30107183 divided by 523 
The aim is to understand the frequency of 523 in 30107183.

On to step 1:
When dividing 3 by 523, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 523

Moving on to step 2:
523 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 523

Moving on to step 3:
If we divide 301 by 523, we get 0 and a remainder of 301.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 301 leaves us with 301.
Bring next digit (0) of the dividend behind the 301 and repeat the process: 3010 / 523

Let's proceed to step 4:
523 can be fit into 3010 5 times, resulting in a remainder of 395.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 2615 from 3010 to get 395.
Include the next digit (7) from the dividend after 395, then repeat: 3957 / 523

Going ahead to step 5:
The number 523 fits into 3957 7 times, leaving a remainder of 296.
Put 7 as the next digit of the answer. 
Result so far: 57.0
If we take 3661 away from 3957, we end up with 296.
Include the next digit (1) from the dividend after 296, then repeat: 2961 / 523

On to step 6:
When dividing 2961 by 523, we get 5 with a remainder of 346.
Put 5 as the next digit of the answer. 
Result so far: 575.0
Deduct 2615 from 2961 and we're left with 346.
Include the next digit (8) from the dividend after 346, then repeat: 3468 / 523

Advancing to step 7:
3468 divided by 523 is 6 with a remainder of 330.
Write down 6 as next digit of the result. 
Result so far: 5756.0
Subtracting 3138 from 3468 leaves us with 330.
Grab the next digit (3) from the dividend, add it to 330, then carry on: 3303 / 523

Let's proceed to step 8:
3303 divided by 523 is 6 with a remainder of 165.
Write down 6 as next digit of the result. 
Result so far: 57566.0
Deduct 3138 from 3303 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 9:
523 goes into 1650 3 times with a remainder of 81.
Record the quotient 3 as the next digit in the result. 
Result so far: 57566.3
If we take 1569 away from 1650, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 10:
The number 523 fits into 810 1 times, leaving a remainder of 287.
The next digit of our result is 1. 
Result so far: 57566.31
Subtract 523 from 810 to get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Going ahead to step 11:
The number 523 fits into 2870 5 times, leaving a remainder of 255.
Use 5 as the next digit of our solution. 
Result so far: 57566.315
Subtracting 2615 from 2870 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 12:
523 goes into 2550 4 times with a remainder of 458.
The number 4 becomes the next digit in our result. 
Result so far: 57566.3154
If we take 2092 away from 2550, we end up with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Moving on to step 13:
4580 divided by 523 is 8 with a remainder of 396.
The number 8 becomes the next digit in our result. 
Result so far: 57566.31548
Subtracting 4184 from 4580 leaves us with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 14:
523 can be fit into 3960 7 times, resulting in a remainder of 299.
Use 7 as the next digit of our solution. 
Result so far: 57566.315487
If we subtract 3661 from 3960, we get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Advancing to step 15:
523 goes into 2990 5 times with a remainder of 375.
The next digit of our result is 5. 
Result so far: 57566.3154875
If we take 2615 away from 2990, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

On to step 16:
The number 523 fits into 3750 7 times, leaving a remainder of 89.
Write down 7 as next digit of the result. 
Result so far: 57566.31548757
Deduct 3661 from 3750 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

The quotient of the division is 57566.31548757, and the remainder is 8.9e-08.
