We divide 850843 by 69
The aim is to understand the frequency of 69 in 850843.

Going ahead to step 1:
When dividing 8 by 69, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 69

Let's proceed to step 2:
69 can be fit into 85 1 times, resulting in a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 69 from 85 and we're left with 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 69

Moving on to step 3:
If we divide 160 by 69, we get 2 and a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 138 from 160 leaves us with 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 69

On to step 4:
The number 69 fits into 228 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
Subtracting 207 from 228 leaves us with 21.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 69

Moving on to step 5:
The number 69 fits into 214 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 1233.0
Deduct 207 from 214 and we're left with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 69

On to step 6:
The number 69 fits into 73 1 times, leaving a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 12331.0
Subtract 69 from 73 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
The number 69 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 12331.0
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
The number 69 fits into 400 5 times, leaving a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 12331.05
Subtract 345 from 400 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 9:
The number 69 fits into 550 7 times, leaving a remainder of 67.
The next digit of our result is 7. 
Result so far: 12331.057
Subtracting 483 from 550 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 10:
When dividing 670 by 69, we get 9 with a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 12331.0579
Subtract 621 from 670 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 11:
490 divided by 69 is 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 12331.05797
Subtract 483 from 490 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 12:
When dividing 70 by 69, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 12331.057971
The remainder is 1 after subtracting 69 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 13:
The number 69 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 12331.057971
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
When dividing 100 by 69, we get 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 12331.05797101
Deduct 69 from 100 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

After the division, we end up with 12331.05797101 and a remainder of 3.1e-08.
