We look at the division of 84419885 by 454 
We want to figure out the number of times 84419885 can be divided by 454.

Step 1:
If we divide 8 by 454, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 454

Moving on to step 2:
454 can be fit into 84 0 times, resulting in a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Include the next digit (4) from the dividend after 84, then repeat: 844 / 454

Step 3:
When dividing 844 by 454, we get 1 with a remainder of 390.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 454 from 844 to get 390.
Grab the next digit (1) from the dividend, add it to 390, then carry on: 3901 / 454

Moving on to step 4:
The number 454 fits into 3901 8 times, leaving a remainder of 269.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 3632 from 3901 leaves us with 269.
Fetch the next digit (9) from the dividend, attach it to 269 and continue: 2699 / 454

Step 5:
2699 divided by 454 is 5 with a remainder of 429.
The next digit of our result is 5. 
Result so far: 185.0
The remainder is 429 after subtracting 2270 from 2699.
Grab the next digit (8) from the dividend, add it to 429, then carry on: 4298 / 454

Going ahead to step 6:
454 can be fit into 4298 9 times, resulting in a remainder of 212.
Write down 9 as next digit of the result. 
Result so far: 1859.0
Subtract 4086 from 4298 to get 212.
Include the next digit (8) from the dividend after 212, then repeat: 2128 / 454

Step 7:
454 can be fit into 2128 4 times, resulting in a remainder of 312.
The next digit of our result is 4. 
Result so far: 18594.0
If we subtract 1816 from 2128, we get 312.
Bring next digit (5) of the dividend behind the 312 and repeat the process: 3125 / 454

Moving on to step 8:
454 goes into 3125 6 times with a remainder of 401.
Use 6 as the next digit of our solution. 
Result so far: 185946.0
Subtracting 2724 from 3125 leaves us with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Moving on to step 9:
454 can be fit into 4010 8 times, resulting in a remainder of 378.
Put 8 as the next digit of the answer. 
Result so far: 185946.8
If we subtract 3632 from 4010, we get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Advancing to step 10:
3780 divided by 454 is 8 with a remainder of 148.
Write down 8 as next digit of the result. 
Result so far: 185946.88
The remainder is 148 after subtracting 3632 from 3780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

The final result is 185946.88 with a remainder of 0.148.
