We're dividing 55458098 by 454 
We want to figure out the number of times 55458098 can be divided by 454.

Step 1:
The number 454 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 454

Step 2:
55 divided by 454 is 0 with a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Include the next digit (4) from the dividend after 55, then repeat: 554 / 454

Advancing to step 3:
454 can be fit into 554 1 times, resulting in a remainder of 100.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 454 from 554 to get 100.
Take the next digit (5) from the dividend and append it to 100, then repeat: 1005 / 454

Moving on to step 4:
The number 454 fits into 1005 2 times, leaving a remainder of 97.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 908 from 1005 leaves us with 97.
Append the next digit (8) from the dividend to 97 and continue with: 978 / 454

On to step 5:
454 goes into 978 2 times with a remainder of 70.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
If we subtract 908 from 978, we get 70.
Include the next digit (0) from the dividend after 70, then repeat: 700 / 454

Moving on to step 6:
If we divide 700 by 454, we get 1 and a remainder of 246.
The next digit of our result is 1. 
Result so far: 1221.0
If we subtract 454 from 700, we get 246.
Bring next digit (9) of the dividend behind the 246 and repeat the process: 2469 / 454

Step 7:
When dividing 2469 by 454, we get 5 with a remainder of 199.
Put 5 as the next digit of the answer. 
Result so far: 12215.0
If we take 2270 away from 2469, we end up with 199.
Grab the next digit (8) from the dividend, add it to 199, then carry on: 1998 / 454

Step 8:
When dividing 1998 by 454, we get 4 with a remainder of 182.
Record the quotient 4 as the next digit in the result. 
Result so far: 122154.0
The remainder is 182 after subtracting 1816 from 1998.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 9:
If we divide 1820 by 454, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 122154.4
If we take 1816 away from 1820, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
If we divide 40 by 454, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 122154.4
If we take 0 away from 40, we end up with 40.
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 11:
When dividing 400 by 454, we get 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 122154.4
If we subtract 0 from 400, we get 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 result is 122154.4 with a remainder of 0.04.
