We're dividing 40252389 by 212 
The aim is to understand the frequency of 212 in 40252389.

Let's proceed to step 1:
212 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 212

Step 2:
40 divided by 212 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Take the next digit (2) from the dividend and append it to 40, then repeat: 402 / 212

Step 3:
If we divide 402 by 212, we get 1 and a remainder of 190.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 212 from 402 to get 190.
Take the next digit (5) from the dividend and append it to 190, then repeat: 1905 / 212

Let's proceed to step 4:
The number 212 fits into 1905 8 times, leaving a remainder of 209.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 1696 from 1905, we get 209.
Bring next digit (2) of the dividend behind the 209 and repeat the process: 2092 / 212

Step 5:
2092 divided by 212 is 9 with a remainder of 184.
The next digit of our result is 9. 
Result so far: 189.0
If we take 1908 away from 2092, we end up with 184.
Grab the next digit (3) from the dividend, add it to 184, then carry on: 1843 / 212

Let's proceed to step 6:
1843 divided by 212 is 8 with a remainder of 147.
The number 8 becomes the next digit in our result. 
Result so far: 1898.0
If we take 1696 away from 1843, we end up with 147.
Grab the next digit (8) from the dividend, add it to 147, then carry on: 1478 / 212

On to step 7:
212 can be fit into 1478 6 times, resulting in a remainder of 206.
Write down 6 as next digit of the result. 
Result so far: 18986.0
Subtracting 1272 from 1478 leaves us with 206.
Bring next digit (9) of the dividend behind the 206 and repeat the process: 2069 / 212

Going ahead to step 8:
The number 212 fits into 2069 9 times, leaving a remainder of 161.
The next digit of our result is 9. 
Result so far: 189869.0
Deduct 1908 from 2069 and we're left with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

On to step 9:
When dividing 1610 by 212, we get 7 with a remainder of 126.
Write down 7 as next digit of the result. 
Result so far: 189869.7
Subtracting 1484 from 1610 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 10:
When dividing 1260 by 212, we get 5 with a remainder of 200.
Write down 5 as next digit of the result. 
Result so far: 189869.75
If we take 1060 away from 1260, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 11:
The number 212 fits into 2000 9 times, leaving a remainder of 92.
Record the quotient 9 as the next digit in the result. 
Result so far: 189869.759
The remainder is 92 after subtracting 1908 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 12:
212 goes into 920 4 times with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 189869.7594
The remainder is 72 after subtracting 848 from 920.
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 13:
720 divided by 212 is 3 with a remainder of 84.
Put 3 as the next digit of the answer. 
Result so far: 189869.75943
Subtracting 636 from 720 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 14:
The number 212 fits into 840 3 times, leaving a remainder of 204.
The next digit of our result is 3. 
Result so far: 189869.759433
Subtracting 636 from 840 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

The quotient of the division is 189869.759433, and the remainder is 2.04e-05.
