Let's divide 66639815 by 152
The aim is to understand the frequency of 152 in 66639815.

Moving on to step 1:
When dividing 6 by 152, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 152

Going ahead to step 2:
If we divide 66 by 152, we get 0 and a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 152

Moving on to step 3:
When dividing 666 by 152, we get 4 with a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 608 from 666, we get 58.
Fetch the next digit (3) from the dividend, attach it to 58 and continue: 583 / 152

Going ahead to step 4:
152 can be fit into 583 3 times, resulting in a remainder of 127.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we take 456 away from 583, we end up with 127.
Bring next digit (9) of the dividend behind the 127 and repeat the process: 1279 / 152

Advancing to step 5:
When dividing 1279 by 152, we get 8 with a remainder of 63.
Write down 8 as next digit of the result. 
Result so far: 438.0
The remainder is 63 after subtracting 1216 from 1279.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 152

Going ahead to step 6:
152 can be fit into 638 4 times, resulting in a remainder of 30.
The next digit of our result is 4. 
Result so far: 4384.0
If we subtract 608 from 638, we get 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 152

Advancing to step 7:
When dividing 301 by 152, we get 1 with a remainder of 149.
The next digit of our result is 1. 
Result so far: 43841.0
Subtracting 152 from 301 leaves us with 149.
Grab the next digit (5) from the dividend, add it to 149, then carry on: 1495 / 152

Let's proceed to step 8:
If we divide 1495 by 152, we get 9 and a remainder of 127.
The next digit of our result is 9. 
Result so far: 438419.0
If we subtract 1368 from 1495, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 9:
The number 152 fits into 1270 8 times, leaving a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 438419.8
If we take 1216 away from 1270, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 10:
When dividing 540 by 152, we get 3 with a remainder of 84.
Record the quotient 3 as the next digit in the result. 
Result so far: 438419.83
Deduct 456 from 540 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 11:
840 divided by 152 is 5 with a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 438419.835
The remainder is 80 after subtracting 760 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
The number 152 fits into 800 5 times, leaving a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 438419.8355
The remainder is 40 after subtracting 760 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 438419.8355 with a remainder of 0.0004.
