Let's divide 74430123 by 900
The aim is to understand the frequency of 900 in 74430123.

Advancing to step 1:
900 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 900

Moving on to step 2:
The number 900 fits into 74 0 times, leaving a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Take the next digit (4) from the dividend and append it to 74, then repeat: 744 / 900

Let's proceed to step 3:
When dividing 744 by 900, we get 0 with a remainder of 744.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 744 leaves us with 744.
Grab the next digit (3) from the dividend, add it to 744, then carry on: 7443 / 900

Let's proceed to step 4:
900 can be fit into 7443 8 times, resulting in a remainder of 243.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 7200 from 7443 and we're left with 243.
Include the next digit (0) from the dividend after 243, then repeat: 2430 / 900

On to step 5:
2430 divided by 900 is 2 with a remainder of 630.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
Subtracting 1800 from 2430 leaves us with 630.
Fetch the next digit (1) from the dividend, attach it to 630 and continue: 6301 / 900

Step 6:
When dividing 6301 by 900, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 827.0
Deduct 6300 from 6301 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 900

On to step 7:
The number 900 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 8270.0
If we subtract 0 from 12, we get 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 900

Going ahead to step 8:
900 goes into 123 0 times with a remainder of 123.
Put 0 as the next digit of the answer. 
Result so far: 82700.0
If we take 0 away from 123, we end up 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.

Advancing to step 9:
900 goes into 1230 1 times with a remainder of 330.
The next digit of our result is 1. 
Result so far: 82700.1
If we take 900 away from 1230, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 10:
3300 divided by 900 is 3 with a remainder of 600.
Write down 3 as next digit of the result. 
Result so far: 82700.13
Deduct 2700 from 3300 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 11:
If we divide 6000 by 900, we get 6 and a remainder of 600.
The next digit of our result is 6. 
Result so far: 82700.136
If we subtract 5400 from 6000, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 12:
When dividing 6000 by 900, we get 6 with a remainder of 600.
The number 6 becomes the next digit in our result. 
Result so far: 82700.1366
The remainder is 600 after subtracting 5400 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The quotient of the division is 82700.1366, and the remainder is 0.006.
