We divide 86018709 by 402
The aim is to understand the frequency of 402 in 86018709.

Let's proceed to step 1:
8 divided by 402 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.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 402

Advancing to step 2:
402 can be fit into 86 0 times, resulting in a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Bring next digit (0) of the dividend behind the 86 and repeat the process: 860 / 402

Going ahead to step 3:
402 can be fit into 860 2 times, resulting in a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 804 from 860 leaves us with 56.
Include the next digit (1) from the dividend after 56, then repeat: 561 / 402

Moving on to step 4:
561 divided by 402 is 1 with a remainder of 159.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 402 away from 561, we end up with 159.
Include the next digit (8) from the dividend after 159, then repeat: 1598 / 402

Going ahead to step 5:
402 can be fit into 1598 3 times, resulting in a remainder of 392.
Write down 3 as next digit of the result. 
Result so far: 213.0
Subtracting 1206 from 1598 leaves us with 392.
Take the next digit (7) from the dividend and append it to 392, then repeat: 3927 / 402

On to step 6:
When dividing 3927 by 402, we get 9 with a remainder of 309.
The next digit of our result is 9. 
Result so far: 2139.0
The remainder is 309 after subtracting 3618 from 3927.
Append the next digit (0) from the dividend to 309 and continue with: 3090 / 402

Moving on to step 7:
3090 divided by 402 is 7 with a remainder of 276.
The number 7 becomes the next digit in our result. 
Result so far: 21397.0
If we take 2814 away from 3090, we end up with 276.
Grab the next digit (9) from the dividend, add it to 276, then carry on: 2769 / 402

Moving on to step 8:
When dividing 2769 by 402, we get 6 with a remainder of 357.
Record the quotient 6 as the next digit in the result. 
Result so far: 213976.0
Subtracting 2412 from 2769 leaves us with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Moving on to step 9:
402 goes into 3570 8 times with a remainder of 354.
Put 8 as the next digit of the answer. 
Result so far: 213976.8
Subtract 3216 from 3570 to get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Advancing to step 10:
When dividing 3540 by 402, we get 8 with a remainder of 324.
Use 8 as the next digit of our solution. 
Result so far: 213976.88
The remainder is 324 after subtracting 3216 from 3540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

In conclusion, the division gives 213976.88 with a balance of 0.324.
