66892560 divided by 172 
The aim is to understand the frequency of 172 in 66892560.

Moving on to step 1:
When dividing 6 by 172, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
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 / 172

Advancing to step 2:
172 can be fit into 66 0 times, resulting in a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Take the next digit (8) from the dividend and append it to 66, then repeat: 668 / 172

On to step 3:
172 can be fit into 668 3 times, resulting in a remainder of 152.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 152 after subtracting 516 from 668.
Bring next digit (9) of the dividend behind the 152 and repeat the process: 1529 / 172

Going ahead to step 4:
172 goes into 1529 8 times with a remainder of 153.
The next digit of our result is 8. 
Result so far: 38.0
If we subtract 1376 from 1529, we get 153.
Include the next digit (2) from the dividend after 153, then repeat: 1532 / 172

Let's proceed to step 5:
If we divide 1532 by 172, we get 8 and a remainder of 156.
Put 8 as the next digit of the answer. 
Result so far: 388.0
If we take 1376 away from 1532, we end up with 156.
Fetch the next digit (5) from the dividend, attach it to 156 and continue: 1565 / 172

Going ahead to step 6:
1565 divided by 172 is 9 with a remainder of 17.
The next digit of our result is 9. 
Result so far: 3889.0
The remainder is 17 after subtracting 1548 from 1565.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 172

Moving on to step 7:
176 divided by 172 is 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 38891.0
Subtract 172 from 176 to get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 172

Step 8:
The number 172 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 388910.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
The number 172 fits into 400 2 times, leaving a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 388910.2
Subtract 344 from 400 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 10:
The number 172 fits into 560 3 times, leaving a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 388910.23
If we subtract 516 from 560, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 11:
When dividing 440 by 172, we get 2 with a remainder of 96.
Put 2 as the next digit of the answer. 
Result so far: 388910.232
If we take 344 away from 440, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 12:
If we divide 960 by 172, we get 5 and a remainder of 100.
The next digit of our result is 5. 
Result so far: 388910.2325
The remainder is 100 after subtracting 860 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 13:
If we divide 1000 by 172, we get 5 and a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 388910.23255
If we subtract 860 from 1000, we 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.

The quotient of the division is 388910.23255, and the remainder is 0.00014.
