76120644 divided by 250 
The aim is to understand the frequency of 250 in 76120644.

Advancing to step 1:
When dividing 7 by 250, we get 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 (6) from the dividend, attach it to 7 and continue: 76 / 250

Step 2:
If we divide 76 by 250, we get 0 and a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Bring next digit (1) of the dividend behind the 76 and repeat the process: 761 / 250

Let's proceed to step 3:
If we divide 761 by 250, we get 3 and a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 750 from 761 and we're left with 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 250

Going ahead to step 4:
250 goes into 112 0 times with a remainder of 112.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Subtract 0 from 112 to get 112.
Include the next digit (0) from the dividend after 112, then repeat: 1120 / 250

Step 5:
250 goes into 1120 4 times with a remainder of 120.
The number 4 becomes the next digit in our result. 
Result so far: 304.0
The remainder is 120 after subtracting 1000 from 1120.
Bring next digit (6) of the dividend behind the 120 and repeat the process: 1206 / 250

Step 6:
When dividing 1206 by 250, we get 4 with a remainder of 206.
The number 4 becomes the next digit in our result. 
Result so far: 3044.0
Subtracting 1000 from 1206 leaves us with 206.
Append the next digit (4) from the dividend to 206 and continue with: 2064 / 250

Advancing to step 7:
2064 divided by 250 is 8 with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 30448.0
If we subtract 2000 from 2064, we get 64.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 250

Step 8:
If we divide 644 by 250, we get 2 and a remainder of 144.
Put 2 as the next digit of the answer. 
Result so far: 304482.0
Subtract 500 from 644 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 9:
1440 divided by 250 is 5 with a remainder of 190.
Put 5 as the next digit of the answer. 
Result so far: 304482.5
Deduct 1250 from 1440 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 10:
1900 divided by 250 is 7 with a remainder of 150.
Record the quotient 7 as the next digit in the result. 
Result so far: 304482.57
The remainder is 150 after subtracting 1750 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 11:
250 goes into 1500 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 304482.576
If we take 1500 away from 1500, 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.

Advancing to step 12:
250 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 304482.576
Subtracting 0 from 0 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.

On to step 13:
250 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 304482.576
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.

The quotient of the division is 304482.576, and the remainder is 0.0.
