86918642 ÷ 120 
The aim is to understand the frequency of 120 in 86918642.

On to step 1:
When dividing 8 by 120, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 120

Let's proceed to step 2:
The number 120 fits into 86 0 times, leaving a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Bring next digit (9) of the dividend behind the 86 and repeat the process: 869 / 120

Advancing to step 3:
120 goes into 869 7 times with a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 29 after subtracting 840 from 869.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 120

Advancing to step 4:
If we divide 291 by 120, we get 2 and a remainder of 51.
Put 2 as the next digit of the answer. 
Result so far: 72.0
If we take 240 away from 291, we end up with 51.
Append the next digit (8) from the dividend to 51 and continue with: 518 / 120

On to step 5:
If we divide 518 by 120, we get 4 and a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 724.0
If we take 480 away from 518, we end up with 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 120

On to step 6:
120 goes into 386 3 times with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 7243.0
If we subtract 360 from 386, we get 26.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 120

Let's proceed to step 7:
120 goes into 264 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 72432.0
Deduct 240 from 264 and we're left with 24.
Fetch the next digit (2) from the dividend, attach it to 24 and continue: 242 / 120

Moving on to step 8:
If we divide 242 by 120, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 724322.0
Subtract 240 from 242 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
120 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 724322.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
120 can be fit into 200 1 times, resulting in a remainder of 80.
The next digit of our result is 1. 
Result so far: 724322.01
If we subtract 120 from 200, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
800 divided by 120 is 6 with a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 724322.016
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
120 goes into 800 6 times with a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 724322.0166
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

In conclusion, the division gives 724322.0166 with a balance of 0.0008.
