We divide 77797807 by 250
The aim is to understand the frequency of 250 in 77797807.

Moving on to step 1:
250 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 250

Going ahead to step 2:
250 can be fit into 77 0 times, resulting in a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Take the next digit (7) from the dividend and append it to 77, then repeat: 777 / 250

Step 3:
250 can be fit into 777 3 times, resulting in a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 27 after subtracting 750 from 777.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 250

On to step 4:
The number 250 fits into 279 1 times, leaving a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we subtract 250 from 279, we get 29.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 250

Moving on to step 5:
297 divided by 250 is 1 with a remainder of 47.
The next digit of our result is 1. 
Result so far: 311.0
Deduct 250 from 297 and we're left with 47.
Take the next digit (8) from the dividend and append it to 47, then repeat: 478 / 250

Step 6:
The number 250 fits into 478 1 times, leaving a remainder of 228.
Record the quotient 1 as the next digit in the result. 
Result so far: 3111.0
If we take 250 away from 478, we end up with 228.
Include the next digit (0) from the dividend after 228, then repeat: 2280 / 250

Advancing to step 7:
When dividing 2280 by 250, we get 9 with a remainder of 30.
Write down 9 as next digit of the result. 
Result so far: 31119.0
Deduct 2250 from 2280 and we're left with 30.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 250

Advancing to step 8:
If we divide 307 by 250, we get 1 and a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 311191.0
If we subtract 250 from 307, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 9:
250 can be fit into 570 2 times, resulting in a remainder of 70.
The next digit of our result is 2. 
Result so far: 311191.2
Deduct 500 from 570 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
700 divided by 250 is 2 with a remainder of 200.
Put 2 as the next digit of the answer. 
Result so far: 311191.22
The remainder is 200 after subtracting 500 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 311191.22, and the remainder is 0.2.
