We divide 68545870 by 252
The aim is to understand the frequency of 252 in 68545870.

Going ahead to step 1:
252 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 252

Step 2:
If we divide 68 by 252, we get 0 and a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Append the next digit (5) from the dividend to 68 and continue with: 685 / 252

Advancing to step 3:
If we divide 685 by 252, we get 2 and a remainder of 181.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 504 away from 685, we end up with 181.
Take the next digit (4) from the dividend and append it to 181, then repeat: 1814 / 252

Moving on to step 4:
If we divide 1814 by 252, we get 7 and a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Deduct 1764 from 1814 and we're left with 50.
Take the next digit (5) from the dividend and append it to 50, then repeat: 505 / 252

On to step 5:
252 can be fit into 505 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 272.0
If we take 504 away from 505, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 252

Step 6:
252 can be fit into 18 0 times, resulting in a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 2720.0
If we take 0 away from 18, we end up with 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 252

Moving on to step 7:
When dividing 187 by 252, we get 0 with a remainder of 187.
Record the quotient 0 as the next digit in the result. 
Result so far: 27200.0
Subtracting 0 from 187 leaves us with 187.
Fetch the next digit (0) from the dividend, attach it to 187 and continue: 1870 / 252

Let's proceed to step 8:
252 can be fit into 1870 7 times, resulting in a remainder of 106.
Put 7 as the next digit of the answer. 
Result so far: 272007.0
The remainder is 106 after subtracting 1764 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 9:
252 goes into 1060 4 times with a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 272007.4
If we subtract 1008 from 1060, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
The number 252 fits into 520 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 272007.42
Deduct 504 from 520 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
If we divide 160 by 252, we get 0 and a remainder of 160.
The next digit of our result is 0. 
Result so far: 272007.42
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 12:
If we divide 1600 by 252, we get 6 and a remainder of 88.
The number 6 becomes the next digit in our result. 
Result so far: 272007.4206
Deduct 1512 from 1600 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 13:
When dividing 880 by 252, we get 3 with a remainder of 124.
Use 3 as the next digit of our solution. 
Result so far: 272007.42063
Subtract 756 from 880 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 14:
252 goes into 1240 4 times with a remainder of 232.
The number 4 becomes the next digit in our result. 
Result so far: 272007.420634
Subtract 1008 from 1240 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 15:
If we divide 2320 by 252, we get 9 and a remainder of 52.
Put 9 as the next digit of the answer. 
Result so far: 272007.4206349
If we subtract 2268 from 2320, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 16:
The number 252 fits into 520 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 272007.42063492
If we subtract 504 from 520, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 272007.42063492 with a remaining 1.6e-08.
