72756861 ÷ 120 
The aim is to understand the frequency of 120 in 72756861.

Moving on to step 1:
120 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 120

Going ahead to step 2:
120 goes into 72 0 times with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Grab the next digit (7) from the dividend, add it to 72, then carry on: 727 / 120

Step 3:
If we divide 727 by 120, we get 6 and a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 720 from 727 leaves us with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 120

Step 4:
120 can be fit into 75 0 times, resulting in a remainder of 75.
The next digit of our result is 0. 
Result so far: 60.0
Subtract 0 from 75 to get 75.
Grab the next digit (6) from the dividend, add it to 75, then carry on: 756 / 120

Going ahead to step 5:
756 divided by 120 is 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 606.0
Subtracting 720 from 756 leaves us with 36.
Take the next digit (8) from the dividend and append it to 36, then repeat: 368 / 120

On to step 6:
120 goes into 368 3 times with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 6063.0
The remainder is 8 after subtracting 360 from 368.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 120

Step 7:
120 goes into 86 0 times with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 60630.0
Subtracting 0 from 86 leaves us with 86.
Include the next digit (1) from the dividend after 86, then repeat: 861 / 120

Going ahead to step 8:
The number 120 fits into 861 7 times, leaving a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 606307.0
Subtract 840 from 861 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
120 can be fit into 210 1 times, resulting in a remainder of 90.
Write down 1 as next digit of the result. 
Result so far: 606307.1
If we take 120 away from 210, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
The number 120 fits into 900 7 times, leaving a remainder of 60.
Put 7 as the next digit of the answer. 
Result so far: 606307.17
Deduct 840 from 900 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
If we divide 600 by 120, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 606307.175
If we subtract 600 from 600, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
If we divide 0 by 120, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 606307.175
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
120 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 606307.175
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 606307.175, with a leftover of 0.0.
