8474857 divided by 450 
The aim is to understand the frequency of 450 in 8474857.

Advancing to step 1:
450 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 450

On to step 2:
The number 450 fits into 84 0 times, leaving a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Append the next digit (7) from the dividend to 84 and continue with: 847 / 450

Going ahead to step 3:
When dividing 847 by 450, we get 1 with a remainder of 397.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 450 from 847 leaves us with 397.
Fetch the next digit (4) from the dividend, attach it to 397 and continue: 3974 / 450

Going ahead to step 4:
450 can be fit into 3974 8 times, resulting in a remainder of 374.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtracting 3600 from 3974 leaves us with 374.
Grab the next digit (8) from the dividend, add it to 374, then carry on: 3748 / 450

Step 5:
If we divide 3748 by 450, we get 8 and a remainder of 148.
Put 8 as the next digit of the answer. 
Result so far: 188.0
Subtracting 3600 from 3748 leaves us with 148.
Take the next digit (5) from the dividend and append it to 148, then repeat: 1485 / 450

Going ahead to step 6:
450 can be fit into 1485 3 times, resulting in a remainder of 135.
Write down 3 as next digit of the result. 
Result so far: 1883.0
The remainder is 135 after subtracting 1350 from 1485.
Grab the next digit (7) from the dividend, add it to 135, then carry on: 1357 / 450

Let's proceed to step 7:
1357 divided by 450 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 18833.0
The remainder is 7 after subtracting 1350 from 1357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
The number 450 fits into 70 0 times, leaving a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 18833.0
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
If we divide 700 by 450, we get 1 and a remainder of 250.
The number 1 becomes the next digit in our result. 
Result so far: 18833.01
If we subtract 450 from 700, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 10:
450 goes into 2500 5 times with a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 18833.015
If we take 2250 away from 2500, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 11:
450 can be fit into 2500 5 times, resulting in a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 18833.0155
The remainder is 250 after subtracting 2250 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The quotient of the division is 18833.0155, and the remainder is 0.0025.
