37528839 ÷ 252 
The aim is to understand the frequency of 252 in 37528839.

Moving on to step 1:
252 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 252

Advancing to step 2:
252 can be fit into 37 0 times, resulting in a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Append the next digit (5) from the dividend to 37 and continue with: 375 / 252

Moving on to step 3:
The number 252 fits into 375 1 times, leaving a remainder of 123.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 252 from 375 and we're left with 123.
Bring next digit (2) of the dividend behind the 123 and repeat the process: 1232 / 252

Moving on to step 4:
The number 252 fits into 1232 4 times, leaving a remainder of 224.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 224 after subtracting 1008 from 1232.
Bring next digit (8) of the dividend behind the 224 and repeat the process: 2248 / 252

On to step 5:
When dividing 2248 by 252, we get 8 with a remainder of 232.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
Subtracting 2016 from 2248 leaves us with 232.
Bring next digit (8) of the dividend behind the 232 and repeat the process: 2328 / 252

Moving on to step 6:
If we divide 2328 by 252, we get 9 and a remainder of 60.
Put 9 as the next digit of the answer. 
Result so far: 1489.0
If we subtract 2268 from 2328, we get 60.
Fetch the next digit (3) from the dividend, attach it to 60 and continue: 603 / 252

Advancing to step 7:
If we divide 603 by 252, we get 2 and a remainder of 99.
Record the quotient 2 as the next digit in the result. 
Result so far: 14892.0
Deduct 504 from 603 and we're left with 99.
Append the next digit (9) from the dividend to 99 and continue with: 999 / 252

On to step 8:
252 goes into 999 3 times with a remainder of 243.
Use 3 as the next digit of our solution. 
Result so far: 148923.0
If we take 756 away from 999, we end up with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Step 9:
When dividing 2430 by 252, we get 9 with a remainder of 162.
Write down 9 as next digit of the result. 
Result so far: 148923.9
If we subtract 2268 from 2430, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 10:
When dividing 1620 by 252, we get 6 with a remainder of 108.
The next digit of our result is 6. 
Result so far: 148923.96
Subtracting 1512 from 1620 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 11:
1080 divided by 252 is 4 with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 148923.964
The remainder is 72 after subtracting 1008 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
The number 252 fits into 720 2 times, leaving a remainder of 216.
The next digit of our result is 2. 
Result so far: 148923.9642
If we subtract 504 from 720, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 13:
252 goes into 2160 8 times with a remainder of 144.
The number 8 becomes the next digit in our result. 
Result so far: 148923.96428
The remainder is 144 after subtracting 2016 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 14:
The number 252 fits into 1440 5 times, leaving a remainder of 180.
Write down 5 as next digit of the result. 
Result so far: 148923.964285
Deduct 1260 from 1440 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 15:
If we divide 1800 by 252, we get 7 and a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 148923.9642857
Deduct 1764 from 1800 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 16:
If we divide 360 by 252, we get 1 and a remainder of 108.
Use 1 as the next digit of our solution. 
Result so far: 148923.96428571
The remainder is 108 after subtracting 252 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

After the division, we end up with 148923.96428571 and a remainder of 1.08e-07.
