74815312 ÷ 799 
The aim is to understand the frequency of 799 in 74815312.

On to step 1:
If we divide 7 by 799, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 799

Advancing to step 2:
799 goes into 74 0 times with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Fetch the next digit (8) from the dividend, attach it to 74 and continue: 748 / 799

On to step 3:
799 goes into 748 0 times with a remainder of 748.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 748, we end up with 748.
Include the next digit (1) from the dividend after 748, then repeat: 7481 / 799

Let's proceed to step 4:
The number 799 fits into 7481 9 times, leaving a remainder of 290.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 7191 from 7481 to get 290.
Append the next digit (5) from the dividend to 290 and continue with: 2905 / 799

Step 5:
If we divide 2905 by 799, we get 3 and a remainder of 508.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
The remainder is 508 after subtracting 2397 from 2905.
Fetch the next digit (3) from the dividend, attach it to 508 and continue: 5083 / 799

Moving on to step 6:
If we divide 5083 by 799, we get 6 and a remainder of 289.
Use 6 as the next digit of our solution. 
Result so far: 936.0
Subtracting 4794 from 5083 leaves us with 289.
Bring next digit (1) of the dividend behind the 289 and repeat the process: 2891 / 799

Let's proceed to step 7:
2891 divided by 799 is 3 with a remainder of 494.
Put 3 as the next digit of the answer. 
Result so far: 9363.0
Subtracting 2397 from 2891 leaves us with 494.
Bring next digit (2) of the dividend behind the 494 and repeat the process: 4942 / 799

Advancing to step 8:
799 goes into 4942 6 times with a remainder of 148.
The next digit of our result is 6. 
Result so far: 93636.0
If we take 4794 away from 4942, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 9:
799 goes into 1480 1 times with a remainder of 681.
The number 1 becomes the next digit in our result. 
Result so far: 93636.1
The remainder is 681 after subtracting 799 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

On to step 10:
799 can be fit into 6810 8 times, resulting in a remainder of 418.
Put 8 as the next digit of the answer. 
Result so far: 93636.18
Subtract 6392 from 6810 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

On to step 11:
4180 divided by 799 is 5 with a remainder of 185.
The next digit of our result is 5. 
Result so far: 93636.185
Subtracting 3995 from 4180 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 12:
799 goes into 1850 2 times with a remainder of 252.
Use 2 as the next digit of our solution. 
Result so far: 93636.1852
If we take 1598 away from 1850, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 13:
2520 divided by 799 is 3 with a remainder of 123.
Write down 3 as next digit of the result. 
Result so far: 93636.18523
Subtracting 2397 from 2520 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Moving on to step 14:
If we divide 1230 by 799, we get 1 and a remainder of 431.
Put 1 as the next digit of the answer. 
Result so far: 93636.185231
Deduct 799 from 1230 and we're left with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Step 15:
799 goes into 4310 5 times with a remainder of 315.
The next digit of our result is 5. 
Result so far: 93636.1852315
If we subtract 3995 from 4310, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Step 16:
When dividing 3150 by 799, we get 3 with a remainder of 753.
Put 3 as the next digit of the answer. 
Result so far: 93636.18523153
If we take 2397 away from 3150, we end up with 753.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7530, and continue the process.

The quotient of the division is 93636.18523153, and the remainder is 7.53e-07.
