Let's divide 83117691 by 207
The aim is to understand the frequency of 207 in 83117691.

On to step 1:
207 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 207

Let's proceed to step 2:
83 divided by 207 is 0 with a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Bring next digit (1) of the dividend behind the 83 and repeat the process: 831 / 207

Step 3:
The number 207 fits into 831 4 times, leaving a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 828 from 831 and we're left with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 207

Going ahead to step 4:
31 divided by 207 is 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
The remainder is 31 after subtracting 0 from 31.
Append the next digit (7) from the dividend to 31 and continue with: 317 / 207

Advancing to step 5:
207 goes into 317 1 times with a remainder of 110.
Record the quotient 1 as the next digit in the result. 
Result so far: 401.0
The remainder is 110 after subtracting 207 from 317.
Fetch the next digit (6) from the dividend, attach it to 110 and continue: 1106 / 207

Step 6:
The number 207 fits into 1106 5 times, leaving a remainder of 71.
Use 5 as the next digit of our solution. 
Result so far: 4015.0
If we take 1035 away from 1106, we end up with 71.
Append the next digit (9) from the dividend to 71 and continue with: 719 / 207

Let's proceed to step 7:
207 can be fit into 719 3 times, resulting in a remainder of 98.
Put 3 as the next digit of the answer. 
Result so far: 40153.0
Deduct 621 from 719 and we're left with 98.
Append the next digit (1) from the dividend to 98 and continue with: 981 / 207

On to step 8:
If we divide 981 by 207, we get 4 and a remainder of 153.
Use 4 as the next digit of our solution. 
Result so far: 401534.0
Deduct 828 from 981 and we're left 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.

Advancing to step 9:
1530 divided by 207 is 7 with a remainder of 81.
The number 7 becomes the next digit in our result. 
Result so far: 401534.7
Subtract 1449 from 1530 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 10:
If we divide 810 by 207, we get 3 and a remainder of 189.
Record the quotient 3 as the next digit in the result. 
Result so far: 401534.73
Subtracting 621 from 810 leaves us with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Moving on to step 11:
207 goes into 1890 9 times with a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 401534.739
The remainder is 27 after subtracting 1863 from 1890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 12:
The number 207 fits into 270 1 times, leaving a remainder of 63.
Use 1 as the next digit of our solution. 
Result so far: 401534.7391
Subtracting 207 from 270 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 13:
When dividing 630 by 207, we get 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 401534.73913
Subtracting 621 from 630 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 14:
When dividing 90 by 207, we get 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 401534.73913
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 15:
900 divided by 207 is 4 with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 401534.7391304
Subtract 828 from 900 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 16:
207 can be fit into 720 3 times, resulting in a remainder of 99.
The number 3 becomes the next digit in our result. 
Result so far: 401534.73913043
If we subtract 621 from 720, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

After the division, we end up with 401534.73913043 and a remainder of 9.9e-08.
