76904528 ÷ 823 
The aim is to understand the frequency of 823 in 76904528.

On to step 1:
823 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 823

Going ahead to step 2:
If we divide 76 by 823, we get 0 and a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Grab the next digit (9) from the dividend, add it to 76, then carry on: 769 / 823

Step 3:
The number 823 fits into 769 0 times, leaving a remainder of 769.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 769, we get 769.
Bring next digit (0) of the dividend behind the 769 and repeat the process: 7690 / 823

Advancing to step 4:
823 goes into 7690 9 times with a remainder of 283.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 7407 away from 7690, we end up with 283.
Include the next digit (4) from the dividend after 283, then repeat: 2834 / 823

Advancing to step 5:
If we divide 2834 by 823, we get 3 and a remainder of 365.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
If we take 2469 away from 2834, we end up with 365.
Grab the next digit (5) from the dividend, add it to 365, then carry on: 3655 / 823

Moving on to step 6:
3655 divided by 823 is 4 with a remainder of 363.
Record the quotient 4 as the next digit in the result. 
Result so far: 934.0
The remainder is 363 after subtracting 3292 from 3655.
Take the next digit (2) from the dividend and append it to 363, then repeat: 3632 / 823

Let's proceed to step 7:
823 goes into 3632 4 times with a remainder of 340.
The next digit of our result is 4. 
Result so far: 9344.0
The remainder is 340 after subtracting 3292 from 3632.
Append the next digit (8) from the dividend to 340 and continue with: 3408 / 823

Going ahead to step 8:
If we divide 3408 by 823, we get 4 and a remainder of 116.
Put 4 as the next digit of the answer. 
Result so far: 93444.0
Subtract 3292 from 3408 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 9:
823 can be fit into 1160 1 times, resulting in a remainder of 337.
The next digit of our result is 1. 
Result so far: 93444.1
Subtracting 823 from 1160 leaves us with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Advancing to step 10:
3370 divided by 823 is 4 with a remainder of 78.
Use 4 as the next digit of our solution. 
Result so far: 93444.14
The remainder is 78 after subtracting 3292 from 3370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 11:
823 can be fit into 780 0 times, resulting in a remainder of 780.
Use 0 as the next digit of our solution. 
Result so far: 93444.14
Subtracting 0 from 780 leaves us with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Moving on to step 12:
When dividing 7800 by 823, we get 9 with a remainder of 393.
Use 9 as the next digit of our solution. 
Result so far: 93444.1409
If we subtract 7407 from 7800, we get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

On to step 13:
When dividing 3930 by 823, we get 4 with a remainder of 638.
Record the quotient 4 as the next digit in the result. 
Result so far: 93444.14094
If we subtract 3292 from 3930, we get 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Going ahead to step 14:
823 can be fit into 6380 7 times, resulting in a remainder of 619.
Use 7 as the next digit of our solution. 
Result so far: 93444.140947
Subtracting 5761 from 6380 leaves us with 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Advancing to step 15:
The number 823 fits into 6190 7 times, leaving a remainder of 429.
Put 7 as the next digit of the answer. 
Result so far: 93444.1409477
Subtracting 5761 from 6190 leaves us with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

After the division, we end up with 93444.1409477 and a remainder of 4.29e-06.
