We're dividing 70421506 by 144 
The aim is to understand the frequency of 144 in 70421506.

Let's proceed to step 1:
7 divided by 144 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 144

Let's proceed to step 2:
The number 144 fits into 70 0 times, leaving a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Fetch the next digit (4) from the dividend, attach it to 70 and continue: 704 / 144

Step 3:
144 goes into 704 4 times with a remainder of 128.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 576 from 704 to get 128.
Append the next digit (2) from the dividend to 128 and continue with: 1282 / 144

Let's proceed to step 4:
The number 144 fits into 1282 8 times, leaving a remainder of 130.
Use 8 as the next digit of our solution. 
Result so far: 48.0
The remainder is 130 after subtracting 1152 from 1282.
Bring next digit (1) of the dividend behind the 130 and repeat the process: 1301 / 144

Advancing to step 5:
1301 divided by 144 is 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 489.0
Subtracting 1296 from 1301 leaves us with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 144

Going ahead to step 6:
144 can be fit into 55 0 times, resulting in a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 4890.0
Subtract 0 from 55 to get 55.
Take the next digit (0) from the dividend and append it to 55, then repeat: 550 / 144

Advancing to step 7:
When dividing 550 by 144, we get 3 with a remainder of 118.
The next digit of our result is 3. 
Result so far: 48903.0
If we subtract 432 from 550, we get 118.
Fetch the next digit (6) from the dividend, attach it to 118 and continue: 1186 / 144

Step 8:
144 goes into 1186 8 times with a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 489038.0
If we take 1152 away from 1186, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
340 divided by 144 is 2 with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 489038.2
Subtract 288 from 340 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
144 can be fit into 520 3 times, resulting in a remainder of 88.
Write down 3 as next digit of the result. 
Result so far: 489038.23
The remainder is 88 after subtracting 432 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 11:
If we divide 880 by 144, we get 6 and a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 489038.236
The remainder is 16 after subtracting 864 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
When dividing 160 by 144, we get 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 489038.2361
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
If we divide 160 by 144, we get 1 and a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 489038.23611
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 489038.23611, and the remainder is 1.6e-05.
