Let's divide 859890 by 69
The aim is to understand the frequency of 69 in 859890.

Moving on to step 1:
8 divided by 69 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 69

On to step 2:
If we divide 85 by 69, we get 1 and a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 69 away from 85, we end up with 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 69

Advancing to step 3:
When dividing 169 by 69, we get 2 with a remainder of 31.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 31 after subtracting 138 from 169.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 69

Let's proceed to step 4:
318 divided by 69 is 4 with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 124.0
If we take 276 away from 318, we end up with 42.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 69

Going ahead to step 5:
When dividing 429 by 69, we get 6 with a remainder of 15.
The next digit of our result is 6. 
Result so far: 1246.0
If we subtract 414 from 429, we get 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 69

Moving on to step 6:
69 goes into 150 2 times with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 12462.0
If we subtract 138 from 150, 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.

Advancing to step 7:
The number 69 fits into 120 1 times, leaving a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 12462.1
Deduct 69 from 120 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 8:
510 divided by 69 is 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 12462.17
If we take 483 away from 510, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
69 can be fit into 270 3 times, resulting in a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 12462.173
The remainder is 63 after subtracting 207 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 10:
69 goes into 630 9 times with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 12462.1739
The remainder is 9 after subtracting 621 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 11:
When dividing 90 by 69, we get 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 12462.17391
Deduct 69 from 90 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.

Going ahead to step 12:
The number 69 fits into 210 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 12462.173913
The remainder is 3 after subtracting 207 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 13:
30 divided by 69 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 12462.173913
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
The number 69 fits into 300 4 times, leaving a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 12462.17391304
The remainder is 24 after subtracting 276 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 12462.17391304, and the remainder is 2.4e-08.
