We divide 853489 by 68
The aim is to understand the frequency of 68 in 853489.

Step 1:
When dividing 8 by 68, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 68

Step 2:
85 divided by 68 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 68 from 85 and we're left with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 68

On to step 3:
68 goes into 173 2 times with a remainder of 37.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 136 from 173, we get 37.
Fetch the next digit (4) from the dividend, attach it to 37 and continue: 374 / 68

Going ahead to step 4:
If we divide 374 by 68, we get 5 and a remainder of 34.
Put 5 as the next digit of the answer. 
Result so far: 125.0
Deduct 340 from 374 and we're left with 34.
Fetch the next digit (8) from the dividend, attach it to 34 and continue: 348 / 68

Let's proceed to step 5:
If we divide 348 by 68, we get 5 and a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 1255.0
If we take 340 away from 348, we end up with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 68

Advancing to step 6:
The number 68 fits into 89 1 times, leaving a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 12551.0
Deduct 68 from 89 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
If we divide 210 by 68, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 12551.3
Deduct 204 from 210 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
68 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 12551.3
If we take 0 away from 60, we end up 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.

Going ahead to step 9:
600 divided by 68 is 8 with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 12551.308
If we take 544 away from 600, we end up 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.

Going ahead to step 10:
The number 68 fits into 560 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 12551.3088
Subtract 544 from 560 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 12551.3088 with a remaining 0.00016.
