213168 divided by 67 
The aim is to understand the frequency of 67 in 213168.

On to step 1:
If we divide 2 by 67, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 67

On to step 2:
If we divide 21 by 67, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 67

Going ahead to step 3:
67 can be fit into 213 3 times, resulting in a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 201 from 213 and we're left with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 67

Moving on to step 4:
67 can be fit into 121 1 times, resulting in a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we take 67 away from 121, we end up with 54.
Fetch the next digit (6) from the dividend, attach it to 54 and continue: 546 / 67

On to step 5:
When dividing 546 by 67, we get 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 318.0
The remainder is 10 after subtracting 536 from 546.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 67

Step 6:
When dividing 108 by 67, we get 1 with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 3181.0
Deduct 67 from 108 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
410 divided by 67 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 3181.6
If we take 402 away from 410, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
If we divide 80 by 67, we get 1 and a remainder of 13.
The next digit of our result is 1. 
Result so far: 3181.61
If we subtract 67 from 80, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
67 goes into 130 1 times with a remainder of 63.
Use 1 as the next digit of our solution. 
Result so far: 3181.611
The remainder is 63 after subtracting 67 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The final outcome is 3181.611, with a leftover of 0.0063.
