We look at the division of 47577642 by 396 
The aim is to understand the frequency of 396 in 47577642.

On to step 1:
When dividing 4 by 396, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 396

Moving on to step 2:
When dividing 47 by 396, we get 0 with a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 47, we get 47.
Grab the next digit (5) from the dividend, add it to 47, then carry on: 475 / 396

Moving on to step 3:
475 divided by 396 is 1 with a remainder of 79.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 396 from 475 and we're left with 79.
Take the next digit (7) from the dividend and append it to 79, then repeat: 797 / 396

Going ahead to step 4:
396 can be fit into 797 2 times, resulting in a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 792 away from 797, we end up with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 396

Let's proceed to step 5:
57 divided by 396 is 0 with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 120.0
Subtracting 0 from 57 leaves us with 57.
Bring next digit (6) of the dividend behind the 57 and repeat the process: 576 / 396

Step 6:
576 divided by 396 is 1 with a remainder of 180.
Use 1 as the next digit of our solution. 
Result so far: 1201.0
The remainder is 180 after subtracting 396 from 576.
Grab the next digit (4) from the dividend, add it to 180, then carry on: 1804 / 396

Going ahead to step 7:
If we divide 1804 by 396, we get 4 and a remainder of 220.
The next digit of our result is 4. 
Result so far: 12014.0
If we subtract 1584 from 1804, we get 220.
Append the next digit (2) from the dividend to 220 and continue with: 2202 / 396

Step 8:
396 goes into 2202 5 times with a remainder of 222.
Record the quotient 5 as the next digit in the result. 
Result so far: 120145.0
Deduct 1980 from 2202 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Moving on to step 9:
When dividing 2220 by 396, we get 5 with a remainder of 240.
The number 5 becomes the next digit in our result. 
Result so far: 120145.5
Subtract 1980 from 2220 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 10:
The number 396 fits into 2400 6 times, leaving a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 120145.56
Deduct 2376 from 2400 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
396 goes into 240 0 times with a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 120145.56
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 12:
396 can be fit into 2400 6 times, resulting in a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 120145.5606
If we take 2376 away from 2400, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
240 divided by 396 is 0 with a remainder of 240.
The next digit of our result is 0. 
Result so far: 120145.5606
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 14:
2400 divided by 396 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 120145.560606
Subtract 2376 from 2400 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 15:
240 divided by 396 is 0 with a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 120145.560606
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 16:
The number 396 fits into 2400 6 times, leaving a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 120145.56060606
Subtracting 2376 from 2400 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 120145.56060606 with a remainder of 2.4e-08.
