890423 ÷ 69 
The aim is to understand the frequency of 69 in 890423.

On to step 1:
When dividing 8 by 69, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 69

Advancing to step 2:
69 goes into 89 1 times with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 69 away from 89, we end up with 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 69

Step 3:
When dividing 200 by 69, we get 2 with a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 138 away from 200, we end up with 62.
Append the next digit (4) from the dividend to 62 and continue with: 624 / 69

On to step 4:
When dividing 624 by 69, we get 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 129.0
If we take 621 away from 624, we end up with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 69

Going ahead to step 5:
69 goes into 32 0 times with a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 1290.0
The remainder is 32 after subtracting 0 from 32.
Append the next digit (3) from the dividend to 32 and continue with: 323 / 69

Advancing to step 6:
When dividing 323 by 69, we get 4 with a remainder of 47.
The next digit of our result is 4. 
Result so far: 12904.0
If we subtract 276 from 323, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 7:
69 goes into 470 6 times with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 12904.6
If we take 414 away from 470, 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.

Moving on to step 8:
69 can be fit into 560 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 12904.68
If we subtract 552 from 560, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
When dividing 80 by 69, we get 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 12904.681
Subtract 69 from 80 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 10:
If we divide 110 by 69, we get 1 and a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 12904.6811
Subtract 69 from 110 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

After the division, we end up with 12904.6811 and a remainder of 0.00041.
