We look at the division of 69876139 by 412 
The aim is to understand the frequency of 412 in 69876139.

Advancing to step 1:
If we divide 6 by 412, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 412

Advancing to step 2:
412 goes into 69 0 times with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Bring next digit (8) of the dividend behind the 69 and repeat the process: 698 / 412

Let's proceed to step 3:
The number 412 fits into 698 1 times, leaving a remainder of 286.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 412 from 698 and we're left with 286.
Take the next digit (7) from the dividend and append it to 286, then repeat: 2867 / 412

Moving on to step 4:
When dividing 2867 by 412, we get 6 with a remainder of 395.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 395 after subtracting 2472 from 2867.
Fetch the next digit (6) from the dividend, attach it to 395 and continue: 3956 / 412

Step 5:
When dividing 3956 by 412, we get 9 with a remainder of 248.
The next digit of our result is 9. 
Result so far: 169.0
Subtract 3708 from 3956 to get 248.
Grab the next digit (1) from the dividend, add it to 248, then carry on: 2481 / 412

Moving on to step 6:
The number 412 fits into 2481 6 times, leaving a remainder of 9.
The next digit of our result is 6. 
Result so far: 1696.0
Subtracting 2472 from 2481 leaves us with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 412

On to step 7:
93 divided by 412 is 0 with a remainder of 93.
Record the quotient 0 as the next digit in the result. 
Result so far: 16960.0
Deduct 0 from 93 and we're left with 93.
Append the next digit (9) from the dividend to 93 and continue with: 939 / 412

Going ahead to step 8:
412 goes into 939 2 times with a remainder of 115.
Write down 2 as next digit of the result. 
Result so far: 169602.0
If we take 824 away from 939, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 9:
1150 divided by 412 is 2 with a remainder of 326.
The next digit of our result is 2. 
Result so far: 169602.2
Subtract 824 from 1150 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 10:
When dividing 3260 by 412, we get 7 with a remainder of 376.
Use 7 as the next digit of our solution. 
Result so far: 169602.27
Subtracting 2884 from 3260 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 11:
3760 divided by 412 is 9 with a remainder of 52.
Write down 9 as next digit of the result. 
Result so far: 169602.279
Subtract 3708 from 3760 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 12:
520 divided by 412 is 1 with a remainder of 108.
Put 1 as the next digit of the answer. 
Result so far: 169602.2791
If we take 412 away from 520, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 13:
412 can be fit into 1080 2 times, resulting in a remainder of 256.
Write down 2 as next digit of the result. 
Result so far: 169602.27912
Deduct 824 from 1080 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 14:
When dividing 2560 by 412, we get 6 with a remainder of 88.
The next digit of our result is 6. 
Result so far: 169602.279126
If we subtract 2472 from 2560, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 15:
When dividing 880 by 412, we get 2 with a remainder of 56.
The next digit of our result is 2. 
Result so far: 169602.2791262
Deduct 824 from 880 and we're left 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.

Let's proceed to step 16:
412 goes into 560 1 times with a remainder of 148.
Put 1 as the next digit of the answer. 
Result so far: 169602.27912621
The remainder is 148 after subtracting 412 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

The quotient of the division is 169602.27912621, and the remainder is 1.48e-07.
