We divide 53899378 by 250
The aim is to understand the frequency of 250 in 53899378.

Moving on to step 1:
The number 250 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 250

Step 2:
250 can be fit into 53 0 times, resulting in a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Grab the next digit (8) from the dividend, add it to 53, then carry on: 538 / 250

Advancing to step 3:
250 can be fit into 538 2 times, resulting in a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 500 away from 538, we end up with 38.
Bring next digit (9) of the dividend behind the 38 and repeat the process: 389 / 250

Step 4:
When dividing 389 by 250, we get 1 with a remainder of 139.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 250 away from 389, we end up with 139.
Grab the next digit (9) from the dividend, add it to 139, then carry on: 1399 / 250

Step 5:
250 goes into 1399 5 times with a remainder of 149.
Put 5 as the next digit of the answer. 
Result so far: 215.0
Deduct 1250 from 1399 and we're left with 149.
Take the next digit (3) from the dividend and append it to 149, then repeat: 1493 / 250

Moving on to step 6:
250 can be fit into 1493 5 times, resulting in a remainder of 243.
Use 5 as the next digit of our solution. 
Result so far: 2155.0
Deduct 1250 from 1493 and we're left with 243.
Append the next digit (7) from the dividend to 243 and continue with: 2437 / 250

Advancing to step 7:
The number 250 fits into 2437 9 times, leaving a remainder of 187.
The number 9 becomes the next digit in our result. 
Result so far: 21559.0
Deduct 2250 from 2437 and we're left with 187.
Bring next digit (8) of the dividend behind the 187 and repeat the process: 1878 / 250

Advancing to step 8:
When dividing 1878 by 250, we get 7 with a remainder of 128.
The next digit of our result is 7. 
Result so far: 215597.0
Deduct 1750 from 1878 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 9:
When dividing 1280 by 250, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 215597.5
Subtracting 1250 from 1280 leaves us with 30.
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:
The number 250 fits into 300 1 times, leaving a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 215597.51
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.

Step 11:
250 goes into 500 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 215597.512
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.
Write down 0 as next digit of the result. 
Result so far: 215597.512
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.

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: 215597.512
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.

The final outcome is 215597.512, with a leftover of 0.0.
