Let's divide 69958328 by 900
The aim is to understand the frequency of 900 in 69958328.

On to step 1:
900 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 900

Moving on to step 2:
When dividing 69 by 900, we get 0 with a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Fetch the next digit (9) from the dividend, attach it to 69 and continue: 699 / 900

Step 3:
If we divide 699 by 900, we get 0 and a remainder of 699.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 699 after subtracting 0 from 699.
Include the next digit (5) from the dividend after 699, then repeat: 6995 / 900

On to step 4:
If we divide 6995 by 900, we get 7 and a remainder of 695.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 6300 from 6995, we get 695.
Include the next digit (8) from the dividend after 695, then repeat: 6958 / 900

Step 5:
900 goes into 6958 7 times with a remainder of 658.
Write down 7 as next digit of the result. 
Result so far: 77.0
Deduct 6300 from 6958 and we're left with 658.
Include the next digit (3) from the dividend after 658, then repeat: 6583 / 900

Advancing to step 6:
The number 900 fits into 6583 7 times, leaving a remainder of 283.
The number 7 becomes the next digit in our result. 
Result so far: 777.0
Deduct 6300 from 6583 and we're left with 283.
Grab the next digit (2) from the dividend, add it to 283, then carry on: 2832 / 900

Advancing to step 7:
900 can be fit into 2832 3 times, resulting in a remainder of 132.
The next digit of our result is 3. 
Result so far: 7773.0
The remainder is 132 after subtracting 2700 from 2832.
Take the next digit (8) from the dividend and append it to 132, then repeat: 1328 / 900

Advancing to step 8:
1328 divided by 900 is 1 with a remainder of 428.
The next digit of our result is 1. 
Result so far: 77731.0
Deduct 900 from 1328 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Moving on to step 9:
If we divide 4280 by 900, we get 4 and a remainder of 680.
Write down 4 as next digit of the result. 
Result so far: 77731.4
Deduct 3600 from 4280 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Moving on to step 10:
900 can be fit into 6800 7 times, resulting in a remainder of 500.
Use 7 as the next digit of our solution. 
Result so far: 77731.47
If we take 6300 away from 6800, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 11:
900 can be fit into 5000 5 times, resulting in a remainder of 500.
Use 5 as the next digit of our solution. 
Result so far: 77731.475
If we subtract 4500 from 5000, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 12:
900 goes into 5000 5 times with a remainder of 500.
Put 5 as the next digit of the answer. 
Result so far: 77731.4755
If we subtract 4500 from 5000, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Our division results in 77731.4755 with a remaining 0.005.
