810018 ÷ 68 
The aim is to understand the frequency of 68 in 810018.

On to step 1:
68 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 68

Moving on to step 2:
81 divided by 68 is 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 68 from 81 to get 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 68

Moving on to step 3:
130 divided by 68 is 1 with a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 68 from 130 to get 62.
Fetch the next digit (0) from the dividend, attach it to 62 and continue: 620 / 68

Let's proceed to step 4:
When dividing 620 by 68, we get 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
If we take 612 away from 620, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 68

Advancing to step 5:
68 can be fit into 81 1 times, resulting in a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1191.0
If we subtract 68 from 81, we get 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 68

Let's proceed to step 6:
68 goes into 138 2 times with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 11912.0
Deduct 136 from 138 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
When dividing 20 by 68, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 11912.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
68 can be fit into 200 2 times, resulting in a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 11912.02
If we take 136 away from 200, we end up 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.

Advancing to step 9:
The number 68 fits into 640 9 times, leaving a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 11912.029
Subtracting 612 from 640 leaves us 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 10:
If we divide 280 by 68, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 11912.0294
Deduct 272 from 280 and we're left 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 11:
68 goes into 80 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 11912.02941
If we subtract 68 from 80, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
120 divided by 68 is 1 with a remainder of 52.
Write down 1 as next digit of the result. 
Result so far: 11912.029411
Deduct 68 from 120 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 11912.029411 with a remaining 5.2e-06.
