Let's divide 66209843 by 476
The aim is to understand the frequency of 476 in 66209843.

Going ahead to step 1:
When dividing 6 by 476, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 476

Advancing to step 2:
If we divide 66 by 476, we get 0 and a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Bring next digit (2) of the dividend behind the 66 and repeat the process: 662 / 476

Moving on to step 3:
662 divided by 476 is 1 with a remainder of 186.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 476 from 662, we get 186.
Grab the next digit (0) from the dividend, add it to 186, then carry on: 1860 / 476

Let's proceed to step 4:
1860 divided by 476 is 3 with a remainder of 432.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1428 from 1860 to get 432.
Bring next digit (9) of the dividend behind the 432 and repeat the process: 4329 / 476

Moving on to step 5:
476 goes into 4329 9 times with a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 139.0
Deduct 4284 from 4329 and we're left with 45.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 476

Step 6:
476 can be fit into 458 0 times, resulting in a remainder of 458.
The number 0 becomes the next digit in our result. 
Result so far: 1390.0
If we subtract 0 from 458, we get 458.
Bring next digit (4) of the dividend behind the 458 and repeat the process: 4584 / 476

Going ahead to step 7:
476 can be fit into 4584 9 times, resulting in a remainder of 300.
Record the quotient 9 as the next digit in the result. 
Result so far: 13909.0
Subtracting 4284 from 4584 leaves us with 300.
Append the next digit (3) from the dividend to 300 and continue with: 3003 / 476

Let's proceed to step 8:
3003 divided by 476 is 6 with a remainder of 147.
The next digit of our result is 6. 
Result so far: 139096.0
Subtract 2856 from 3003 to get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Step 9:
If we divide 1470 by 476, we get 3 and a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 139096.3
Subtracting 1428 from 1470 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
The number 476 fits into 420 0 times, leaving a remainder of 420.
Use 0 as the next digit of our solution. 
Result so far: 139096.3
The remainder is 420 after subtracting 0 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 11:
4200 divided by 476 is 8 with a remainder of 392.
Put 8 as the next digit of the answer. 
Result so far: 139096.308
The remainder is 392 after subtracting 3808 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 12:
476 can be fit into 3920 8 times, resulting in a remainder of 112.
Write down 8 as next digit of the result. 
Result so far: 139096.3088
If we take 3808 away from 3920, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final result is 139096.3088 with a remainder of 0.00112.
