We divide 66879854 by 150
The aim is to understand the frequency of 150 in 66879854.

Let's proceed to step 1:
150 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 150

On to step 2:
150 can be fit into 66 0 times, resulting in a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 150

Step 3:
When dividing 668 by 150, we get 4 with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 600 from 668 to get 68.
Take the next digit (7) from the dividend and append it to 68, then repeat: 687 / 150

Let's proceed to step 4:
150 can be fit into 687 4 times, resulting in a remainder of 87.
Write down 4 as next digit of the result. 
Result so far: 44.0
Subtract 600 from 687 to get 87.
Grab the next digit (9) from the dividend, add it to 87, then carry on: 879 / 150

On to step 5:
150 goes into 879 5 times with a remainder of 129.
Write down 5 as next digit of the result. 
Result so far: 445.0
If we subtract 750 from 879, we get 129.
Include the next digit (8) from the dividend after 129, then repeat: 1298 / 150

Advancing to step 6:
When dividing 1298 by 150, we get 8 with a remainder of 98.
Write down 8 as next digit of the result. 
Result so far: 4458.0
If we subtract 1200 from 1298, we get 98.
Take the next digit (5) from the dividend and append it to 98, then repeat: 985 / 150

Going ahead to step 7:
985 divided by 150 is 6 with a remainder of 85.
The next digit of our result is 6. 
Result so far: 44586.0
If we take 900 away from 985, we end up with 85.
Grab the next digit (4) from the dividend, add it to 85, then carry on: 854 / 150

Moving on to step 8:
When dividing 854 by 150, we get 5 with a remainder of 104.
Write down 5 as next digit of the result. 
Result so far: 445865.0
If we subtract 750 from 854, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 9:
150 can be fit into 1040 6 times, resulting in a remainder of 140.
Use 6 as the next digit of our solution. 
Result so far: 445865.6
If we take 900 away from 1040, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 10:
150 can be fit into 1400 9 times, resulting in a remainder of 50.
The next digit of our result is 9. 
Result so far: 445865.69
If we take 1350 away from 1400, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
The number 150 fits into 500 3 times, leaving a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 445865.693
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 12:
If we divide 500 by 150, we get 3 and a remainder of 50.
Use 3 as the next digit of our solution. 
Result so far: 445865.6933
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 445865.6933 and a remainder of 0.0005.
