We look at the division of 858987 by 67 
The aim is to understand the frequency of 67 in 858987.

Going ahead to step 1:
67 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 67

On to step 2:
67 can be fit into 85 1 times, resulting in a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 67 from 85 to get 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 67

Let's proceed to step 3:
67 can be fit into 188 2 times, resulting in a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 54 after subtracting 134 from 188.
Bring next digit (9) of the dividend behind the 54 and repeat the process: 549 / 67

Let's proceed to step 4:
When dividing 549 by 67, we get 8 with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 128.0
If we subtract 536 from 549, we get 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 67

On to step 5:
When dividing 138 by 67, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 1282.0
The remainder is 4 after subtracting 134 from 138.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 67

Step 6:
If we divide 47 by 67, we get 0 and a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 12820.0
The remainder is 47 after subtracting 0 from 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 7:
When dividing 470 by 67, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 12820.7
Deduct 469 from 470 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
The number 67 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 12820.7
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
If we divide 100 by 67, we get 1 and a remainder of 33.
The next digit of our result is 1. 
Result so far: 12820.701
Deduct 67 from 100 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 10:
330 divided by 67 is 4 with a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 12820.7014
If we subtract 268 from 330, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 11:
The number 67 fits into 620 9 times, leaving a remainder of 17.
The next digit of our result is 9. 
Result so far: 12820.70149
Subtract 603 from 620 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 12:
When dividing 170 by 67, we get 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 12820.701492
Deduct 134 from 170 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 13:
67 can be fit into 360 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 12820.7014925
Subtracting 335 from 360 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 14:
250 divided by 67 is 3 with a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 12820.70149253
The remainder is 49 after subtracting 201 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final outcome is 12820.70149253, with a leftover of 4.9e-08.
