Let's divide 87689230 by 412
The aim is to understand the frequency of 412 in 87689230.

On to step 1:
8 divided by 412 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 412

Advancing to step 2:
87 divided by 412 is 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Append the next digit (6) from the dividend to 87 and continue with: 876 / 412

On to step 3:
The number 412 fits into 876 2 times, leaving a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 824 away from 876, we end up with 52.
Bring next digit (8) of the dividend behind the 52 and repeat the process: 528 / 412

Advancing to step 4:
The number 412 fits into 528 1 times, leaving a remainder of 116.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtract 412 from 528 to get 116.
Bring next digit (9) of the dividend behind the 116 and repeat the process: 1169 / 412

Advancing to step 5:
If we divide 1169 by 412, we get 2 and a remainder of 345.
Use 2 as the next digit of our solution. 
Result so far: 212.0
Deduct 824 from 1169 and we're left with 345.
Bring next digit (2) of the dividend behind the 345 and repeat the process: 3452 / 412

Moving on to step 6:
3452 divided by 412 is 8 with a remainder of 156.
The next digit of our result is 8. 
Result so far: 2128.0
Subtract 3296 from 3452 to get 156.
Include the next digit (3) from the dividend after 156, then repeat: 1563 / 412

Step 7:
When dividing 1563 by 412, we get 3 with a remainder of 327.
Write down 3 as next digit of the result. 
Result so far: 21283.0
Subtracting 1236 from 1563 leaves us with 327.
Fetch the next digit (0) from the dividend, attach it to 327 and continue: 3270 / 412

Step 8:
If we divide 3270 by 412, we get 7 and a remainder of 386.
The number 7 becomes the next digit in our result. 
Result so far: 212837.0
If we subtract 2884 from 3270, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

On to step 9:
The number 412 fits into 3860 9 times, leaving a remainder of 152.
The number 9 becomes the next digit in our result. 
Result so far: 212837.9
Subtract 3708 from 3860 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 10:
412 can be fit into 1520 3 times, resulting in a remainder of 284.
Record the quotient 3 as the next digit in the result. 
Result so far: 212837.93
Subtracting 1236 from 1520 leaves us with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 11:
If we divide 2840 by 412, we get 6 and a remainder of 368.
Use 6 as the next digit of our solution. 
Result so far: 212837.936
If we take 2472 away from 2840, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 12:
412 can be fit into 3680 8 times, resulting in a remainder of 384.
Put 8 as the next digit of the answer. 
Result so far: 212837.9368
The remainder is 384 after subtracting 3296 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 13:
When dividing 3840 by 412, we get 9 with a remainder of 132.
Write down 9 as next digit of the result. 
Result so far: 212837.93689
If we subtract 3708 from 3840, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 14:
If we divide 1320 by 412, we get 3 and a remainder of 84.
Write down 3 as next digit of the result. 
Result so far: 212837.936893
If we subtract 1236 from 1320, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 15:
412 can be fit into 840 2 times, resulting in a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 212837.9368932
The remainder is 16 after subtracting 824 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 16:
412 can be fit into 160 0 times, resulting in a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 212837.9368932
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

After the division, we end up with 212837.9368932 and a remainder of 1.6e-07.
