66566921 ÷ 162 
The aim is to understand the frequency of 162 in 66566921.

Going ahead to step 1:
162 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 162

Moving on to step 2:
162 goes into 66 0 times with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Grab the next digit (5) from the dividend, add it to 66, then carry on: 665 / 162

Let's proceed to step 3:
When dividing 665 by 162, we get 4 with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 648 from 665, we get 17.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 162

Let's proceed to step 4:
If we divide 176 by 162, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Deduct 162 from 176 and we're left with 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 162

Going ahead to step 5:
If we divide 146 by 162, we get 0 and a remainder of 146.
Put 0 as the next digit of the answer. 
Result so far: 410.0
The remainder is 146 after subtracting 0 from 146.
Take the next digit (9) from the dividend and append it to 146, then repeat: 1469 / 162

On to step 6:
If we divide 1469 by 162, we get 9 and a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 4109.0
If we take 1458 away from 1469, we end up with 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 162

On to step 7:
The number 162 fits into 112 0 times, leaving a remainder of 112.
Put 0 as the next digit of the answer. 
Result so far: 41090.0
If we take 0 away from 112, we end up with 112.
Include the next digit (1) from the dividend after 112, then repeat: 1121 / 162

On to step 8:
The number 162 fits into 1121 6 times, leaving a remainder of 149.
The number 6 becomes the next digit in our result. 
Result so far: 410906.0
Deduct 972 from 1121 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

On to step 9:
162 goes into 1490 9 times with a remainder of 32.
The next digit of our result is 9. 
Result so far: 410906.9
Subtracting 1458 from 1490 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
162 goes into 320 1 times with a remainder of 158.
Use 1 as the next digit of our solution. 
Result so far: 410906.91
Deduct 162 from 320 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Going ahead to step 11:
The number 162 fits into 1580 9 times, leaving a remainder of 122.
Write down 9 as next digit of the result. 
Result so far: 410906.919
Subtracting 1458 from 1580 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 12:
162 goes into 1220 7 times with a remainder of 86.
Write down 7 as next digit of the result. 
Result so far: 410906.9197
If we take 1134 away from 1220, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 13:
162 can be fit into 860 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 410906.91975
Deduct 810 from 860 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
The number 162 fits into 500 3 times, leaving a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 410906.919753
If we subtract 486 from 500, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 15:
If we divide 140 by 162, we get 0 and a remainder of 140.
The next digit of our result is 0. 
Result so far: 410906.919753
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 16:
162 can be fit into 1400 8 times, resulting in a remainder of 104.
The number 8 becomes the next digit in our result. 
Result so far: 410906.91975308
Subtract 1296 from 1400 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The quotient of the division is 410906.91975308, and the remainder is 1.04e-07.
