66356153 divided by 250 
The aim is to understand the frequency of 250 in 66356153.

Going ahead to step 1:
6 divided by 250 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 250

Let's proceed to step 2:
250 can be fit into 66 0 times, resulting in a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (3) from the dividend, add it to 66, then carry on: 663 / 250

Let's proceed to step 3:
663 divided by 250 is 2 with a remainder of 163.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 500 away from 663, we end up with 163.
Take the next digit (5) from the dividend and append it to 163, then repeat: 1635 / 250

On to step 4:
If we divide 1635 by 250, we get 6 and a remainder of 135.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we subtract 1500 from 1635, we get 135.
Fetch the next digit (6) from the dividend, attach it to 135 and continue: 1356 / 250

Let's proceed to step 5:
250 goes into 1356 5 times with a remainder of 106.
The number 5 becomes the next digit in our result. 
Result so far: 265.0
Deduct 1250 from 1356 and we're left with 106.
Bring next digit (1) of the dividend behind the 106 and repeat the process: 1061 / 250

Advancing to step 6:
1061 divided by 250 is 4 with a remainder of 61.
The number 4 becomes the next digit in our result. 
Result so far: 2654.0
Subtract 1000 from 1061 to get 61.
Append the next digit (5) from the dividend to 61 and continue with: 615 / 250

Moving on to step 7:
If we divide 615 by 250, we get 2 and a remainder of 115.
The next digit of our result is 2. 
Result so far: 26542.0
If we subtract 500 from 615, we get 115.
Fetch the next digit (3) from the dividend, attach it to 115 and continue: 1153 / 250

Going ahead to step 8:
250 goes into 1153 4 times with a remainder of 153.
The next digit of our result is 4. 
Result so far: 265424.0
If we take 1000 away from 1153, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 9:
The number 250 fits into 1530 6 times, leaving a remainder of 30.
The next digit of our result is 6. 
Result so far: 265424.6
The remainder is 30 after subtracting 1500 from 1530.
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 10:
300 divided by 250 is 1 with a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 265424.61
Subtract 250 from 300 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
250 goes into 500 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 265424.612
Subtracting 500 from 500 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.

Going ahead to step 12:
When dividing 0 by 250, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 265424.612
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.

Going ahead to step 13:
If we divide 0 by 250, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 265424.612
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.

After the division, we end up with 265424.612 and a remainder of 0.0.
