We divide 81996643 by 250
The aim is to understand the frequency of 250 in 81996643.

Going ahead to step 1:
250 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 250

Advancing to step 2:
The number 250 fits into 81 0 times, leaving a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Take the next digit (9) from the dividend and append it to 81, then repeat: 819 / 250

Let's proceed to step 3:
When dividing 819 by 250, we get 3 with a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 750 from 819 leaves us with 69.
Fetch the next digit (9) from the dividend, attach it to 69 and continue: 699 / 250

Let's proceed to step 4:
250 can be fit into 699 2 times, resulting in a remainder of 199.
Use 2 as the next digit of our solution. 
Result so far: 32.0
The remainder is 199 after subtracting 500 from 699.
Fetch the next digit (6) from the dividend, attach it to 199 and continue: 1996 / 250

Let's proceed to step 5:
If we divide 1996 by 250, we get 7 and a remainder of 246.
Use 7 as the next digit of our solution. 
Result so far: 327.0
Subtracting 1750 from 1996 leaves us with 246.
Take the next digit (6) from the dividend and append it to 246, then repeat: 2466 / 250

Moving on to step 6:
If we divide 2466 by 250, we get 9 and a remainder of 216.
Write down 9 as next digit of the result. 
Result so far: 3279.0
If we take 2250 away from 2466, we end up with 216.
Fetch the next digit (4) from the dividend, attach it to 216 and continue: 2164 / 250

Advancing to step 7:
2164 divided by 250 is 8 with a remainder of 164.
Put 8 as the next digit of the answer. 
Result so far: 32798.0
The remainder is 164 after subtracting 2000 from 2164.
Include the next digit (3) from the dividend after 164, then repeat: 1643 / 250

On to step 8:
250 can be fit into 1643 6 times, resulting in a remainder of 143.
Use 6 as the next digit of our solution. 
Result so far: 327986.0
The remainder is 143 after subtracting 1500 from 1643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Going ahead to step 9:
1430 divided by 250 is 5 with a remainder of 180.
Record the quotient 5 as the next digit in the result. 
Result so far: 327986.5
If we subtract 1250 from 1430, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 10:
250 goes into 1800 7 times with a remainder of 50.
Write down 7 as next digit of the result. 
Result so far: 327986.57
The remainder is 50 after subtracting 1750 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
250 goes into 500 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 327986.572
Subtract 500 from 500 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 12:
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: 327986.572
The remainder is 0 after subtracting 0 from 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.
Put 0 as the next digit of the answer. 
Result so far: 327986.572
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.

After the division, we end up with 327986.572 and a remainder of 0.0.
