Let's divide 99527960 by 402
The aim is to understand the frequency of 402 in 99527960.

On to step 1:
When dividing 9 by 402, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 402

Moving on to step 2:
402 goes into 99 0 times with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Bring next digit (5) of the dividend behind the 99 and repeat the process: 995 / 402

Let's proceed to step 3:
If we divide 995 by 402, we get 2 and a remainder of 191.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 804 from 995 to get 191.
Append the next digit (2) from the dividend to 191 and continue with: 1912 / 402

Moving on to step 4:
If we divide 1912 by 402, we get 4 and a remainder of 304.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we take 1608 away from 1912, we end up with 304.
Take the next digit (7) from the dividend and append it to 304, then repeat: 3047 / 402

Step 5:
When dividing 3047 by 402, we get 7 with a remainder of 233.
Write down 7 as next digit of the result. 
Result so far: 247.0
Subtract 2814 from 3047 to get 233.
Bring next digit (9) of the dividend behind the 233 and repeat the process: 2339 / 402

Going ahead to step 6:
The number 402 fits into 2339 5 times, leaving a remainder of 329.
The number 5 becomes the next digit in our result. 
Result so far: 2475.0
The remainder is 329 after subtracting 2010 from 2339.
Grab the next digit (6) from the dividend, add it to 329, then carry on: 3296 / 402

Moving on to step 7:
When dividing 3296 by 402, we get 8 with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 24758.0
Subtract 3216 from 3296 to get 80.
Take the next digit (0) from the dividend and append it to 80, then repeat: 800 / 402

Moving on to step 8:
800 divided by 402 is 1 with a remainder of 398.
Record the quotient 1 as the next digit in the result. 
Result so far: 247581.0
If we take 402 away from 800, we end up with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Going ahead to step 9:
402 goes into 3980 9 times with a remainder of 362.
The number 9 becomes the next digit in our result. 
Result so far: 247581.9
If we subtract 3618 from 3980, we get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

On to step 10:
If we divide 3620 by 402, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 247581.99
Subtract 3618 from 3620 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 247581.99, and the remainder is 0.002.
