We look at the division of 91193349 by 900 
The aim is to understand the frequency of 900 in 91193349.

Going ahead to step 1:
9 divided by 900 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 900

Let's proceed to step 2:
91 divided by 900 is 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Take the next digit (1) from the dividend and append it to 91, then repeat: 911 / 900

Step 3:
900 goes into 911 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 900 away from 911, we end up with 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 900

Advancing to step 4:
When dividing 119 by 900, we get 0 with a remainder of 119.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 119 leaves us with 119.
Grab the next digit (3) from the dividend, add it to 119, then carry on: 1193 / 900

Going ahead to step 5:
1193 divided by 900 is 1 with a remainder of 293.
Put 1 as the next digit of the answer. 
Result so far: 101.0
The remainder is 293 after subtracting 900 from 1193.
Take the next digit (3) from the dividend and append it to 293, then repeat: 2933 / 900

Step 6:
When dividing 2933 by 900, we get 3 with a remainder of 233.
Put 3 as the next digit of the answer. 
Result so far: 1013.0
Subtract 2700 from 2933 to get 233.
Bring next digit (4) of the dividend behind the 233 and repeat the process: 2334 / 900

Going ahead to step 7:
900 goes into 2334 2 times with a remainder of 534.
The number 2 becomes the next digit in our result. 
Result so far: 10132.0
Subtracting 1800 from 2334 leaves us with 534.
Grab the next digit (9) from the dividend, add it to 534, then carry on: 5349 / 900

Moving on to step 8:
If we divide 5349 by 900, we get 5 and a remainder of 849.
The number 5 becomes the next digit in our result. 
Result so far: 101325.0
Subtract 4500 from 5349 to get 849.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8490, and continue the process.

Advancing to step 9:
When dividing 8490 by 900, we get 9 with a remainder of 390.
Record the quotient 9 as the next digit in the result. 
Result so far: 101325.9
If we take 8100 away from 8490, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 10:
If we divide 3900 by 900, we get 4 and a remainder of 300.
The number 4 becomes the next digit in our result. 
Result so far: 101325.94
If we subtract 3600 from 3900, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 11:
When dividing 3000 by 900, we get 3 with a remainder of 300.
The number 3 becomes the next digit in our result. 
Result so far: 101325.943
If we take 2700 away from 3000, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 12:
The number 900 fits into 3000 3 times, leaving a remainder of 300.
The number 3 becomes the next digit in our result. 
Result so far: 101325.9433
Deduct 2700 from 3000 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 101325.9433, with a leftover of 0.003.
