We look at the division of 873902 by 67 
The aim is to understand the frequency of 67 in 873902.

On to step 1:
The number 67 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 67

Advancing to step 2:
If we divide 87 by 67, we get 1 and a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 20 after subtracting 67 from 87.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 67

Let's proceed to step 3:
203 divided by 67 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 201 away from 203, we end up with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 67

Let's proceed to step 4:
If we divide 29 by 67, we get 0 and a remainder of 29.
The next digit of our result is 0. 
Result so far: 130.0
Deduct 0 from 29 and we're left with 29.
Bring next digit (0) of the dividend behind the 29 and repeat the process: 290 / 67

Step 5:
67 can be fit into 290 4 times, resulting in a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 1304.0
Deduct 268 from 290 and we're left with 22.
Grab the next digit (2) from the dividend, add it to 22, then carry on: 222 / 67

Going ahead to step 6:
When dividing 222 by 67, we get 3 with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 13043.0
Deduct 201 from 222 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.

Let's proceed to step 7:
If we divide 210 by 67, we get 3 and a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 13043.3
Subtracting 201 from 210 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.

On to step 8:
When dividing 90 by 67, we get 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 13043.31
If we subtract 67 from 90, 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.

Going ahead to step 9:
The number 67 fits into 230 3 times, leaving a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 13043.313
If we subtract 201 from 230, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 10:
67 goes into 290 4 times with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 13043.3134
Deduct 268 from 290 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 11:
The number 67 fits into 220 3 times, leaving a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 13043.31343
Subtract 201 from 220 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 12:
190 divided by 67 is 2 with a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 13043.313432
Subtracting 134 from 190 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 13:
If we divide 560 by 67, we get 8 and a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 13043.3134328
Subtract 536 from 560 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
When dividing 240 by 67, we get 3 with a remainder of 39.
The next digit of our result is 3. 
Result so far: 13043.31343283
Subtract 201 from 240 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 13043.31343283, and the remainder is 3.9e-08.
