We look at the division of 80469484 by 398 
We want to figure out the number of times 80469484 can be divided by 398.

On to step 1:
If we divide 8 by 398, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 398

Advancing to step 2:
398 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Bring next digit (4) of the dividend behind the 80 and repeat the process: 804 / 398

Moving on to step 3:
When dividing 804 by 398, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 796 from 804 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 398

Advancing to step 4:
398 can be fit into 86 0 times, resulting in a remainder of 86.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 86 to get 86.
Append the next digit (9) from the dividend to 86 and continue with: 869 / 398

On to step 5:
The number 398 fits into 869 2 times, leaving a remainder of 73.
Write down 2 as next digit of the result. 
Result so far: 202.0
If we subtract 796 from 869, we get 73.
Include the next digit (4) from the dividend after 73, then repeat: 734 / 398

Moving on to step 6:
When dividing 734 by 398, we get 1 with a remainder of 336.
Put 1 as the next digit of the answer. 
Result so far: 2021.0
If we take 398 away from 734, we end up with 336.
Append the next digit (8) from the dividend to 336 and continue with: 3368 / 398

Let's proceed to step 7:
When dividing 3368 by 398, we get 8 with a remainder of 184.
The next digit of our result is 8. 
Result so far: 20218.0
Deduct 3184 from 3368 and we're left with 184.
Bring next digit (4) of the dividend behind the 184 and repeat the process: 1844 / 398

Moving on to step 8:
398 goes into 1844 4 times with a remainder of 252.
The number 4 becomes the next digit in our result. 
Result so far: 202184.0
If we take 1592 away from 1844, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 9:
398 goes into 2520 6 times with a remainder of 132.
Write down 6 as next digit of the result. 
Result so far: 202184.6
If we subtract 2388 from 2520, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 10:
If we divide 1320 by 398, we get 3 and a remainder of 126.
The next digit of our result is 3. 
Result so far: 202184.63
If we take 1194 away from 1320, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 11:
398 goes into 1260 3 times with a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 202184.633
Deduct 1194 from 1260 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

After the division, we end up with 202184.633 and a remainder of 0.0066.
