Let's divide 98172177 by 810
The aim is to understand the frequency of 810 in 98172177.

Let's proceed to step 1:
9 divided by 810 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 810

Step 2:
When dividing 98 by 810, we get 0 with a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 98 leaves us with 98.
Fetch the next digit (1) from the dividend, attach it to 98 and continue: 981 / 810

On to step 3:
981 divided by 810 is 1 with a remainder of 171.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 810 from 981 leaves us with 171.
Take the next digit (7) from the dividend and append it to 171, then repeat: 1717 / 810

Moving on to step 4:
1717 divided by 810 is 2 with a remainder of 97.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 1620 from 1717 to get 97.
Include the next digit (2) from the dividend after 97, then repeat: 972 / 810

Let's proceed to step 5:
When dividing 972 by 810, we get 1 with a remainder of 162.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
If we subtract 810 from 972, we get 162.
Grab the next digit (1) from the dividend, add it to 162, then carry on: 1621 / 810

Advancing to step 6:
When dividing 1621 by 810, we get 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 1212.0
If we subtract 1620 from 1621, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 810

Advancing to step 7:
17 divided by 810 is 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 12120.0
If we subtract 0 from 17, we get 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 810

Let's proceed to step 8:
When dividing 177 by 810, we get 0 with a remainder of 177.
The next digit of our result is 0. 
Result so far: 121200.0
If we take 0 away from 177, we end up with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Moving on to step 9:
810 can be fit into 1770 2 times, resulting in a remainder of 150.
Write down 2 as next digit of the result. 
Result so far: 121200.2
The remainder is 150 after subtracting 1620 from 1770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 10:
1500 divided by 810 is 1 with a remainder of 690.
The next digit of our result is 1. 
Result so far: 121200.21
If we take 810 away from 1500, we end up with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Let's proceed to step 11:
6900 divided by 810 is 8 with a remainder of 420.
The next digit of our result is 8. 
Result so far: 121200.218
Deduct 6480 from 6900 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 12:
4200 divided by 810 is 5 with a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 121200.2185
Subtract 4050 from 4200 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 13:
The number 810 fits into 1500 1 times, leaving a remainder of 690.
The number 1 becomes the next digit in our result. 
Result so far: 121200.21851
If we take 810 away from 1500, we end up with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Moving on to step 14:
The number 810 fits into 6900 8 times, leaving a remainder of 420.
Record the quotient 8 as the next digit in the result. 
Result so far: 121200.218518
The remainder is 420 after subtracting 6480 from 6900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 15:
If we divide 4200 by 810, we get 5 and a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 121200.2185185
The remainder is 150 after subtracting 4050 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 16:
1500 divided by 810 is 1 with a remainder of 690.
Use 1 as the next digit of our solution. 
Result so far: 121200.21851851
If we subtract 810 from 1500, we get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

The final result is 121200.21851851 with a remainder of 6.9e-07.
