We look at the division of 73587696 by 123 
The aim is to understand the frequency of 123 in 73587696.

On to step 1:
7 divided by 123 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.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 123

Advancing to step 2:
123 goes into 73 0 times with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Grab the next digit (5) from the dividend, add it to 73, then carry on: 735 / 123

Moving on to step 3:
When dividing 735 by 123, we get 5 with a remainder of 120.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 615 from 735 and we're left with 120.
Grab the next digit (8) from the dividend, add it to 120, then carry on: 1208 / 123

Moving on to step 4:
123 can be fit into 1208 9 times, resulting in a remainder of 101.
Use 9 as the next digit of our solution. 
Result so far: 59.0
If we subtract 1107 from 1208, we get 101.
Bring next digit (7) of the dividend behind the 101 and repeat the process: 1017 / 123

Let's proceed to step 5:
If we divide 1017 by 123, we get 8 and a remainder of 33.
Put 8 as the next digit of the answer. 
Result so far: 598.0
If we take 984 away from 1017, we end up with 33.
Grab the next digit (6) from the dividend, add it to 33, then carry on: 336 / 123

Step 6:
When dividing 336 by 123, we get 2 with a remainder of 90.
Record the quotient 2 as the next digit in the result. 
Result so far: 5982.0
Deduct 246 from 336 and we're left with 90.
Bring next digit (9) of the dividend behind the 90 and repeat the process: 909 / 123

Going ahead to step 7:
If we divide 909 by 123, we get 7 and a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 59827.0
If we take 861 away from 909, we end up with 48.
Grab the next digit (6) from the dividend, add it to 48, then carry on: 486 / 123

Moving on to step 8:
The number 123 fits into 486 3 times, leaving a remainder of 117.
Write down 3 as next digit of the result. 
Result so far: 598273.0
The remainder is 117 after subtracting 369 from 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

On to step 9:
123 can be fit into 1170 9 times, resulting in a remainder of 63.
The number 9 becomes the next digit in our result. 
Result so far: 598273.9
Subtracting 1107 from 1170 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 10:
123 can be fit into 630 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 598273.95
Subtracting 615 from 630 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
If we divide 150 by 123, we get 1 and a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 598273.951
If we subtract 123 from 150, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 12:
When dividing 270 by 123, we get 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 598273.9512
If we subtract 246 from 270, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
240 divided by 123 is 1 with a remainder of 117.
Use 1 as the next digit of our solution. 
Result so far: 598273.95121
If we subtract 123 from 240, we get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

On to step 14:
123 goes into 1170 9 times with a remainder of 63.
Write down 9 as next digit of the result. 
Result so far: 598273.951219
The remainder is 63 after subtracting 1107 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 15:
When dividing 630 by 123, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 598273.9512195
Subtract 615 from 630 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 16:
123 goes into 150 1 times with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 598273.95121951
The remainder is 27 after subtracting 123 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

In conclusion, the division gives 598273.95121951 with a balance of 2.7e-08.
