Let's divide 51476521 by 823
The aim is to understand the frequency of 823 in 51476521.

On to step 1:
When dividing 5 by 823, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 823

Going ahead to step 2:
51 divided by 823 is 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Take the next digit (4) from the dividend and append it to 51, then repeat: 514 / 823

Let's proceed to step 3:
When dividing 514 by 823, we get 0 with a remainder of 514.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 514, we end up with 514.
Grab the next digit (7) from the dividend, add it to 514, then carry on: 5147 / 823

Step 4:
If we divide 5147 by 823, we get 6 and a remainder of 209.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 4938 from 5147, we get 209.
Fetch the next digit (6) from the dividend, attach it to 209 and continue: 2096 / 823

On to step 5:
2096 divided by 823 is 2 with a remainder of 450.
Put 2 as the next digit of the answer. 
Result so far: 62.0
If we take 1646 away from 2096, we end up with 450.
Include the next digit (5) from the dividend after 450, then repeat: 4505 / 823

Step 6:
If we divide 4505 by 823, we get 5 and a remainder of 390.
Use 5 as the next digit of our solution. 
Result so far: 625.0
Subtracting 4115 from 4505 leaves us with 390.
Bring next digit (2) of the dividend behind the 390 and repeat the process: 3902 / 823

Advancing to step 7:
If we divide 3902 by 823, we get 4 and a remainder of 610.
Record the quotient 4 as the next digit in the result. 
Result so far: 6254.0
If we subtract 3292 from 3902, we get 610.
Fetch the next digit (1) from the dividend, attach it to 610 and continue: 6101 / 823

Going ahead to step 8:
The number 823 fits into 6101 7 times, leaving a remainder of 340.
The next digit of our result is 7. 
Result so far: 62547.0
If we subtract 5761 from 6101, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 9:
If we divide 3400 by 823, we get 4 and a remainder of 108.
The next digit of our result is 4. 
Result so far: 62547.4
Deduct 3292 from 3400 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 10:
823 can be fit into 1080 1 times, resulting in a remainder of 257.
The number 1 becomes the next digit in our result. 
Result so far: 62547.41
Subtracting 823 from 1080 leaves us with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

On to step 11:
If we divide 2570 by 823, we get 3 and a remainder of 101.
Record the quotient 3 as the next digit in the result. 
Result so far: 62547.413
Subtracting 2469 from 2570 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Step 12:
The number 823 fits into 1010 1 times, leaving a remainder of 187.
Use 1 as the next digit of our solution. 
Result so far: 62547.4131
Subtract 823 from 1010 to get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Let's proceed to step 13:
When dividing 1870 by 823, we get 2 with a remainder of 224.
Put 2 as the next digit of the answer. 
Result so far: 62547.41312
Deduct 1646 from 1870 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 14:
823 goes into 2240 2 times with a remainder of 594.
Put 2 as the next digit of the answer. 
Result so far: 62547.413122
If we subtract 1646 from 2240, we get 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Our division results in 62547.413122 with a remaining 5.94e-05.
