777858 ÷ 67 
The aim is to understand the frequency of 67 in 777858.

Step 1:
When dividing 7 by 67, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 67

On to step 2:
67 goes into 77 1 times with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 67 from 77 leaves us with 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 67

Advancing to step 3:
67 goes into 107 1 times with a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 67 away from 107, we end up with 40.
Include the next digit (8) from the dividend after 40, then repeat: 408 / 67

Step 4:
67 can be fit into 408 6 times, resulting in a remainder of 6.
The next digit of our result is 6. 
Result so far: 116.0
If we subtract 402 from 408, we get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 67

Moving on to step 5:
If we divide 65 by 67, we get 0 and a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 1160.0
The remainder is 65 after subtracting 0 from 65.
Include the next digit (8) from the dividend after 65, then repeat: 658 / 67

On to step 6:
67 can be fit into 658 9 times, resulting in a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 11609.0
If we subtract 603 from 658, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 7:
When dividing 550 by 67, we get 8 with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 11609.8
The remainder is 14 after subtracting 536 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
If we divide 140 by 67, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 11609.82
Subtract 134 from 140 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
If we divide 60 by 67, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 11609.82
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
600 divided by 67 is 8 with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 11609.8208
Deduct 536 from 600 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 11:
If we divide 640 by 67, we get 9 and a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 11609.82089
Subtracting 603 from 640 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 12:
The number 67 fits into 370 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 11609.820895
If we take 335 away from 370, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 13:
If we divide 350 by 67, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 11609.8208955
If we subtract 335 from 350, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 11609.8208955, with a leftover of 1.5e-07.
