We look at the division of 72371136 by 211 
The aim is to understand the frequency of 211 in 72371136.

Step 1:
211 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 211

Advancing to step 2:
211 goes into 72 0 times with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Include the next digit (3) from the dividend after 72, then repeat: 723 / 211

Step 3:
When dividing 723 by 211, we get 3 with a remainder of 90.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 90 after subtracting 633 from 723.
Take the next digit (7) from the dividend and append it to 90, then repeat: 907 / 211

Advancing to step 4:
If we divide 907 by 211, we get 4 and a remainder of 63.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
If we take 844 away from 907, we end up with 63.
Fetch the next digit (1) from the dividend, attach it to 63 and continue: 631 / 211

Let's proceed to step 5:
If we divide 631 by 211, we get 2 and a remainder of 209.
Put 2 as the next digit of the answer. 
Result so far: 342.0
Subtract 422 from 631 to get 209.
Include the next digit (1) from the dividend after 209, then repeat: 2091 / 211

Going ahead to step 6:
If we divide 2091 by 211, we get 9 and a remainder of 192.
Use 9 as the next digit of our solution. 
Result so far: 3429.0
If we take 1899 away from 2091, we end up with 192.
Bring next digit (3) of the dividend behind the 192 and repeat the process: 1923 / 211

On to step 7:
211 goes into 1923 9 times with a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 34299.0
If we take 1899 away from 1923, we end up with 24.
Include the next digit (6) from the dividend after 24, then repeat: 246 / 211

Advancing to step 8:
If we divide 246 by 211, we get 1 and a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 342991.0
The remainder is 35 after subtracting 211 from 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
If we divide 350 by 211, we get 1 and a remainder of 139.
The next digit of our result is 1. 
Result so far: 342991.1
Deduct 211 from 350 and we're left with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Going ahead to step 10:
211 can be fit into 1390 6 times, resulting in a remainder of 124.
The number 6 becomes the next digit in our result. 
Result so far: 342991.16
If we take 1266 away from 1390, we end up 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.

Going ahead to step 11:
If we divide 1240 by 211, we get 5 and a remainder of 185.
Write down 5 as next digit of the result. 
Result so far: 342991.165
The remainder is 185 after subtracting 1055 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 12:
The number 211 fits into 1850 8 times, leaving a remainder of 162.
Use 8 as the next digit of our solution. 
Result so far: 342991.1658
Subtracting 1688 from 1850 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Let's proceed to step 13:
1620 divided by 211 is 7 with a remainder of 143.
Use 7 as the next digit of our solution. 
Result so far: 342991.16587
Deduct 1477 from 1620 and we're left with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Advancing to step 14:
211 goes into 1430 6 times with a remainder of 164.
Use 6 as the next digit of our solution. 
Result so far: 342991.165876
Deduct 1266 from 1430 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 15:
1640 divided by 211 is 7 with a remainder of 163.
Put 7 as the next digit of the answer. 
Result so far: 342991.1658767
Deduct 1477 from 1640 and we're left with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

On to step 16:
When dividing 1630 by 211, we get 7 with a remainder of 153.
Record the quotient 7 as the next digit in the result. 
Result so far: 342991.16587677
Subtracting 1477 from 1630 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

The final result is 342991.16587677 with a remainder of 1.53e-07.
