42126238 divided by 64 
The aim is to understand the frequency of 64 in 42126238.

Step 1:
When dividing 4 by 64, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 64

On to step 2:
64 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 64

Going ahead to step 3:
When dividing 421 by 64, we get 6 with a remainder of 37.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 37 after subtracting 384 from 421.
Append the next digit (2) from the dividend to 37 and continue with: 372 / 64

Moving on to step 4:
64 can be fit into 372 5 times, resulting in a remainder of 52.
Write down 5 as next digit of the result. 
Result so far: 65.0
If we take 320 away from 372, we end up with 52.
Bring next digit (6) of the dividend behind the 52 and repeat the process: 526 / 64

Let's proceed to step 5:
64 goes into 526 8 times with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 658.0
Subtracting 512 from 526 leaves us with 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 64

On to step 6:
If we divide 142 by 64, we get 2 and a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 6582.0
The remainder is 14 after subtracting 128 from 142.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 64

Going ahead to step 7:
143 divided by 64 is 2 with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 65822.0
If we subtract 128 from 143, we get 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 64

On to step 8:
64 can be fit into 158 2 times, resulting in a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 658222.0
The remainder is 30 after subtracting 128 from 158.
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 9:
The number 64 fits into 300 4 times, leaving a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 658222.4
Subtract 256 from 300 to get 44.
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 10:
64 goes into 440 6 times with a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 658222.46
The remainder is 56 after subtracting 384 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 11:
560 divided by 64 is 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 658222.468
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.

Let's proceed to step 12:
64 can be fit into 480 7 times, resulting in a remainder of 32.
The next digit of our result is 7. 
Result so far: 658222.4687
If we take 448 away from 480, we end up 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.

Advancing to step 13:
If we divide 320 by 64, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 658222.46875
Subtract 320 from 320 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.

Advancing to step 14:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 658222.46875
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.

On to step 15:
0 divided by 64 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 658222.46875
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 final outcome is 658222.46875, with a leftover of 0.0.
