We divide 21205833 by 248
The aim is to understand the frequency of 248 in 21205833.

Step 1:
When dividing 2 by 248, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 248

Advancing to step 2:
248 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 248

On to step 3:
212 divided by 248 is 0 with a remainder of 212.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 212, we end up with 212.
Grab the next digit (0) from the dividend, add it to 212, then carry on: 2120 / 248

Let's proceed to step 4:
The number 248 fits into 2120 8 times, leaving a remainder of 136.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 1984 from 2120, we get 136.
Append the next digit (5) from the dividend to 136 and continue with: 1365 / 248

Let's proceed to step 5:
If we divide 1365 by 248, we get 5 and a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 85.0
If we subtract 1240 from 1365, we get 125.
Bring next digit (8) of the dividend behind the 125 and repeat the process: 1258 / 248

Moving on to step 6:
1258 divided by 248 is 5 with a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 855.0
If we take 1240 away from 1258, we end up with 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 248

Advancing to step 7:
183 divided by 248 is 0 with a remainder of 183.
Put 0 as the next digit of the answer. 
Result so far: 8550.0
Subtracting 0 from 183 leaves us with 183.
Take the next digit (3) from the dividend and append it to 183, then repeat: 1833 / 248

Let's proceed to step 8:
The number 248 fits into 1833 7 times, leaving a remainder of 97.
Put 7 as the next digit of the answer. 
Result so far: 85507.0
Deduct 1736 from 1833 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Going ahead to step 9:
When dividing 970 by 248, we get 3 with a remainder of 226.
Record the quotient 3 as the next digit in the result. 
Result so far: 85507.3
Subtracting 744 from 970 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 10:
When dividing 2260 by 248, we get 9 with a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 85507.39
Subtract 2232 from 2260 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
When dividing 280 by 248, we get 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 85507.391
If we take 248 away from 280, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
320 divided by 248 is 1 with a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 85507.3911
If we take 248 away from 320, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 85507.3911, with a leftover of 0.00072.
