4356465 ÷ 990 
The aim is to understand the frequency of 990 in 4356465.

On to step 1:
If we divide 4 by 990, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 990

Step 2:
43 divided by 990 is 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Fetch the next digit (5) from the dividend, attach it to 43 and continue: 435 / 990

Going ahead to step 3:
990 goes into 435 0 times with a remainder of 435.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 435 and we're left with 435.
Grab the next digit (6) from the dividend, add it to 435, then carry on: 4356 / 990

Going ahead to step 4:
990 goes into 4356 4 times with a remainder of 396.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 3960 from 4356 leaves us with 396.
Take the next digit (4) from the dividend and append it to 396, then repeat: 3964 / 990

Let's proceed to step 5:
990 goes into 3964 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Subtract 3960 from 3964 to get 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 990

Going ahead to step 6:
If we divide 46 by 990, we get 0 and a remainder of 46.
Write down 0 as next digit of the result. 
Result so far: 440.0
The remainder is 46 after subtracting 0 from 46.
Grab the next digit (5) from the dividend, add it to 46, then carry on: 465 / 990

Moving on to step 7:
990 goes into 465 0 times with a remainder of 465.
Use 0 as the next digit of our solution. 
Result so far: 4400.0
Deduct 0 from 465 and we're left with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Step 8:
When dividing 4650 by 990, we get 4 with a remainder of 690.
The next digit of our result is 4. 
Result so far: 4400.4
The remainder is 690 after subtracting 3960 from 4650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Going ahead to step 9:
The number 990 fits into 6900 6 times, leaving a remainder of 960.
Write down 6 as next digit of the result. 
Result so far: 4400.46
If we take 5940 away from 6900, we end up with 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9600, and continue the process.

Advancing to step 10:
990 can be fit into 9600 9 times, resulting in a remainder of 690.
Record the quotient 9 as the next digit in the result. 
Result so far: 4400.469
Deduct 8910 from 9600 and we're left with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Step 11:
6900 divided by 990 is 6 with a remainder of 960.
Use 6 as the next digit of our solution. 
Result so far: 4400.4696
Subtract 5940 from 6900 to get 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9600, and continue the process.

On to step 12:
The number 990 fits into 9600 9 times, leaving a remainder of 690.
Record the quotient 9 as the next digit in the result. 
Result so far: 4400.46969
If we subtract 8910 from 9600, we get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

On to step 13:
6900 divided by 990 is 6 with a remainder of 960.
The next digit of our result is 6. 
Result so far: 4400.469696
The remainder is 960 after subtracting 5940 from 6900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9600, and continue the process.

Let's proceed to step 14:
990 goes into 9600 9 times with a remainder of 690.
Put 9 as the next digit of the answer. 
Result so far: 4400.4696969
Subtract 8910 from 9600 to get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Advancing to step 15:
The number 990 fits into 6900 6 times, leaving a remainder of 960.
Record the quotient 6 as the next digit in the result. 
Result so far: 4400.46969696
Subtract 5940 from 6900 to get 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9600, and continue the process.

Our division results in 4400.46969696 with a remaining 9.6e-07.
