We look at the division of 843655 by 67 
The aim is to understand the frequency of 67 in 843655.

Advancing to step 1:
If we divide 8 by 67, we get 0 and 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.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 67

Advancing to step 2:
If we divide 84 by 67, we get 1 and a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 67 from 84 to get 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 67

Let's proceed to step 3:
67 can be fit into 173 2 times, resulting in a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 39 after subtracting 134 from 173.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 67

Going ahead to step 4:
396 divided by 67 is 5 with a remainder of 61.
Put 5 as the next digit of the answer. 
Result so far: 125.0
The remainder is 61 after subtracting 335 from 396.
Include the next digit (5) from the dividend after 61, then repeat: 615 / 67

On to step 5:
If we divide 615 by 67, we get 9 and a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 1259.0
Deduct 603 from 615 and we're left with 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 67

Moving on to step 6:
The number 67 fits into 125 1 times, leaving a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 12591.0
If we subtract 67 from 125, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 7:
If we divide 580 by 67, we get 8 and a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 12591.8
Subtract 536 from 580 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 8:
The number 67 fits into 440 6 times, leaving a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 12591.86
Subtracting 402 from 440 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
67 goes into 380 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 12591.865
Subtract 335 from 380 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 10:
The number 67 fits into 450 6 times, leaving a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 12591.8656
If we subtract 402 from 450, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
The number 67 fits into 480 7 times, leaving a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 12591.86567
Deduct 469 from 480 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 12:
When dividing 110 by 67, we get 1 with a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 12591.865671
The remainder is 43 after subtracting 67 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 13:
67 goes into 430 6 times with a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 12591.8656716
Deduct 402 from 430 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 14:
280 divided by 67 is 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 12591.86567164
Deduct 268 from 280 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 12591.86567164 with a remaining 1.2e-08.
