We're dividing 56388169 by 990 
The aim is to understand the frequency of 990 in 56388169.

Step 1:
990 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 990

Step 2:
When dividing 56 by 990, we get 0 with a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 56, we end up with 56.
Fetch the next digit (3) from the dividend, attach it to 56 and continue: 563 / 990

Step 3:
When dividing 563 by 990, we get 0 with a remainder of 563.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 563 to get 563.
Bring next digit (8) of the dividend behind the 563 and repeat the process: 5638 / 990

Going ahead to step 4:
990 can be fit into 5638 5 times, resulting in a remainder of 688.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 4950 from 5638 to get 688.
Bring next digit (8) of the dividend behind the 688 and repeat the process: 6888 / 990

On to step 5:
6888 divided by 990 is 6 with a remainder of 948.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
If we subtract 5940 from 6888, we get 948.
Include the next digit (1) from the dividend after 948, then repeat: 9481 / 990

Let's proceed to step 6:
If we divide 9481 by 990, we get 9 and a remainder of 571.
The number 9 becomes the next digit in our result. 
Result so far: 569.0
Subtract 8910 from 9481 to get 571.
Take the next digit (6) from the dividend and append it to 571, then repeat: 5716 / 990

Going ahead to step 7:
990 can be fit into 5716 5 times, resulting in a remainder of 766.
Use 5 as the next digit of our solution. 
Result so far: 5695.0
The remainder is 766 after subtracting 4950 from 5716.
Bring next digit (9) of the dividend behind the 766 and repeat the process: 7669 / 990

On to step 8:
The number 990 fits into 7669 7 times, leaving a remainder of 739.
Record the quotient 7 as the next digit in the result. 
Result so far: 56957.0
If we take 6930 away from 7669, we end up with 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

Advancing to step 9:
990 can be fit into 7390 7 times, resulting in a remainder of 460.
The number 7 becomes the next digit in our result. 
Result so far: 56957.7
Subtract 6930 from 7390 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 10:
4600 divided by 990 is 4 with a remainder of 640.
The next digit of our result is 4. 
Result so far: 56957.74
Deduct 3960 from 4600 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 11:
6400 divided by 990 is 6 with a remainder of 460.
Record the quotient 6 as the next digit in the result. 
Result so far: 56957.746
Deduct 5940 from 6400 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 12:
990 goes into 4600 4 times with a remainder of 640.
Record the quotient 4 as the next digit in the result. 
Result so far: 56957.7464
Deduct 3960 from 4600 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 13:
990 goes into 6400 6 times with a remainder of 460.
Put 6 as the next digit of the answer. 
Result so far: 56957.74646
Deduct 5940 from 6400 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 14:
990 goes into 4600 4 times with a remainder of 640.
Put 4 as the next digit of the answer. 
Result so far: 56957.746464
Subtracting 3960 from 4600 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 15:
When dividing 6400 by 990, we get 6 with a remainder of 460.
Write down 6 as next digit of the result. 
Result so far: 56957.7464646
Deduct 5940 from 6400 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 16:
If we divide 4600 by 990, we get 4 and a remainder of 640.
Use 4 as the next digit of our solution. 
Result so far: 56957.74646464
Subtracting 3960 from 4600 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

After the division, we end up with 56957.74646464 and a remainder of 6.4e-07.
