We divide 31001211 by 209
The aim is to understand the frequency of 209 in 31001211.

On to step 1:
When dividing 3 by 209, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 209

Going ahead to step 2:
209 goes into 31 0 times with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 209

Let's proceed to step 3:
When dividing 310 by 209, we get 1 with a remainder of 101.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 209 from 310 to get 101.
Grab the next digit (0) from the dividend, add it to 101, then carry on: 1010 / 209

On to step 4:
When dividing 1010 by 209, we get 4 with a remainder of 174.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 836 from 1010 and we're left with 174.
Include the next digit (1) from the dividend after 174, then repeat: 1741 / 209

Let's proceed to step 5:
1741 divided by 209 is 8 with a remainder of 69.
Put 8 as the next digit of the answer. 
Result so far: 148.0
Subtracting 1672 from 1741 leaves us with 69.
Fetch the next digit (2) from the dividend, attach it to 69 and continue: 692 / 209

Step 6:
209 can be fit into 692 3 times, resulting in a remainder of 65.
Record the quotient 3 as the next digit in the result. 
Result so far: 1483.0
Deduct 627 from 692 and we're left with 65.
Fetch the next digit (1) from the dividend, attach it to 65 and continue: 651 / 209

Let's proceed to step 7:
651 divided by 209 is 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 14833.0
Deduct 627 from 651 and we're left with 24.
Include the next digit (1) from the dividend after 24, then repeat: 241 / 209

Going ahead to step 8:
The number 209 fits into 241 1 times, leaving a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 148331.0
If we take 209 away from 241, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
209 goes into 320 1 times with a remainder of 111.
Put 1 as the next digit of the answer. 
Result so far: 148331.1
If we subtract 209 from 320, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 10:
If we divide 1110 by 209, we get 5 and a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 148331.15
If we take 1045 away from 1110, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 11:
The number 209 fits into 650 3 times, leaving a remainder of 23.
The next digit of our result is 3. 
Result so far: 148331.153
If we subtract 627 from 650, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 12:
209 can be fit into 230 1 times, resulting in a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 148331.1531
Deduct 209 from 230 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 13:
209 goes into 210 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 148331.15311
Subtract 209 from 210 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 148331.15311 with a remaining 1e-06.
