We look at the division of 1660548 by 207 
The aim is to understand the frequency of 207 in 1660548.

Step 1:
207 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 207

Step 2:
207 can be fit into 16 0 times, resulting in a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 207

On to step 3:
166 divided by 207 is 0 with a remainder of 166.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 166, we end up with 166.
Append the next digit (0) from the dividend to 166 and continue with: 1660 / 207

Step 4:
1660 divided by 207 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 4 after subtracting 1656 from 1660.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 207

Step 5:
When dividing 45 by 207, we get 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Subtracting 0 from 45 leaves us with 45.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 207

On to step 6:
207 goes into 454 2 times with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 802.0
Subtracting 414 from 454 leaves us with 40.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 207

Advancing to step 7:
When dividing 408 by 207, we get 1 with a remainder of 201.
Put 1 as the next digit of the answer. 
Result so far: 8021.0
Subtract 207 from 408 to get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Let's proceed to step 8:
207 goes into 2010 9 times with a remainder of 147.
Write down 9 as next digit of the result. 
Result so far: 8021.9
Deduct 1863 from 2010 and we're left with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Going ahead to step 9:
207 goes into 1470 7 times with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 8021.97
Deduct 1449 from 1470 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 10:
The number 207 fits into 210 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 8021.971
Subtract 207 from 210 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
30 divided by 207 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 8021.971
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
The number 207 fits into 300 1 times, leaving a remainder of 93.
The number 1 becomes the next digit in our result. 
Result so far: 8021.97101
Subtract 207 from 300 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Let's proceed to step 13:
207 can be fit into 930 4 times, resulting in a remainder of 102.
Write down 4 as next digit of the result. 
Result so far: 8021.971014
The remainder is 102 after subtracting 828 from 930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 14:
207 goes into 1020 4 times with a remainder of 192.
Write down 4 as next digit of the result. 
Result so far: 8021.9710144
Subtract 828 from 1020 to 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.

The quotient of the division is 8021.9710144, and the remainder is 1.92e-06.
