Let's divide 77601958 by 250
The aim is to understand the frequency of 250 in 77601958.

Step 1:
When dividing 7 by 250, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 250

Moving on to step 2:
250 can be fit into 77 0 times, resulting in a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Grab the next digit (6) from the dividend, add it to 77, then carry on: 776 / 250

Advancing to step 3:
When dividing 776 by 250, we get 3 with a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 750 from 776 to get 26.
Grab the next digit (0) from the dividend, add it to 26, then carry on: 260 / 250

Step 4:
If we divide 260 by 250, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 31.0
If we subtract 250 from 260, we get 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 250

Advancing to step 5:
The number 250 fits into 101 0 times, leaving a remainder of 101.
Put 0 as the next digit of the answer. 
Result so far: 310.0
Deduct 0 from 101 and we're left with 101.
Grab the next digit (9) from the dividend, add it to 101, then carry on: 1019 / 250

Going ahead to step 6:
250 can be fit into 1019 4 times, resulting in a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 3104.0
Subtracting 1000 from 1019 leaves us with 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 250

Advancing to step 7:
If we divide 195 by 250, we get 0 and a remainder of 195.
Put 0 as the next digit of the answer. 
Result so far: 31040.0
The remainder is 195 after subtracting 0 from 195.
Take the next digit (8) from the dividend and append it to 195, then repeat: 1958 / 250

Step 8:
250 goes into 1958 7 times with a remainder of 208.
Write down 7 as next digit of the result. 
Result so far: 310407.0
If we take 1750 away from 1958, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 9:
2080 divided by 250 is 8 with a remainder of 80.
The next digit of our result is 8. 
Result so far: 310407.8
The remainder is 80 after subtracting 2000 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
250 goes into 800 3 times with a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 310407.83
Subtracting 750 from 800 leaves us 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 11:
250 can be fit into 500 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 310407.832
If we take 500 away from 500, 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.

Let's proceed to step 12:
250 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 310407.832
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:
When dividing 0 by 250, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 310407.832
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.

The final result is 310407.832 with a remainder of 0.0.
