We divide 120990 by 64
The aim is to understand the frequency of 64 in 120990.

Let's proceed to step 1:
If we divide 1 by 64, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 64

Step 2:
If we divide 12 by 64, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 64

Let's proceed to step 3:
64 goes into 120 1 times with a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 64 from 120 and we're left with 56.
Include the next digit (9) from the dividend after 56, then repeat: 569 / 64

Advancing to step 4:
569 divided by 64 is 8 with a remainder of 57.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 512 from 569, we get 57.
Bring next digit (9) of the dividend behind the 57 and repeat the process: 579 / 64

Let's proceed to step 5:
579 divided by 64 is 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 189.0
The remainder is 3 after subtracting 576 from 579.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 64

Let's proceed to step 6:
64 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 1890.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
If we divide 300 by 64, we get 4 and a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 1890.4
The remainder is 44 after subtracting 256 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 8:
440 divided by 64 is 6 with a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 1890.46
Deduct 384 from 440 and we're left 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.

Let's proceed to step 9:
560 divided by 64 is 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 1890.468
If we subtract 512 from 560, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
If we divide 480 by 64, we get 7 and a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 1890.4687
Subtract 448 from 480 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
320 divided by 64 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1890.46875
If we take 320 away from 320, 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.

Going ahead to step 12:
When dividing 0 by 64, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1890.46875
Subtract 0 from 0 to 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.

Step 13:
When dividing 0 by 64, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1890.46875
The remainder is 0 after subtracting 0 from 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 result is 1890.46875 with a remainder of 0.0.
