We're dividing 71870 by 69 
The aim is to understand the frequency of 69 in 71870.

Let's proceed to step 1:
When dividing 7 by 69, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 69

Let's proceed to step 2:
When dividing 71 by 69, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 69 from 71 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 69

Step 3:
69 goes into 28 0 times with a remainder of 28.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 28, we end up with 28.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 69

Moving on to step 4:
The number 69 fits into 287 4 times, leaving a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 104.0
The remainder is 11 after subtracting 276 from 287.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 69

Advancing to step 5:
If we divide 110 by 69, we get 1 and a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 1041.0
The remainder is 41 after subtracting 69 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 6:
When dividing 410 by 69, we get 5 with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 1041.5
Subtract 345 from 410 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 7:
69 can be fit into 650 9 times, resulting in a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 1041.59
The remainder is 29 after subtracting 621 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 8:
If we divide 290 by 69, we get 4 and a remainder of 14.
The next digit of our result is 4. 
Result so far: 1041.594
If we subtract 276 from 290, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
69 can be fit into 140 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 1041.5942
Deduct 138 from 140 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.

On to step 10:
20 divided by 69 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1041.5942
If we subtract 0 from 20, we 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.

Going ahead to step 11:
69 goes into 200 2 times with a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 1041.594202
Subtracting 138 from 200 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 12:
69 can be fit into 620 8 times, resulting in a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 1041.5942028
Subtracting 552 from 620 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 13:
69 can be fit into 680 9 times, resulting in a remainder of 59.
Record the quotient 9 as the next digit in the result. 
Result so far: 1041.59420289
If we subtract 621 from 680, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Our division results in 1041.59420289 with a remaining 5.9e-08.
