48126878 ÷ 212 
The aim is to understand the frequency of 212 in 48126878.

On to step 1:
The number 212 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 212

Moving on to step 2:
212 can be fit into 48 0 times, resulting in a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 48 after subtracting 0 from 48.
Append the next digit (1) from the dividend to 48 and continue with: 481 / 212

Going ahead to step 3:
212 can be fit into 481 2 times, resulting in a remainder of 57.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 424 from 481 to get 57.
Include the next digit (2) from the dividend after 57, then repeat: 572 / 212

Let's proceed to step 4:
212 can be fit into 572 2 times, resulting in a remainder of 148.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtract 424 from 572 to get 148.
Take the next digit (6) from the dividend and append it to 148, then repeat: 1486 / 212

On to step 5:
If we divide 1486 by 212, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 227.0
Subtract 1484 from 1486 to get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 212

Let's proceed to step 6:
28 divided by 212 is 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 2270.0
Subtracting 0 from 28 leaves us with 28.
Take the next digit (7) from the dividend and append it to 28, then repeat: 287 / 212

Moving on to step 7:
287 divided by 212 is 1 with a remainder of 75.
Write down 1 as next digit of the result. 
Result so far: 22701.0
Subtract 212 from 287 to get 75.
Fetch the next digit (8) from the dividend, attach it to 75 and continue: 758 / 212

Going ahead to step 8:
If we divide 758 by 212, we get 3 and a remainder of 122.
Put 3 as the next digit of the answer. 
Result so far: 227013.0
Deduct 636 from 758 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 9:
When dividing 1220 by 212, we get 5 with a remainder of 160.
Write down 5 as next digit of the result. 
Result so far: 227013.5
The remainder is 160 after subtracting 1060 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 10:
212 can be fit into 1600 7 times, resulting in a remainder of 116.
Write down 7 as next digit of the result. 
Result so far: 227013.57
Deduct 1484 from 1600 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 11:
If we divide 1160 by 212, we get 5 and a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 227013.575
Subtracting 1060 from 1160 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 12:
212 can be fit into 1000 4 times, resulting in a remainder of 152.
Record the quotient 4 as the next digit in the result. 
Result so far: 227013.5754
Subtract 848 from 1000 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 13:
212 can be fit into 1520 7 times, resulting in a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 227013.57547
Subtracting 1484 from 1520 leaves us 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.

Going ahead to step 14:
212 can be fit into 360 1 times, resulting in a remainder of 148.
Put 1 as the next digit of the answer. 
Result so far: 227013.575471
Deduct 212 from 360 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 15:
When dividing 1480 by 212, we get 6 with a remainder of 208.
Write down 6 as next digit of the result. 
Result so far: 227013.5754716
Subtracting 1272 from 1480 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 16:
2080 divided by 212 is 9 with a remainder of 172.
The next digit of our result is 9. 
Result so far: 227013.57547169
Deduct 1908 from 2080 and we're left 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.

After the division, we end up with 227013.57547169 and a remainder of 1.72e-07.
