We look at the division of 39507477 by 212 
The aim is to understand the frequency of 212 in 39507477.

Going ahead to step 1:
When dividing 3 by 212, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 212

Going ahead to step 2:
When dividing 39 by 212, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 212

Let's proceed to step 3:
The number 212 fits into 395 1 times, leaving a remainder of 183.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 212 from 395 and we're left with 183.
Include the next digit (0) from the dividend after 183, then repeat: 1830 / 212

Going ahead to step 4:
When dividing 1830 by 212, we get 8 with a remainder of 134.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 1696 from 1830 leaves us with 134.
Include the next digit (7) from the dividend after 134, then repeat: 1347 / 212

Moving on to step 5:
If we divide 1347 by 212, we get 6 and a remainder of 75.
The number 6 becomes the next digit in our result. 
Result so far: 186.0
If we subtract 1272 from 1347, we get 75.
Include the next digit (4) from the dividend after 75, then repeat: 754 / 212

Moving on to step 6:
754 divided by 212 is 3 with a remainder of 118.
Use 3 as the next digit of our solution. 
Result so far: 1863.0
Deduct 636 from 754 and we're left with 118.
Take the next digit (7) from the dividend and append it to 118, then repeat: 1187 / 212

Advancing to step 7:
When dividing 1187 by 212, we get 5 with a remainder of 127.
Record the quotient 5 as the next digit in the result. 
Result so far: 18635.0
The remainder is 127 after subtracting 1060 from 1187.
Grab the next digit (7) from the dividend, add it to 127, then carry on: 1277 / 212

On to step 8:
The number 212 fits into 1277 6 times, leaving a remainder of 5.
The next digit of our result is 6. 
Result so far: 186356.0
Subtracting 1272 from 1277 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
212 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 186356.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
212 can be fit into 500 2 times, resulting in a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 186356.02
The remainder is 76 after subtracting 424 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 11:
The number 212 fits into 760 3 times, leaving a remainder of 124.
The number 3 becomes the next digit in our result. 
Result so far: 186356.023
Deduct 636 from 760 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 12:
The number 212 fits into 1240 5 times, leaving a remainder of 180.
The next digit of our result is 5. 
Result so far: 186356.0235
The remainder is 180 after subtracting 1060 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 13:
212 can be fit into 1800 8 times, resulting in a remainder of 104.
Put 8 as the next digit of the answer. 
Result so far: 186356.02358
If we take 1696 away from 1800, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 14:
1040 divided by 212 is 4 with a remainder of 192.
Put 4 as the next digit of the answer. 
Result so far: 186356.023584
If we subtract 848 from 1040, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 15:
212 goes into 1920 9 times with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 186356.0235849
Subtracting 1908 from 1920 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 16:
When dividing 120 by 212, we get 0 with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 186356.0235849
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Our division results in 186356.0235849 with a remaining 1.2e-07.
