831690 ÷ 67 
The aim is to understand the frequency of 67 in 831690.

On to step 1:
When dividing 8 by 67, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 67

On to step 2:
67 can be fit into 83 1 times, resulting in a remainder of 16.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 67 from 83, we get 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 67

Moving on to step 3:
The number 67 fits into 161 2 times, leaving a remainder of 27.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 134 from 161 leaves us with 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 67

Advancing to step 4:
67 goes into 276 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 124.0
Subtract 268 from 276 to get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 67

Advancing to step 5:
67 goes into 89 1 times with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1241.0
Subtract 67 from 89 to get 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 67

Going ahead to step 6:
The number 67 fits into 220 3 times, leaving a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 12413.0
Deduct 201 from 220 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
When dividing 190 by 67, we get 2 with a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 12413.2
Deduct 134 from 190 and we're left 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 8:
When dividing 560 by 67, we get 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 12413.28
If we take 536 away from 560, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
240 divided by 67 is 3 with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 12413.283
If we take 201 away from 240, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 10:
If we divide 390 by 67, we get 5 and a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 12413.2835
The remainder is 55 after subtracting 335 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 11:
67 goes into 550 8 times with a remainder of 14.
The next digit of our result is 8. 
Result so far: 12413.28358
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.

On to step 12:
When dividing 140 by 67, we get 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 12413.283582
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.

Going ahead to step 13:
When dividing 60 by 67, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 12413.283582
The remainder is 60 after subtracting 0 from 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 14:
When dividing 600 by 67, we get 8 with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 12413.28358208
Subtract 536 from 600 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 12413.28358208 and a remainder of 6.4e-08.
