27786473 divided by 402 
The aim is to understand the frequency of 402 in 27786473.

On to step 1:
402 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 402

Let's proceed to step 2:
27 divided by 402 is 0 with a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Bring next digit (7) of the dividend behind the 27 and repeat the process: 277 / 402

Let's proceed to step 3:
402 can be fit into 277 0 times, resulting in a remainder of 277.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 277, we get 277.
Take the next digit (8) from the dividend and append it to 277, then repeat: 2778 / 402

Going ahead to step 4:
If we divide 2778 by 402, we get 6 and a remainder of 366.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 2412 from 2778 and we're left with 366.
Take the next digit (6) from the dividend and append it to 366, then repeat: 3666 / 402

Advancing to step 5:
The number 402 fits into 3666 9 times, leaving a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 69.0
Subtracting 3618 from 3666 leaves us with 48.
Append the next digit (4) from the dividend to 48 and continue with: 484 / 402

Step 6:
When dividing 484 by 402, we get 1 with a remainder of 82.
The number 1 becomes the next digit in our result. 
Result so far: 691.0
Subtract 402 from 484 to get 82.
Append the next digit (7) from the dividend to 82 and continue with: 827 / 402

Advancing to step 7:
827 divided by 402 is 2 with a remainder of 23.
Write down 2 as next digit of the result. 
Result so far: 6912.0
Deduct 804 from 827 and we're left with 23.
Append the next digit (3) from the dividend to 23 and continue with: 233 / 402

Let's proceed to step 8:
402 goes into 233 0 times with a remainder of 233.
Record the quotient 0 as the next digit in the result. 
Result so far: 69120.0
If we take 0 away from 233, we end up with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Moving on to step 9:
If we divide 2330 by 402, we get 5 and a remainder of 320.
Record the quotient 5 as the next digit in the result. 
Result so far: 69120.5
Subtracting 2010 from 2330 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 10:
The number 402 fits into 3200 7 times, leaving a remainder of 386.
Put 7 as the next digit of the answer. 
Result so far: 69120.57
If we subtract 2814 from 3200, 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.

Moving on to step 11:
When dividing 3860 by 402, we get 9 with a remainder of 242.
The next digit of our result is 9. 
Result so far: 69120.579
The remainder is 242 after subtracting 3618 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 12:
If we divide 2420 by 402, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 69120.5796
If we subtract 2412 from 2420, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
402 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 69120.5796
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
402 goes into 800 1 times with a remainder of 398.
Write down 1 as next digit of the result. 
Result so far: 69120.579601
If we subtract 402 from 800, we get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Advancing to step 15:
When dividing 3980 by 402, we get 9 with a remainder of 362.
Put 9 as the next digit of the answer. 
Result so far: 69120.5796019
Subtracting 3618 from 3980 leaves us with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Advancing to step 16:
402 can be fit into 3620 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 69120.57960199
If we subtract 3618 from 3620, we 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.

After the division, we end up with 69120.57960199 and a remainder of 2e-09.
