79049536 ÷ 990 
The aim is to understand the frequency of 990 in 79049536.

Let's proceed to step 1:
990 goes into 7 0 times with 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.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 990

Going ahead to step 2:
If we divide 79 by 990, we get 0 and a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Include the next digit (0) from the dividend after 79, then repeat: 790 / 990

Moving on to step 3:
790 divided by 990 is 0 with a remainder of 790.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 790 leaves us with 790.
Grab the next digit (4) from the dividend, add it to 790, then carry on: 7904 / 990

Let's proceed to step 4:
The number 990 fits into 7904 7 times, leaving a remainder of 974.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 974 after subtracting 6930 from 7904.
Take the next digit (9) from the dividend and append it to 974, then repeat: 9749 / 990

Let's proceed to step 5:
990 goes into 9749 9 times with a remainder of 839.
Put 9 as the next digit of the answer. 
Result so far: 79.0
If we take 8910 away from 9749, we end up with 839.
Append the next digit (5) from the dividend to 839 and continue with: 8395 / 990

Let's proceed to step 6:
990 goes into 8395 8 times with a remainder of 475.
Put 8 as the next digit of the answer. 
Result so far: 798.0
If we take 7920 away from 8395, we end up with 475.
Grab the next digit (3) from the dividend, add it to 475, then carry on: 4753 / 990

Step 7:
990 goes into 4753 4 times with a remainder of 793.
Write down 4 as next digit of the result. 
Result so far: 7984.0
Subtract 3960 from 4753 to get 793.
Take the next digit (6) from the dividend and append it to 793, then repeat: 7936 / 990

On to step 8:
990 goes into 7936 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 79848.0
Deduct 7920 from 7936 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
990 goes into 160 0 times with a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 79848.0
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 10:
The number 990 fits into 1600 1 times, leaving a remainder of 610.
Write down 1 as next digit of the result. 
Result so far: 79848.01
If we subtract 990 from 1600, we get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Moving on to step 11:
If we divide 6100 by 990, we get 6 and a remainder of 160.
Put 6 as the next digit of the answer. 
Result so far: 79848.016
If we take 5940 away from 6100, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 12:
1600 divided by 990 is 1 with a remainder of 610.
The number 1 becomes the next digit in our result. 
Result so far: 79848.0161
If we take 990 away from 1600, we end up with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Advancing to step 13:
990 can be fit into 6100 6 times, resulting in a remainder of 160.
Record the quotient 6 as the next digit in the result. 
Result so far: 79848.01616
If we take 5940 away from 6100, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 14:
990 can be fit into 1600 1 times, resulting in a remainder of 610.
Record the quotient 1 as the next digit in the result. 
Result so far: 79848.016161
The remainder is 610 after subtracting 990 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Going ahead to step 15:
When dividing 6100 by 990, we get 6 with a remainder of 160.
Put 6 as the next digit of the answer. 
Result so far: 79848.0161616
If we take 5940 away from 6100, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 16:
The number 990 fits into 1600 1 times, leaving a remainder of 610.
Record the quotient 1 as the next digit in the result. 
Result so far: 79848.01616161
The remainder is 610 after subtracting 990 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

The quotient of the division is 79848.01616161, and the remainder is 6.1e-07.
