We're dividing 80140195 by 252 
The aim is to understand the frequency of 252 in 80140195.

On to step 1:
The number 252 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 252

Step 2:
The number 252 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Bring next digit (1) of the dividend behind the 80 and repeat the process: 801 / 252

Moving on to step 3:
When dividing 801 by 252, we get 3 with a remainder of 45.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 756 from 801 leaves us with 45.
Bring next digit (4) of the dividend behind the 45 and repeat the process: 454 / 252

Step 4:
If we divide 454 by 252, we get 1 and a remainder of 202.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we take 252 away from 454, we end up with 202.
Fetch the next digit (0) from the dividend, attach it to 202 and continue: 2020 / 252

On to step 5:
2020 divided by 252 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 318.0
If we subtract 2016 from 2020, we get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 252

Going ahead to step 6:
252 goes into 41 0 times with a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 3180.0
Subtracting 0 from 41 leaves us with 41.
Append the next digit (9) from the dividend to 41 and continue with: 419 / 252

Going ahead to step 7:
252 goes into 419 1 times with a remainder of 167.
The next digit of our result is 1. 
Result so far: 31801.0
If we subtract 252 from 419, we get 167.
Bring next digit (5) of the dividend behind the 167 and repeat the process: 1675 / 252

Advancing to step 8:
1675 divided by 252 is 6 with a remainder of 163.
Record the quotient 6 as the next digit in the result. 
Result so far: 318016.0
Subtract 1512 from 1675 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Advancing to step 9:
When dividing 1630 by 252, we get 6 with a remainder of 118.
Write down 6 as next digit of the result. 
Result so far: 318016.6
If we take 1512 away from 1630, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 10:
When dividing 1180 by 252, we get 4 with a remainder of 172.
Put 4 as the next digit of the answer. 
Result so far: 318016.64
Subtracting 1008 from 1180 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 11:
252 goes into 1720 6 times with a remainder of 208.
Use 6 as the next digit of our solution. 
Result so far: 318016.646
The remainder is 208 after subtracting 1512 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 12:
2080 divided by 252 is 8 with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 318016.6468
Subtracting 2016 from 2080 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 13:
The number 252 fits into 640 2 times, leaving a remainder of 136.
The next digit of our result is 2. 
Result so far: 318016.64682
Subtract 504 from 640 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 14:
1360 divided by 252 is 5 with a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 318016.646825
If we subtract 1260 from 1360, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 15:
1000 divided by 252 is 3 with a remainder of 244.
Record the quotient 3 as the next digit in the result. 
Result so far: 318016.6468253
Deduct 756 from 1000 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 16:
2440 divided by 252 is 9 with a remainder of 172.
The number 9 becomes the next digit in our result. 
Result so far: 318016.64682539
The remainder is 172 after subtracting 2268 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The quotient of the division is 318016.64682539, and the remainder is 1.72e-07.
