81734649 ÷ 623 
The aim is to understand the frequency of 623 in 81734649.

Going ahead to step 1:
623 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 623

On to step 2:
623 can be fit into 81 0 times, resulting in a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Include the next digit (7) from the dividend after 81, then repeat: 817 / 623

Step 3:
623 goes into 817 1 times with a remainder of 194.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 194 after subtracting 623 from 817.
Include the next digit (3) from the dividend after 194, then repeat: 1943 / 623

Going ahead to step 4:
1943 divided by 623 is 3 with a remainder of 74.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 1869 away from 1943, we end up with 74.
Take the next digit (4) from the dividend and append it to 74, then repeat: 744 / 623

Moving on to step 5:
744 divided by 623 is 1 with a remainder of 121.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
If we subtract 623 from 744, we get 121.
Bring next digit (6) of the dividend behind the 121 and repeat the process: 1216 / 623

Step 6:
When dividing 1216 by 623, we get 1 with a remainder of 593.
The next digit of our result is 1. 
Result so far: 1311.0
If we take 623 away from 1216, we end up with 593.
Append the next digit (4) from the dividend to 593 and continue with: 5934 / 623

Moving on to step 7:
5934 divided by 623 is 9 with a remainder of 327.
The next digit of our result is 9. 
Result so far: 13119.0
The remainder is 327 after subtracting 5607 from 5934.
Fetch the next digit (9) from the dividend, attach it to 327 and continue: 3279 / 623

Advancing to step 8:
The number 623 fits into 3279 5 times, leaving a remainder of 164.
Write down 5 as next digit of the result. 
Result so far: 131195.0
The remainder is 164 after subtracting 3115 from 3279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 9:
The number 623 fits into 1640 2 times, leaving a remainder of 394.
Put 2 as the next digit of the answer. 
Result so far: 131195.2
If we take 1246 away from 1640, we end up with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

On to step 10:
623 goes into 3940 6 times with a remainder of 202.
Put 6 as the next digit of the answer. 
Result so far: 131195.26
If we subtract 3738 from 3940, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 11:
When dividing 2020 by 623, we get 3 with a remainder of 151.
Put 3 as the next digit of the answer. 
Result so far: 131195.263
Deduct 1869 from 2020 and we're left with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 12:
When dividing 1510 by 623, we get 2 with a remainder of 264.
The next digit of our result is 2. 
Result so far: 131195.2632
If we subtract 1246 from 1510, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 13:
623 goes into 2640 4 times with a remainder of 148.
Record the quotient 4 as the next digit in the result. 
Result so far: 131195.26324
If we subtract 2492 from 2640, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 14:
623 can be fit into 1480 2 times, resulting in a remainder of 234.
Write down 2 as next digit of the result. 
Result so far: 131195.263242
If we subtract 1246 from 1480, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 15:
2340 divided by 623 is 3 with a remainder of 471.
Put 3 as the next digit of the answer. 
Result so far: 131195.2632423
Subtracting 1869 from 2340 leaves us with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

On to step 16:
When dividing 4710 by 623, we get 7 with a remainder of 349.
Write down 7 as next digit of the result. 
Result so far: 131195.26324237
If we subtract 4361 from 4710, we get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

The quotient of the division is 131195.26324237, and the remainder is 3.49e-07.
