45677818 ÷ 900 
The aim is to understand the frequency of 900 in 45677818.

Advancing to step 1:
When dividing 4 by 900, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 900

On to step 2:
45 divided by 900 is 0 with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Take the next digit (6) from the dividend and append it to 45, then repeat: 456 / 900

Let's proceed to step 3:
900 can be fit into 456 0 times, resulting in a remainder of 456.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 456 to get 456.
Grab the next digit (7) from the dividend, add it to 456, then carry on: 4567 / 900

On to step 4:
4567 divided by 900 is 5 with a remainder of 67.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 4500 from 4567, we get 67.
Grab the next digit (7) from the dividend, add it to 67, then carry on: 677 / 900

On to step 5:
677 divided by 900 is 0 with a remainder of 677.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
The remainder is 677 after subtracting 0 from 677.
Grab the next digit (8) from the dividend, add it to 677, then carry on: 6778 / 900

Advancing to step 6:
If we divide 6778 by 900, we get 7 and a remainder of 478.
Put 7 as the next digit of the answer. 
Result so far: 507.0
If we subtract 6300 from 6778, we get 478.
Bring next digit (1) of the dividend behind the 478 and repeat the process: 4781 / 900

Advancing to step 7:
When dividing 4781 by 900, we get 5 with a remainder of 281.
Put 5 as the next digit of the answer. 
Result so far: 5075.0
If we take 4500 away from 4781, we end up with 281.
Bring next digit (8) of the dividend behind the 281 and repeat the process: 2818 / 900

Let's proceed to step 8:
2818 divided by 900 is 3 with a remainder of 118.
Use 3 as the next digit of our solution. 
Result so far: 50753.0
Subtracting 2700 from 2818 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 9:
1180 divided by 900 is 1 with a remainder of 280.
Put 1 as the next digit of the answer. 
Result so far: 50753.1
Subtracting 900 from 1180 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 10:
If we divide 2800 by 900, we get 3 and a remainder of 100.
Use 3 as the next digit of our solution. 
Result so far: 50753.13
Deduct 2700 from 2800 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
1000 divided by 900 is 1 with a remainder of 100.
Write down 1 as next digit of the result. 
Result so far: 50753.131
If we subtract 900 from 1000, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 12:
900 can be fit into 1000 1 times, resulting in a remainder of 100.
The next digit of our result is 1. 
Result so far: 50753.1311
Subtract 900 from 1000 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 50753.1311 and a remainder of 0.001.
