800.0
The remainder is 582 after subtracting 0 from 582.
Fetch the next digit (0) from the dividend, attach it to 582 and continue: 5820 / 973

On to step 7:
The number 973 fits into 5820 5 times, leaving a remainder of 955.
Use 5 as the next digit of our solution. 
Result so far: 8005.0
Subtracting 4865 from 5820 leaves us with 955.
Grab the next digit (7) from the dividend, add it to 955, then carry on: 9557 / 973

Let's proceed to step 8:
When dividing 9557 by 973, we get 9 with a remainder of 800.
Use 9 as the next digit of our solution. 
Result so far: 80059.0
The remainder is 800 after subtracting 8757 from 9557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Step 9:
8000 divided by 973 is 8 with a remainder of 216.
The number 8 becomes the next digit in our result. 
Result so far: 80059.8
Subtract 7784 from 8000 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 10:
973 can be fit into 2160 2 times, resulting in a remainder of 214.
Record the quotient 2 as the next digit in the result. 
Result so far: 80059.82
If we take 1946 away from 2160, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 11:
The number 973 fits into 2140 2 times, leaving a remainder of 194.
The number 2 becomes the next digit in our result. 
Result so far: 80059.822
If we take 1946 away from 2140, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Our division results in 80059.822 with a remaining 0.0194.
