65516059 ÷ 124 
The aim is to understand the frequency of 124 in 65516059.

Step 1:
6 divided by 124 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 124

Step 2:
When dividing 65 by 124, we get 0 with a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Bring next digit (5) of the dividend behind the 65 and repeat the process: 655 / 124

On to step 3:
When dividing 655 by 124, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 620 from 655 leaves us with 35.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 124

On to step 4:
351 divided by 124 is 2 with a remainder of 103.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
Subtract 248 from 351 to get 103.
Include the next digit (6) from the dividend after 103, then repeat: 1036 / 124

Step 5:
124 can be fit into 1036 8 times, resulting in a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 528.0
The remainder is 44 after subtracting 992 from 1036.
Fetch the next digit (0) from the dividend, attach it to 44 and continue: 440 / 124

Advancing to step 6:
When dividing 440 by 124, we get 3 with a remainder of 68.
Record the quotient 3 as the next digit in the result. 
Result so far: 5283.0
The remainder is 68 after subtracting 372 from 440.
Include the next digit (5) from the dividend after 68, then repeat: 685 / 124

Let's proceed to step 7:
The number 124 fits into 685 5 times, leaving a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 52835.0
Deduct 620 from 685 and we're left with 65.
Fetch the next digit (9) from the dividend, attach it to 65 and continue: 659 / 124

Step 8:
124 can be fit into 659 5 times, resulting in a remainder of 39.
Put 5 as the next digit of the answer. 
Result so far: 528355.0
Deduct 620 from 659 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 9:
124 goes into 390 3 times with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 528355.3
Subtracting 372 from 390 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
If we divide 180 by 124, we get 1 and a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 528355.31
If we take 124 away from 180, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 11:
124 can be fit into 560 4 times, resulting in a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 528355.314
If we take 496 away from 560, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
If we divide 640 by 124, we get 5 and a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 528355.3145
Subtract 620 from 640 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
124 can be fit into 200 1 times, resulting in a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 528355.31451
Subtracting 124 from 200 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 14:
760 divided by 124 is 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 528355.314516
If we subtract 744 from 760, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 15:
The number 124 fits into 160 1 times, leaving a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 528355.3145161
If we subtract 124 from 160, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 16:
If we divide 360 by 124, we get 2 and a remainder of 112.
Write down 2 as next digit of the result. 
Result so far: 528355.31451612
Subtracting 248 from 360 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final outcome is 528355.31451612, with a leftover of 1.12e-07.
