51334690 ÷ 450 
The aim is to understand the frequency of 450 in 51334690.

Advancing to step 1:
If we divide 5 by 450, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 450

On to step 2:
When dividing 51 by 450, we get 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 450

Advancing to step 3:
If we divide 513 by 450, we get 1 and a remainder of 63.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 450 from 513 and we're left with 63.
Include the next digit (3) from the dividend after 63, then repeat: 633 / 450

Going ahead to step 4:
When dividing 633 by 450, we get 1 with a remainder of 183.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 183 after subtracting 450 from 633.
Fetch the next digit (4) from the dividend, attach it to 183 and continue: 1834 / 450

Let's proceed to step 5:
450 goes into 1834 4 times with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 114.0
The remainder is 34 after subtracting 1800 from 1834.
Fetch the next digit (6) from the dividend, attach it to 34 and continue: 346 / 450

Advancing to step 6:
450 can be fit into 346 0 times, resulting in a remainder of 346.
Record the quotient 0 as the next digit in the result. 
Result so far: 1140.0
Deduct 0 from 346 and we're left with 346.
Fetch the next digit (9) from the dividend, attach it to 346 and continue: 3469 / 450

On to step 7:
When dividing 3469 by 450, we get 7 with a remainder of 319.
Put 7 as the next digit of the answer. 
Result so far: 11407.0
Subtracting 3150 from 3469 leaves us with 319.
Bring next digit (0) of the dividend behind the 319 and repeat the process: 3190 / 450

Moving on to step 8:
When dividing 3190 by 450, we get 7 with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 114077.0
The remainder is 40 after subtracting 3150 from 3190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
400 divided by 450 is 0 with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 114077.0
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 10:
450 goes into 4000 8 times with a remainder of 400.
Record the quotient 8 as the next digit in the result. 
Result so far: 114077.08
If we take 3600 away from 4000, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 11:
450 goes into 4000 8 times with a remainder of 400.
Use 8 as the next digit of our solution. 
Result so far: 114077.088
Deduct 3600 from 4000 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 114077.088, with a leftover of 0.04.
