84731743 ÷ 909 
The aim is to understand the frequency of 909 in 84731743.

Moving on to step 1:
If we divide 8 by 909, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 909

Step 2:
909 goes into 84 0 times with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Fetch the next digit (7) from the dividend, attach it to 84 and continue: 847 / 909

Step 3:
909 goes into 847 0 times with a remainder of 847.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 847, we get 847.
Grab the next digit (3) from the dividend, add it to 847, then carry on: 8473 / 909

Advancing to step 4:
909 can be fit into 8473 9 times, resulting in a remainder of 292.
The next digit of our result is 9. 
Result so far: 9.0
If we take 8181 away from 8473, we end up with 292.
Bring next digit (1) of the dividend behind the 292 and repeat the process: 2921 / 909

Going ahead to step 5:
When dividing 2921 by 909, we get 3 with a remainder of 194.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
Subtract 2727 from 2921 to get 194.
Take the next digit (7) from the dividend and append it to 194, then repeat: 1947 / 909

On to step 6:
1947 divided by 909 is 2 with a remainder of 129.
The next digit of our result is 2. 
Result so far: 932.0
If we take 1818 away from 1947, we end up with 129.
Grab the next digit (4) from the dividend, add it to 129, then carry on: 1294 / 909

On to step 7:
909 can be fit into 1294 1 times, resulting in a remainder of 385.
Record the quotient 1 as the next digit in the result. 
Result so far: 9321.0
If we take 909 away from 1294, we end up with 385.
Include the next digit (3) from the dividend after 385, then repeat: 3853 / 909

Moving on to step 8:
If we divide 3853 by 909, we get 4 and a remainder of 217.
Record the quotient 4 as the next digit in the result. 
Result so far: 93214.0
If we take 3636 away from 3853, we end up with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 9:
When dividing 2170 by 909, we get 2 with a remainder of 352.
The next digit of our result is 2. 
Result so far: 93214.2
Subtract 1818 from 2170 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 10:
If we divide 3520 by 909, we get 3 and a remainder of 793.
The next digit of our result is 3. 
Result so far: 93214.23
If we subtract 2727 from 3520, we get 793.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

Step 11:
If we divide 7930 by 909, we get 8 and a remainder of 658.
Write down 8 as next digit of the result. 
Result so far: 93214.238
If we subtract 7272 from 7930, we get 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Step 12:
When dividing 6580 by 909, we get 7 with a remainder of 217.
The number 7 becomes the next digit in our result. 
Result so far: 93214.2387
If we take 6363 away from 6580, we end up with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Advancing to step 13:
If we divide 2170 by 909, we get 2 and a remainder of 352.
The next digit of our result is 2. 
Result so far: 93214.23872
If we take 1818 away from 2170, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 14:
The number 909 fits into 3520 3 times, leaving a remainder of 793.
Put 3 as the next digit of the answer. 
Result so far: 93214.238723
Subtracting 2727 from 3520 leaves us with 793.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

On to step 15:
7930 divided by 909 is 8 with a remainder of 658.
The next digit of our result is 8. 
Result so far: 93214.2387238
If we subtract 7272 from 7930, we get 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

On to step 16:
When dividing 6580 by 909, we get 7 with a remainder of 217.
Record the quotient 7 as the next digit in the result. 
Result so far: 93214.23872387
Deduct 6363 from 6580 and we're left with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

The final outcome is 93214.23872387, with a leftover of 2.17e-07.
