We look at the division of 142790 by 64 
The aim is to understand the frequency of 64 in 142790.

Let's proceed to step 1:
When dividing 1 by 64, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 64

On to step 2:
If we divide 14 by 64, we get 0 and a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 64

Going ahead to step 3:
When dividing 142 by 64, we get 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 128 away from 142, we end up with 14.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 64

Moving on to step 4:
147 divided by 64 is 2 with a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we subtract 128 from 147, we get 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 64

Let's proceed to step 5:
64 can be fit into 199 3 times, resulting in a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 223.0
Subtract 192 from 199 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 64

On to step 6:
When dividing 70 by 64, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 2231.0
Subtract 64 from 70 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
If we divide 60 by 64, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 2231.0
If we take 0 away from 60, we end up 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.

Advancing to step 8:
600 divided by 64 is 9 with a remainder of 24.
The next digit of our result is 9. 
Result so far: 2231.09
The remainder is 24 after subtracting 576 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
When dividing 240 by 64, we get 3 with a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 2231.093
If we subtract 192 from 240, 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.

Advancing to step 10:
When dividing 480 by 64, we get 7 with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 2231.0937
Deduct 448 from 480 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
64 can be fit into 320 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2231.09375
Subtracting 320 from 320 leaves us 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.

Moving on to step 12:
64 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2231.09375
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.

On to step 13:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2231.09375
If we subtract 0 from 0, 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.

The quotient of the division is 2231.09375, and the remainder is 0.0.
