We look at the division of 154681 by 67 
The aim is to understand the frequency of 67 in 154681.

On to step 1:
1 divided by 67 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 67

On to step 2:
If we divide 15 by 67, we get 0 and a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 67

Step 3:
67 goes into 154 2 times with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 134 from 154, we get 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 67

Advancing to step 4:
67 can be fit into 206 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we take 201 away from 206, we end up with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 67

Advancing to step 5:
If we divide 58 by 67, we get 0 and a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 230.0
Subtract 0 from 58 to get 58.
Grab the next digit (1) from the dividend, add it to 58, then carry on: 581 / 67

Step 6:
If we divide 581 by 67, we get 8 and a remainder of 45.
Put 8 as the next digit of the answer. 
Result so far: 2308.0
Subtracting 536 from 581 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
67 goes into 450 6 times with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 2308.6
Deduct 402 from 450 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
67 can be fit into 480 7 times, resulting in a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 2308.67
The remainder is 11 after subtracting 469 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
110 divided by 67 is 1 with a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 2308.671
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 10:
430 divided by 67 is 6 with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 2308.6716
Subtract 402 from 430 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
The number 67 fits into 280 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 2308.67164
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.

Step 12:
67 can be fit into 120 1 times, resulting in a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 2308.671641
The remainder is 53 after subtracting 67 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 13:
67 can be fit into 530 7 times, resulting in a remainder of 61.
The number 7 becomes the next digit in our result. 
Result so far: 2308.6716417
If we subtract 469 from 530, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 14:
The number 67 fits into 610 9 times, leaving a remainder of 7.
The next digit of our result is 9. 
Result so far: 2308.67164179
The remainder is 7 after subtracting 603 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 2308.67164179, with a leftover of 7e-09.
