We divide 21265144 by 253
The aim is to understand the frequency of 253 in 21265144.

Let's proceed to step 1:
253 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 253

Step 2:
The number 253 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 253

Let's proceed to step 3:
253 can be fit into 212 0 times, resulting in a remainder of 212.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 212, we end up with 212.
Grab the next digit (6) from the dividend, add it to 212, then carry on: 2126 / 253

Advancing to step 4:
2126 divided by 253 is 8 with a remainder of 102.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 102 after subtracting 2024 from 2126.
Include the next digit (5) from the dividend after 102, then repeat: 1025 / 253

Advancing to step 5:
253 goes into 1025 4 times with a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
If we take 1012 away from 1025, we end up with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 253

Step 6:
If we divide 131 by 253, we get 0 and a remainder of 131.
Put 0 as the next digit of the answer. 
Result so far: 840.0
Subtracting 0 from 131 leaves us with 131.
Bring next digit (4) of the dividend behind the 131 and repeat the process: 1314 / 253

Step 7:
253 goes into 1314 5 times with a remainder of 49.
Record the quotient 5 as the next digit in the result. 
Result so far: 8405.0
If we take 1265 away from 1314, we end up with 49.
Bring next digit (4) of the dividend behind the 49 and repeat the process: 494 / 253

Let's proceed to step 8:
The number 253 fits into 494 1 times, leaving a remainder of 241.
The next digit of our result is 1. 
Result so far: 84051.0
Subtracting 253 from 494 leaves us with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Moving on to step 9:
253 can be fit into 2410 9 times, resulting in a remainder of 133.
The next digit of our result is 9. 
Result so far: 84051.9
Subtracting 2277 from 2410 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 10:
253 can be fit into 1330 5 times, resulting in a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 84051.95
If we take 1265 away from 1330, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 11:
The number 253 fits into 650 2 times, leaving a remainder of 144.
Write down 2 as next digit of the result. 
Result so far: 84051.952
If we take 506 away from 650, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 12:
253 can be fit into 1440 5 times, resulting in a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 84051.9525
Subtracting 1265 from 1440 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 13:
253 can be fit into 1750 6 times, resulting in a remainder of 232.
The next digit of our result is 6. 
Result so far: 84051.95256
The remainder is 232 after subtracting 1518 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 14:
253 goes into 2320 9 times with a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 84051.952569
If we subtract 2277 from 2320, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 15:
253 goes into 430 1 times with a remainder of 177.
The next digit of our result is 1. 
Result so far: 84051.9525691
If we take 253 away from 430, we end up with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Let's proceed to step 16:
If we divide 1770 by 253, we get 6 and a remainder of 252.
The next digit of our result is 6. 
Result so far: 84051.95256916
Subtract 1518 from 1770 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

The final outcome is 84051.95256916, with a leftover of 2.52e-07.
