We're dividing 21163113 by 396 
The aim is to understand the frequency of 396 in 21163113.

Going ahead to step 1:
The number 396 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 396

On to step 2:
When dividing 21 by 396, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 396

Step 3:
211 divided by 396 is 0 with a remainder of 211.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 211, we end up with 211.
Grab the next digit (6) from the dividend, add it to 211, then carry on: 2116 / 396

Advancing to step 4:
If we divide 2116 by 396, we get 5 and a remainder of 136.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 136 after subtracting 1980 from 2116.
Bring next digit (3) of the dividend behind the 136 and repeat the process: 1363 / 396

On to step 5:
When dividing 1363 by 396, we get 3 with a remainder of 175.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Subtracting 1188 from 1363 leaves us with 175.
Take the next digit (1) from the dividend and append it to 175, then repeat: 1751 / 396

On to step 6:
If we divide 1751 by 396, we get 4 and a remainder of 167.
The next digit of our result is 4. 
Result so far: 534.0
Subtract 1584 from 1751 to get 167.
Include the next digit (1) from the dividend after 167, then repeat: 1671 / 396

Moving on to step 7:
396 goes into 1671 4 times with a remainder of 87.
Use 4 as the next digit of our solution. 
Result so far: 5344.0
The remainder is 87 after subtracting 1584 from 1671.
Append the next digit (3) from the dividend to 87 and continue with: 873 / 396

On to step 8:
If we divide 873 by 396, we get 2 and a remainder of 81.
The next digit of our result is 2. 
Result so far: 53442.0
Subtract 792 from 873 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 9:
The number 396 fits into 810 2 times, leaving a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 53442.2
If we subtract 792 from 810, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
396 goes into 180 0 times with a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 53442.2
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 11:
If we divide 1800 by 396, we get 4 and a remainder of 216.
The next digit of our result is 4. 
Result so far: 53442.204
Subtract 1584 from 1800 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 12:
When dividing 2160 by 396, we get 5 with a remainder of 180.
Use 5 as the next digit of our solution. 
Result so far: 53442.2045
Subtract 1980 from 2160 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 13:
When dividing 1800 by 396, we get 4 with a remainder of 216.
Write down 4 as next digit of the result. 
Result so far: 53442.20454
The remainder is 216 after subtracting 1584 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 14:
When dividing 2160 by 396, we get 5 with a remainder of 180.
The number 5 becomes the next digit in our result. 
Result so far: 53442.204545
If we subtract 1980 from 2160, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 15:
If we divide 1800 by 396, we get 4 and a remainder of 216.
Write down 4 as next digit of the result. 
Result so far: 53442.2045454
If we subtract 1584 from 1800, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 16:
396 can be fit into 2160 5 times, resulting in a remainder of 180.
The next digit of our result is 5. 
Result so far: 53442.20454545
The remainder is 180 after subtracting 1980 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The quotient of the division is 53442.20454545, and the remainder is 1.8e-07.
