82784233 ÷ 990 
The aim is to understand the frequency of 990 in 82784233.

Advancing to step 1:
If we divide 8 by 990, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 990

Advancing to step 2:
990 goes into 82 0 times with a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 82 to get 82.
Grab the next digit (7) from the dividend, add it to 82, then carry on: 827 / 990

Going ahead to step 3:
827 divided by 990 is 0 with a remainder of 827.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 827 after subtracting 0 from 827.
Fetch the next digit (8) from the dividend, attach it to 827 and continue: 8278 / 990

Going ahead to step 4:
If we divide 8278 by 990, we get 8 and a remainder of 358.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 7920 away from 8278, we end up with 358.
Grab the next digit (4) from the dividend, add it to 358, then carry on: 3584 / 990

Advancing to step 5:
When dividing 3584 by 990, we get 3 with a remainder of 614.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Subtract 2970 from 3584 to get 614.
Include the next digit (2) from the dividend after 614, then repeat: 6142 / 990

Moving on to step 6:
When dividing 6142 by 990, we get 6 with a remainder of 202.
Use 6 as the next digit of our solution. 
Result so far: 836.0
Deduct 5940 from 6142 and we're left with 202.
Bring next digit (3) of the dividend behind the 202 and repeat the process: 2023 / 990

Going ahead to step 7:
990 goes into 2023 2 times with a remainder of 43.
Write down 2 as next digit of the result. 
Result so far: 8362.0
Subtract 1980 from 2023 to get 43.
Take the next digit (3) from the dividend and append it to 43, then repeat: 433 / 990

Advancing to step 8:
The number 990 fits into 433 0 times, leaving a remainder of 433.
Record the quotient 0 as the next digit in the result. 
Result so far: 83620.0
If we subtract 0 from 433, we get 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

On to step 9:
4330 divided by 990 is 4 with a remainder of 370.
Use 4 as the next digit of our solution. 
Result so far: 83620.4
Deduct 3960 from 4330 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 10:
3700 divided by 990 is 3 with a remainder of 730.
Use 3 as the next digit of our solution. 
Result so far: 83620.43
If we take 2970 away from 3700, we end up with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Moving on to step 11:
990 goes into 7300 7 times with a remainder of 370.
Put 7 as the next digit of the answer. 
Result so far: 83620.437
Subtract 6930 from 7300 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 12:
990 goes into 3700 3 times with a remainder of 730.
The number 3 becomes the next digit in our result. 
Result so far: 83620.4373
Subtract 2970 from 3700 to get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

On to step 13:
When dividing 7300 by 990, we get 7 with a remainder of 370.
The next digit of our result is 7. 
Result so far: 83620.43737
If we take 6930 away from 7300, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 14:
If we divide 3700 by 990, we get 3 and a remainder of 730.
Write down 3 as next digit of the result. 
Result so far: 83620.437373
Deduct 2970 from 3700 and we're left with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Let's proceed to step 15:
990 can be fit into 7300 7 times, resulting in a remainder of 370.
The next digit of our result is 7. 
Result so far: 83620.4373737
If we take 6930 away from 7300, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 16:
990 can be fit into 3700 3 times, resulting in a remainder of 730.
The number 3 becomes the next digit in our result. 
Result so far: 83620.43737373
If we subtract 2970 from 3700, we get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

The final outcome is 83620.43737373, with a leftover of 7.3e-07.
